Krikzz is that your own NES core running on the FPGA?

So far it seems that it will have all the features of the X7, that's good news! I've also been holding out for this! :D

The FPGA NES is a nice little bonus and better than an emulator. In the video with SMB it sounds like Krikzz reversed the NES APU square channels' 25% and 50% duty cycles, like on some clones. Krikzz probably grew up with Famiclones, so it's not that strange if that's what he did.

I'm still not clear whether save states will be available for Sega CD and/or NES games.  Can anyone confirm?
Title: Re: Mega ED Pro
Post by: nuu on June 11, 2020, 10:46 PM
I don't know about the Mega CD, but since the entire NES is in the FPGA Krikzz should be able to do anything he wants with it. It will surly have save states.

Not sure I'd go that far - FPGAs are only as good as the coder, so they can be less accurate than some of the better NES emulators out there like Mesen. I would imagine it will take time for KRIKzz to get right, especially since he has a lot of projects on his plate.

Sure but an emulator is only as good as the coder as well. FPGA might be harder to code though, Krikzz has some good experience in this area.
For me this is not much more than a little bonus toy though, since I have a real Famicom and Everdrive N8. Being FPGA it's a more interesting toy than just another emulator would be. Besides I don't think the Mega Drive is powerful enough to run a NES emulator.

I’m really excited about this flashcart. Just hoping the input lag wont be to anoying on the NES fpga.

Post by: pharaohyami5000 on June 12, 2020, 11:19 PM
So just to clarify, would this Mega Everdrive Pro play all Sega games? Outside of Dreamcast, and... maybe Game Gear, SG-1000, and Master System (would it be able to play those)?

Oh, I don't disagree. I'm just saying we probably shouldn't expect Nestopia/Mesen levels of accuracy right off the bat, both of which are nearly as good as an actual system.

Yeah, and we might also have to expect Famiclone behaviour by default.

So just to clarify, would this Mega Everdrive Pro play all Sega games? Outside of Dreamcast, and... maybe Game Gear, SG-1000, and Master System (would it be able to play those)?
A fair guess is that it will probably be able to do everything the X7 can do (it's more expensive). In that case it should be able to play Mega Drive and Master System games. SG-1000, SC-3000 and Game Gear are all impossible because the Mega Drive is missing the required hardware. Some SMS games that uses some of the SG-1000 hardware features also won't work on a Mega Drive.

I don't know the compatibility of the X7, but since there are few mappers and it supports EEPROM saving, I wildly guess that 95+% of MD cartridge games and 90+% of SMS games works. Since SVP is now also supported that's another game added to the list (Virtua Racing).
No one knows how many Mega CD games are supported.


FPGA-based clones generally doesn't have any real input lag.
Title: Re: Mega ED Pro
Post by: phoenixdownita on June 13, 2020, 05:54 AM
Even if the NES only runs 50% of the games it is a tremendous gift.

AND the fact that Krikzz ported it to the Mega ED Pro opens up the possibilities for other cores.
He can write/port one for SG-1000/SC-3000 and potentially an approximate one (if it fits) for Game Gear (Sega MageDrive = 512 color palette, Sage Game Gear = 4096). If the GG fits for sure the SMS one can too (just to get that 3 games that use the legacy mode .... just kidding here, and GG too).
ColecoVision and MSX are in the same ballpark as SG1000 to be fair.

Note that controllers and video are still on the Genny, so there are limits but I can see a few other 8bits systems potentially be portable, even better if Krikzz releases an SDK for other people to write/port new cores

It's quite a unique capability in a way ... well done.
Title: Re: Mega ED Pro
Post by: Jiro on June 13, 2020, 07:24 AM
Technically 35 Master System games (https://www.smspower.org/Tags/LegacyVideo) use SG-1000 legacy mode, although only one of them is not a Korean port from MSX.  I don't know if he'd have to write an entire Master System core or if it would be possible to somehow override the display processor from the cartridge slot and add the mode.

Edit: Fixed link
Title: Re: Mega ED Pro
Post by: nuu on June 13, 2020, 01:39 PM
Oh it's that many? I think it could still be more than that, since it's enough for a game to use a hybrid of Mark III mode (VDP mode 4) and legacy settings, like the TMS9918 VDP's sprite zoom setting, for an SMS game to break on MD. If a game only uses pure SG-1000 legacy features, it can't really be called an SMS game though, it's an SG-1000/SC-3000 game.

I guess it could be possible to intercept any access to SG-1000 legacy hardware and reroute them to an FPGA clone in the Everdrive, and let it use the Mega Drive hardware for everything that is supported (like the PSG, RAM and controller ports). SC-3000 would probably require an FPGA clone of the keyboard hardware as well, and some way to hook up a keyboard.

I'm mainly interested in using the MD hardware (i.e. MD and SMS games), but I wouldn't mind if these flashcarts could be used as an alternative to a MiSTer in some cases.

If you want some unbiased conclusion then wait for reviews, if you interesting in my own point then next features at least: much faster loading, save states for sms, nes core, better price, DRM free updates, regular size, RTC for save states logging, USB for devs

I will admit the SMS save states are cool, though I get that on the Master ED X7.  There's still PLENTY of SegaCD or SMD specific questions to answer though on this.  Cart shell size means nothing to me, though I kinda like the SVP sized MegaSD shell. 

Takeaways from the video, well unlike most, I couldn't give one iota about NES emulation.  I mean come on, seriously?  It's a SEGA console, and who here doesn't have an NES?  Also, the menu, come on Krikzz!  Why are you using the same atrocious text-based menu in this thing?  Granted the MegaSD's can leave a lot to be desired but at least it's not just text.  Lower price is probably the biggest appeal to this.

Yes, the Everdrives have always been quite affordable compared to other quality flashcarts. I kind of agree with you on the NES, but I'm also not complaining. If it got a powerful FPGA it might as well be used for other things than the Mega CD.
I also prefer the black Mega Everdrive universal cartridge.

If the Pro will have everything the X7 has, it seems a much better deal than Mega SD. But I'm not sure about the compatibility for the X7. Anyone that knows what games aren't supported for it besides Virtua Racing?

Mega SD
Price: €232 (expensive and usually out of stock)
Region free: Yes (MD, Mega CD and games, electrically and physically)
Cartridge compatibility: Supports all mappers and save types for MD, 32X and SMS (so 100% compatibility, not sure I believe that)
Mega CD compatibility: (doesn't say)
ROM memory size: (doesn't say)
RAM memory size: (doesn't say)
Save states: 8 slots, MD cartridge games only
Cheats: MD cartridge games only
In-game-menu: MD cartridge and CD games
Other features: Mega CD RAM cart (per game), SMS FM Unit, MD+ support (MSU-1-like thing for MD)
Other note: Updating is a hassle and tied to the serial number of each cartridge.

Assuming the Pro is like X7:

Mega Everdrive Pro
Price: $199 (expensive for an Everdrive)
Region free: Yes (MD, Mega CD and games, electrically and physically)
Cartridge compatibility: SRAM and EEPROM saving and at least some mappers supported
Mega CD compatibility: (still unclear)
ROM memory size: up to 16MB
RAM memory size: up to 256kB
Save states: MD cartridge and SMS games (not sure about CD games)
Cheats: (not sure of details)
In-game-menu: MD cartridge, SMS cartridge and Mega CD games
Other features: Mega CD RAM cart (per game), SMS FM Unit, USB port, RTC, hassle-free updates, FPGA NES clone, SMS pause button, "Mega Key", supposedly "much faster loading" than Mega SD

Title: Re: Mega ED Pro

Krikzz will probably allow for open source menu's like ED64, SD2SNES anyway, but I'm just saying, why not change it up, do something a little more polished?  This is supposed to be the "Pro."  Obviously the SMS IGM/Save States are an advantage, but to me the price and availability will make the difference for MED Pro buyers. 

One thing I would give Terra Onion credit on is that their game compatibility, and just general testing is thoroughly done PRIOR to release.  Yes they have firmware updates, but aside from that SSD3 audio issue, the MegaSD pretty much does as advertised on the box.  Now contrast that to this forum as it is, overflowing with problems on the N8 Pro alone, which has been out for quite some time now.  Yes, Krikzz seems to get to the bottom of most of these errors in a reasonable time, but it's still a minus.  Terra Onion normally produce a traditional retail product that doesn't need a years' worth of further development.  The MODE *seems* like a truly finished product for instance.  Whether that is the truth is another story, as there's so many optical disc dumps out there to cause havoc.  So while Krikzz pricing is 25% lower, you're still receiving a homebrew product in need of additional dev and lacking a finished menu.  There's a tradeoff.
Title: Re: Mega ED Pro
Post by: phoenixdownita on June 14, 2020, 07:13 AM
Not sure it's the same Terraonion we are talking about.

Some of their products are good some were rushed and caused a lot of drama.
Maybe they have learnt and the last wave of products is finally stable with no weirdness at launch.

Wrt to MegaED Pro I expect all of the features of X7 + MegaCD support ... what degree of compat I do not know ... and we'll see how it goes. To be sure Sega is the platform of preference for Krikzz (he said so himself many years ago) so we may see fixes coming relatively quickly.
If the final price is right I'm in (I heard 199US$ but we'll see how resellers would fare it) ... I bought MegaED v1, v2 (X7) and I see myself getting the Pro ... I still have both my v1 and v2 around as I have more than one MD/Genesis, so I kept the old v1 too (I don't actually need SVP, SMS FM support ... as for that I have v2 plus original VR and original JP SMS .... I am set one way or another, but I do like that krikzz closed the gap).

I own both a Mega/SegaCD 1 and Mega/SegaCD2 (for my MD1 and MD2) but they are getting old, temperamental and may as well put them under moth balls.

I was in no hurry for the MegaSD so this announcement of Mega ED Pro is welcome  ... and I like the spartan char only menu ... reminds me of CLI/terminal ;-)

Even if some very simplified MCD core fits in smaller x7 fpga then there is still limits related to memory bus bandwidth.  X7 has single dedicated memory bus, but PRO has dedicated bus for every memory chip, 4x total. Also MCD require CPU for cdd handling and x7 does not have one

SRAM support for SSF mapper was here from day one on Mega EverDrive, evern Mega v1 supports it. Extended SSF mapper specification was made specially for using Mega EverDrive possibilities. Not sure if it just typo, but you should use 0xA130F0 (not 0xA130F1) and word access when using this register. http://krikzz.com/pub/support/mega-everdrive/pro-series/extended-ssf.txt

I realize this is probably a dumb question, but I have never owned an EverDrive and I'm still trying to understand something about save game support.

It has been stated that NES games will not have save state support.  With that being the case, does that mean that it is not possible to save NES games at all?  Or would they still be able to use native game save functions in games that allow for saves - Final Fantasy, Zelda, Tecmo Super Bowl, etc.

Similarly for Sega CD games, will it be possible to save games that supported saves, even without save state support?

Thanks for your reply.
Its is $A130F1 - Regular games uses this reg to access SRAM.
I have followed the SEGA Doc (see attachment) about bank switching. Where registers use odd address.
I have both official Everdrive MD and X3, but if I did not anything wrong in a test with Everdrive I get the bank 0 remapped when using $A130F0 and not SRAM Access which crashed the game due to vectors getting remapped.

I have made a hardware ( https://www.neto-games.com.br/hardware/sonic_delta_40Mb_hardware.php ) based on Sega Doc and it works. But if I can get it working in Everdrive is a great addition to, because is more easy writing to SD, than burning EPROMS when tests in real hardware is needed.

Compatiablity on the MegaSD, I've tried most games on it. Particularly some problem ones (that don't work to well with consoles, emulators, and the like) with unlicensed game, some strange mappers/copyright protections such as Beggar Prince. THese all work just fine.

There is still some work to get some of the Mega/Sega CD games to work, or improve on them as some have some bugs IIRC, dound cuts out, or other graphical issues.

I use a Mega SG so I can't guerentee how things will work on original hardware or not.. But i've heard some problems I've encountered were most likely to thee Mega SG, and indeed many of those got fixed with later firmware.

I haven't hit any problem with any SMS game as far as I know...

RTC for save states logging

What is this exactly? How does it work, how is it an improvement?
Title: Re: Mega ED Pro
Post by: nuu on June 16, 2020, 01:59 PM
RTC means Real-Time Clock. A clock and calender that runs on a battery at all times. Probably for doing time stamps for the save state files. The improvement is, besides letting the user knowing the age of the file, that it can have many files and overwrite old ones perhaps. It would be nice if homebrewers also has access to the RTC.

Ok compatibility is probably very close to 100% then (there's always that weird little game that has some obscure hardware that everyone forgot about and will not work in flashcarts or emulators as a result). The Mega Drive cartridge situation isn't as complicated as the NES mapper hell for example, so compatibility is easy.

From the Pro manual it looks like the Pro does support everything the X7 does. And it has level translation for all lines (unlike the X7). That's it, I'm picking this up!

Me too, currently the only thing that stops me is that it seems to have problems with Japanese SMS and Mark III and will not work at all on SG-1000/SC-3000 (from what I can tell by googling). That and that there is no 44-pin version of it.
Title: Re: Mega ED Pro
Post by: Galron on June 16, 2020, 04:27 PM
I know what a RTC is I was wondering how that helps with save logging...

Is it able to fix the sound issues, where sound cuts or glitched up after a reload of a save state on hardware (because under normal circumstances there is no way to save sound system directly)? Cause that would be rather impressive...

I forgot to mention one of the reasons I've wanted it was because I wanted to be able to do save states on SMS games. I'm also curious how the simulated YM chip on it sounds, as I use MegaSD, and hopefully its compatible with it.... With regular SMS you'd have to do some tweaking to the system, and add in the YM2413 FM sound module?

However, I've also read that the save states feature might not work too well on a MegaSG...

Hmm, interesting, didn't seen it before. Seems sega did never used both bank switching hardware and sram remap to upper area at same time, only one of two features been used in commercial games as far as i know. As example Beyond Oasis used only sram remap feature or Super Street Fighter used only rom banking feature. As for EverDrive i tried your hack while ago and it didn't worked because game wasn't recognized as SSF mapper, you should put "SEGA SSF" in rom header instead of SEGA MEGADRIVE. After this fix i can ran the game but without saves due the lack of eeprof in ssf mapper. I wonder if you can detect everdrive ssf mapper and use sram instead of eeprom for saves? It would provide compatibility for older carts like edmd or x5/x3 where is no way to implement eeprom extension.

Thanks again for the reply. I am using regular SRAM ( which is more easy to handle at code ) not EEPROM. For test, If I cut some levels to down game size to up to 32Mb, I get the Everdrive working with SRAM.

Compatiablity on the MegaSD, I've tried most games on it. Particularly some problem ones (that don't work to well with consoles, emulators, and the like) with unlicensed game, some strange mappers/copyright protections such as Beggar Prince. THese all work just fine.
There is still some work to get some of the Mega/Sega CD games to work, or improve on them as some have some bugs IIRC, dound cuts out, or other graphical issues.

Is there any particular games which you can remember? I'd like to look closer on them using mega-ed.

As far as i can see most of modern MCD cores/emulators uses simplified Mega-CD implementation. During MCD research i did made small test tool for check real hardware behaviours, because sega docs isn't detailed enough for building accurate core. If you ran this tool on Mega-SD or with emulators you will see that almost all tests fails. Checking how it really works probably taked largest part of project time.

Do not forget to backup your saves before than run it.


Thanks again for the reply. I am using regular SRAM ( which is more easy to handle at code ) not EEPROM. For test, If I cut some levels to down game size to up to 32Mb, I get the Everdrive working with SRAM.

I can force SSF mapper for your game, but carts with one time programmable fpga like x5 and x3 still not be able to support sram in way how you using it. May be you could include simple check to detect what type of mapper used and then use supported banck switching model?

Me too, currently the only thing that stops me is that it seems to have problems with Japanese SMS and Mark III and will not work at all on SG-1000/SC-3000 (from what I can tell by googling). That and that there is no 44-pin version of it.

I forgot to mention one of the reasons I've wanted it was because I wanted to be able to do save states on SMS games. I'm also curious how the simulated YM chip on it sounds, as I use MegaSD, and hopefully its compatible with it.... With regular SMS you'd have to do some tweaking to the system, and add in the YM2413 FM sound module?
Only if you have an export SMS, it's missing the YM2413 so you have to do a hardware mod. The original FM Unit is an external accessory (quite expensive now) for the Mark III only which adds the YM2413 to it, and the Japanese SMS got the YM2413 built-in from the start. Japanese SMS also has a more forgiving BIOS so that it can play both export SMS games (with an adapter) and SG-1000/SC-3000 games, while the export SMS can only play export SMS games due to region protection.

And it has level translation for all lines
What does this feature mean?
A few years ago, some older Everdrives were criticized for having insufficient voltage translation between 3V and 5V parts (although the situation was probably not as bad as it was first given the impression of). The Mega Everdrive X7 is the last Everdrive still in production that seemingly doesn't have sufficient level translation for all control, data and address lines (the X5 and X3 do though). From pictures it looks like the Pro has this though, so the criticism will probably be history with the release of the Mega Everdrive Pro.

Oh ya there is currently an issue with games with large size save files apparently on some systems. But that is something they are promising to fix in a later firmware update.... Shing FOrce CD is apparenlty one of these.

Most of the fighting team games have copy protection on them. Some of the Piko stuff has copy protection on it too...

There are supposedly packs that Fighting Team sold that removed the copy protection issue. ANd some hackers have remove copy proteciton from some of the games (Fighting Team and Piko)..

Alternatively there are possibly stuff from the stoneagegamer that has the copy protection already removed, but I haven't tested those in emulators to check for sure.

Obviously there was also Pier Solar which had its own issues, but you have shown you have included that in your compatiblity.

Generally speaking there is no issues with any piko roms buyable thorugh Steam.

As for the CD games one of the fighting games I can't remember which has issues... ANd I think Shadowrun CD is said ot have issues... Of course some of this might have to do with MegaSG issues as well, but I don't have actual sega original hardware to test on. But I think there is a list of issues up on the internet somewhere, possibly through the terra onion forums.

So I'm gonna assume this  probably isn't an issue for Terraonion, and Pro as far as things go. According to them they were very careful to keep the voltages within the margins of safety. It draws less then the Virtua Racing cart.

Also another difference between how Terraonion and Krikkz does things, is that apparently MegaSD saves instantly and doesn't need a battery.  It just checks for a save and directly sends it to the microSD card and converts it.. I tmight not be 'constant' check to see if the saves exist, but might as well be... The situation though ends up with saves going to the microSD the moment you save, rather than it saving after you change to a different game. If I udnerstand things correctly.

I have made a hardware ( https://www.neto-games.com.br/hardware/sonic_delta_40Mb_hardware.php ) based on Sega Doc and it works. But if I can get it working in Everdrive is a great addition to, because is more easy writing to SD, than burning EPROMS when tests in real hardware is needed.

Hmm, interesting, didn't seen it before. Seems sega did never used both bank switching hardware and sram remap to upper area at same time, only one of two features been used in commercial games as far as i know. As example Beyond Oasis used only sram remap feature or Super Street Fighter used only rom banking feature. As for EverDrive i tried your hack while ago and it didn't worked because game wasn't recognized as SSF mapper, you should put "SEGA SSF" in rom header instead of SEGA MEGADRIVE. After this fix i can ran the game but without saves due the lack of eeprof in ssf mapper. I wonder if you can detect everdrive ssf mapper and use sram instead of eeprom for saves? It would provide compatibility for older carts like edmd or x5/x3 where is no way to implement eeprom extension.

RTC for save states logging

What is this exactly? How does it work, how is it an improvement?

It helps manage your save files. Using timestamp you can easily found most recent one for example. Save file timestamp shown right in in-game menu
(https://i.imgur.com/Tra1usV.png)

Cool that timestamp thing is pretty cool idea.

I really haven't had a problem telling which save states are which on the MegaAD and there are only 8 of them, and I generally only use 1 or 2 of them at at ime anyways. But date system is cool...

Plus I assume if indie developer wanted to have  a game that used RTC, that woudl be available too?

Thanks. If you can do this and add full support for future versions like X7 will be fine (some friends has the X7 version). In some tests, I could see that the Everdrive OS is remapped to high addresses and this can be used to check if game is running over Everdrive and call appropriate routine.

Do you happen to had those annoying feel due the using different charger type by the electronics manufacturers, especially in the past when each on had their owns standard? This is that case. I think MD+ does not have advantages over mcd mode1, actually mode1 is more powerful and flexible.  Also mode1 can be used with real mega-cd, while MD+ only for premium flashcarts. Seems like at the moment only TO trying to push MD+, if this thing will ever become very popular i will be forced to implement it, but i hope world will stay at "single charger".

Mode 1 is very inefficient, and doesn't support track fading or looping, so you can get rid of unnecessary audio and prevent bloating audio pack releases with optimised loops.

Mode 1 inefficiency means that patches have to include a sub-CPU program, decompress the BIOS (so you have to include that decompression routine in the ROM), copy the sub-CPU program, bootstrap the sub-CPU, and then communicate with it through the ASIC ports. MD+ has all that logic in the cart MCU, so you just need to write commands to a special address and the cart MCU will handle them as if you had set a sub-CPU program.

Just compare the patches. MD+ patches are a couple of hundred bytes. Mode 1 patches are hundreds of kilobytes.

Everything listed like tracks fading and looping supported by mode1, it only matter of mcd driver. Even interfacing can be as simple as MD+. Also you don't even need to use CD bios, few kilobyte sub cpu driver can do all work.

Although I don't know the details, I also think a MSU-1 variant for the MD is a strange invention when it already has CD hardware. If it really reduces the size of the patches and has more features it might be defensible though.


So I'm gonna assume this  probably isn't an issue for Terraonion, and Pro as far as things go. According to them they were very careful to keep the voltages within the margins of safety. It draws less then the Virtua Racing cart.
No it's not just about power draw, it's about translation of logic levels (voltage) between parts. The SD card for example is a 3.3V part and is not tolerant to 5V which the MD is using, and the FPGA might also work on 3.3V only. So it's necessary to convert the communication between the 3.3V and 5V parts so that each part works with its expected logic level. Many pirate and bootleg carts from China (but not any official Everdrives) are skipping this part entirely and doesn't even have resistors to limit the the current, which means they are potentially dangerous to the hardware (although this varies a bit between different types of hardware). I have no idea if Terraonion's stuff are correctly built or not though.
Soon someone might post a reassuring video from BennVenn (who is in the Flashcart business for the Game Boy) where he "proves" that all pirate carts are totally safe, but I'm quite sure that that statement simply is not the truth. This is a hot and infected topic with lots of business interests and probably personal feelings involved.

The NES doesn't use the Mega Drive hardware, it's basically all in the FPGA. You can add any number of backgrounds to it if you want, but it would no longer be a NES by definition. It would be a new system.

I may be dense, but I am new to this, and the manual needs more detail or examples to explain how to name the files.

For example, I have Dracula Unleashed.  The bin files are named "DRACULA UNLEASHED CD1.bin" and "DRACULA UNLEASHED CD2.bin".  Will those work, or does it have to be the number by itself at the end?  In other words, does it have to be "DRACULA UNLEASHED1.bin" and "DRACULA UNLEASHED2.bin"?

Post by: KRIKzz on June 28, 2020, 12:52 PM
Only single bin+cue supported. Redump multi-bin images can be be merged using this tool: http://krikzz.com/pub/support/mega-everdrive/pro-series/cdfix/
Just put cdfix.exe in folder with cd images and run it. Works for mac also with mono runtime.

as for multi disk naming: disk names should ends with number and all disks should be stored in same folder, this is the only requirement.  xxxxxx1.bin, xxxxxx2.bin and so on
each disk should have separate cue.
no limits about sd size. Biggest i used was 128GB

You just have to merge the WAVs into a single bin.

MP3 should be avoided because it's a lossy compression. They are basically bad dumps.

How do I merge into a single bin and cue when some games are ISO and many mp3? some are multiple bins etc?

MP3 isn't supported. They'd need to be converted to WAV, but as nuu said, these rips are to be avoided.

There are programs you can use to convert multi-bin to a single bin. Binmerge is one.

Sorry if it sounds dumb but when it comes to MEGA-CD files i'm hopeless at understanding this stuff.

Post by: Sarge on July 02, 2020, 02:33 AM
I would also assume you could mount using a virtual drive like MagicDisc or DaemonTools and then re-rip to a single BIN/CUE. Lots of ways to make it all work.

so i want to get a mega everdrive pro asap. are there compatibility issues with any cd games?
 i think i read that two games are not working but i can't find that post anymore. i think the v2 model genesis/sega cd v2 has incompatibility with 2 cd games if i'm not mistaken. i'm not sure if it was caused by the genesis v2 itself or the sega cd v2 or both. i'm wondering if the two games that will not work for mega everdrive pro are those same same games?
 the mega everdrive pro only supports single merged bin files which is fine but some of my sega cd collection are in clone cd img format. they are not in multiple tracks though but single img files with cue. does this format work with mega everdrive pro or does the format have to be bin/cue only?
 maybe the clone cd image files can be easily converted to bin/cue somehow without burning and re-ripping or mounting to virtual drive and re-ripping.

The only feature I would want that this does not offer is the MD+ but KRIKzz has covered that already so we can only hope there is enough demand for it from the public.

How are mp3 files damaged? That's the standard red book audio format, mp3. It's usually

track 1 ISO
track 2 mp3
track 3 mp3 and etc. And to make it work on an emulator you just cue the entire list.

Changing them to bin doesn't work on Kega Fushion neither does WAV. So hearing everybody say that bin/cue is the only way to play Mega CD games on the Mega EverDrive Pro sounds confusing, seeing that bin/cue files do not work on a real game disc or an emulator.

Certainly not. Standard redbook audio when converted to a file is a 44.1kHz, 16-bit WAV file @ 1411kbps. MP3 is all those except it's encoded at a maximum of 320kbps. Compare 1411kbps with 320kbps. It's compressed by more than three quarters of it's original quality. Granted, the safety overhead in 1411kbps is quite large, and MP3 filters out frequencies that are unneeded and that are mostly inaudible to human ears, but it still filters frequencies and is what is called a "lossy" format.
Title: Re: Mega ED Pro
Post by: Sarge on July 04, 2020, 12:20 AM
The real problem is repeated degradation - someone takes an MP3 version, puts it to CD, then re-rips to MP3 again. Yes, in most cases, the differences in MP3 if encoded at the highest rate are barely noticeable, but they are there.

Okay i'm not arguing with you or any of you, you guys know more than me on this matter and I apologise for sounding dumb, i'm listening to you and I understand but I personally cannot get WAV files to play on an emulator, example is Kega Fushion (it's the only emulator that attempts to play Mega-CD games, Gens + won't even load) and the damn thing only accepts ISO and MP3 cued into a single file, if they're seperated the game usually has no music. I get an error message if it's a WAV file and some games come in IMG files that can't be extracted as someone else pointed out on this thread and they don't play on emulators.

I'll break it down in points:

To my knowledge and experience

Emulator - accepts only ISO and MP3 or ISO/MP3 cued.

Real Mega-CD/SEGA-CD attachment with files burned to CD-R accepts ISO, MP3 ISO/MP3 cued and IMG files that extract once written onto disc.

If and when I ever get a Mega EverDrive Pro i'll certainly try changing them to bin in a cued file. Makes sense actually seeing as cartridges take bin files with the Mega-CD core implemented.

Title: Re: Mega ED Pro
Post by: nuu on July 04, 2020, 05:32 PM
You are not dumb, I think most people aren't aware that MP3 is a format that has data removed, and that it's a bad format for CD rips such as used for game preservation. That's why I bought this up when someone mentioned MP3.

Kega Fusion and Gens are old emulators not updated in a long time and are probably the only ones that supports MP3. It's unfortunate that Sega systems doesn't have as many good modern emulators as NES and SNES has.
If the emulator you use requires MP3 and you only have 1:1 CD rips, you can just convert the WAV, FLAC, IMG, ISO or whatever you have to MP3, but keep a copy of the original 1:1 rip somewhere safe and don't touch it.

The Mega CD disc doesn't have a file system (burning a data CD with BIN, ISO, WAV or whatever will not work), it uses CD tracks just like PC Engine's CD system. The first track is a data track with the game program on (this is the BIN file in a BIN+WAV rip) and the rest are red book audio tracks (the WAV, FLAC or MP3 files). BIN, ISO or IMG doesn't matter, as long as it's a 1:1 rip of the CD you can always burn it on a CD-R and it should work on a real Mega CD. You may just need the right tools to do it.

When burning a CD-R you can technically use MP3 for the audio tracks and the game might even work at first, but the problem is that they are not exactly the same as the original digital data on the original CD, and that is a recipe for trouble that we just don't need. Ripping CDs and converting them to MP3 is a careless way to rip game CDs on, and not suitable at all for preservation. It was popular long ago when internet was slower and HDD space was more expensive, but it's something we tries to leave behind us.

MP3 is fine for music files that you just listen to in Winamp or an MP3 player, as long as your ears accepts the quality loss and you don't care that they are 1:1 with the tracks from the CD. But even here there is a problem, like Sarge said, repeatedly converting to or from lossy formats degrades the sound and the quality loss get more and more audible, for the same reason lossy image formats like JPG degrades if you keep saving them in that format when doing image editing.

i have been running mega/sega cd games using neogenesis for xbox original which again uses iso/mp3 format.
 i downloaded the entire set again a few years back and most the games are in iso/wav format which can be converted using the tool krikzz posted but the img clone cd images i don't know about.
 maybe i will just re-download those ones in iso/wav format to be sure. i did not get a reply about the img format so i gather nobody has tried using these images on the pro.

Just to clarify: Since both the Mega Everdrive Pro and the "other one" can run 32x games and Sega/Mega CD games, but not games that require both, do all Sega/Mega CD games enhanced with 32x also have versions without 32x requirement? I was checking the 32x games list at Wikipedia (https://en.wikipedia.org/wiki/List_of_32X_games) and by following these games links, they all seem to have both Sega/Mega CD versions and 32x Enhanced versions:
- Corpse Killer
- Fahrenheit
- Night Trap
- Slam City with Scottie Pippen
- Supreme Warrior
- Surgical Strike

EDIT: Sorry for the dumb question. As indicated in the Sega Retro (https://segaretro.org/Sega_Mega-CD_32X):
Quote
Six games were released that require both add-on units in order to be played. All of these titles are full motion video based games, which were previously available as standalone Mega-CD games, and later had their FMV assets upgraded to take advantage of the 32X's improved graphics. As such, all six were released on CDs, with the cart slot of the 32X being unused during gameplay.
So yes, all CD games can be played (if compatible), except for the 2nd version of the 6 above which requires both addons. Nice!

Simply awesome! I prefer the Mega Everdrive Pro's regular cartridge format over the Mega SD's virtua racing cartridge format, the only downside was the image format support that now seems fixed.

This is just a personal taste and in no way a deal breaker, but I really like the Mega SD menu small window that shows snapshots of the ROMs, and I hope that the ED Pro could add this option in the future, plus a snapshot of each save file instead of a full screen preview. Even better, an option to switch between snapshot image, cartridge image, and game box image. Now THAT would make the Mega Everdrive Pro even greater!

 it would be a nice touch to have box art support. the jaguar gamedrive looks great with the boxarts in menu but the lack of cosmetics with krikzz products would never be a deal breaker.
 for me quality and functionality is the main thing.

It boots to the menu and loads genesis roms just fine. It also detects the 32x hardware on the "info" screen.

Has anyone in the United States received their order yet?  My shipment was processed in Kiev on July 5 and I haven't seen a tracking update since.  I know shipping is slow right now, but at what point should I start to get concerned?
Wait at least 5 weeks.
I'm almost to 4 weeks since the last tracking update, so I'm getting increasingly concerned now.  Has anyone else in the USA received theirs?

I ordered mine on 6/30, got an email that it was "sent" on 7/11 and I received it on 7/29... but mine seems to be faulty.   :(

Post by: oakleez on August 04, 2020, 02:59 AM
Figured out my issue.  It was due to the Mega Amp 2.0 inside my Genesis 2.  Apparently, for whatever reason, it draws too much power to allow the Mega Everdrive Pro to play 32x games.  Genesis and Sega CD worked fine, but it must have just not had enough juice to power everything in my configuration.  I switched to a different Genesis (model 1 without Mega Amp) and now 32x works fine.

I just got new Mega ED Pro and Genesis/SMS stuff is working fine but I have some problems with Sega CD games (freezes when loading game). Can someone tell if I have done everything right or did I miss something?

This is what I have done:

1. Downloaded and unzipped latest firmware (4.02)
2. Moved Sega CD bios files (EU, US, JP) in /MEGA/bios folder
3. Renamed bios files as mcd-us.bin, mcd-jp.bin and mcd-eu.bin
4. Dropped some Sega CD games in their own folders
5. Started Sega CD game

The hardware I am using is Mega SG with latest firmware.


1. Try another sd card if possible. At least two people reported about problems with sandisk 128GB card when using cd function. However i bought such card and seems everything fine in my case.
2. Make sure that power supply is powerful enough, also you should use good cable for powering this all. Thin cables designed for 500mA current may cause faults. Peak power loading comes in CD mode

Figured out my issue.  It was due to the Mega Amp 2.0 inside my Genesis 2.  Apparently, for whatever reason, it draws too much power to allow the Mega Everdrive Pro to play 32x games.  Genesis and Sega CD worked fine, but it must have just not had enough juice to power everything in my configuration.  I switched to a different Genesis (model 1 without Mega Amp) and now 32x works fine.

Are you sure it not just an problem with 32x contacts? Sometimes i must reinsert my 32x few times to make it work properly.

Is there maybe a problem with FAT32?

Got mine today. It works great so far. Using my Sandisk Ultra 128 GB sd card formatted to exFat. No issues with Sega CD.
Title: Re: Mega ED Pro
Post by: LeoLion on August 06, 2020, 12:30 PM
I've had mine for 3 weeks now and it works great with my Mega Sg.

I also use a SanDisk Ultra 128gb micro SD card and have had no issues, they are formatted to exFAT by default.

I had a handful of Mega Drive games not load on my Mega Sg due to the reset instruction, but the updates by Krikzz have since fixed these problems.

The only 2 Mega CD games I've had problems with are Sewer Shark, which had slight stuttering audio using a USA rom, but this doesn't happen when I use a PAL rom.  The other is Double Switch, which has really bad stuttering audio no matter what rom I use, but apparently this is a Mega Sg problem.
Title: Re: Mega ED Pro
Post by: KRIKzz on August 06, 2020, 01:39 PM
Sewer Shark labeled  "Not for Resale" should work fine, it is later version of game with fixed audio. Early game build has the same stuttering audio glitch on real mega-cd2 and on mega-ed, but in same time works fine with cdx.
Double Switch works fine at original console, seems problem appears only at MegaSg
Title: Re: Mega ED Pro
Post by: LeoLion on August 06, 2020, 02:18 PM
Thanks so much for the reply.

I didn't know about Sewer Shark (Not For Resale) version, I will try this version later after work.

Just out of interest, do you know why Double Switch has the stuttering audio on a Mega Sg?  I am not complaining, just curious as to why it only happens with this game.

Keep up the amazing work!

You'd probably have to ask Kevtris. Sega CD on the Mega Sg can be hit-and-miss, some older firmwares work better than newer ones for specific games. But at the same time some games like Chuck Rock don't work well in older firmwares but do in the newest, so your results may vary depending on the firmware version you're using.

No. I'm actually running it off of my sega nomad. I haven't played a lot of genesis games, but it works in Spiderman Maximum Carnage just fine so it got me curious. I'm also running it off of the 4.03 firmware.

Not all Mega Drive/Genesis games are compatible with the in game menu. The manual states “In-Game menu does not work for games which do not use v-blank handler”, so it’s probably due to that. The only game I’ve come across so far that isn’t compatible with the in game menu is Asterix and the Great Rescue.
Title: Re: Mega ED Pro
Post by: LeoLion on August 06, 2020, 11:40 PM
@KRIKzz I can confirm that Sewer Shark (USA) (Not For Resale) version for the Sega CD does indeed work absolutely fine without any audio stuttering on my Mega Sg, so I highly recommend people use that version above all others.

I've updated the firmware on my Mega SG and changed SD cards to a Samsung EVO 256GB. I've also tried a couple different Sega CD bios files but no luck so far. What is the recommended US bios version?

i wonder if the rev 1 (rev a) version of sewer shark also has the audio glitch fixed. the not for resale version has 3 dumped versions for redump. rev b reb b alt and rev b alt 2. anyone know which one is verified good?
 is the issue with the original sewer shard usa version a problem just with megadrive/genesis 2 or does it play fine with an original megadrive/genesis?
 i read a long time ago that the mega cd 2 has compatibility issues with 2 games but it was ages ago and i can't remember what games. not that this should be an issue when using mega everdrive pro. more of a curiosity.
 i held off re-buying a mega cd for a number of years in hopes of sd solution but if i were to have purchased a mega cd it would have been the original phat version to avoid that incompatibility issue.

I know it's not Sega, but would rock to see other systems (GB and GBC, maybe GG find a way around that color pallete limit) and more time spent on the NES core. Maybe even release the source for it and lets others work on it.

Otherwise it rocks. When I received the Mega Everdrive Pro I sold my Mega SD and am never looking back. Though, wish we could figure out how to convert saves between the 2 carts. The save splitter app, only works with internal ram and can't convert ram cart saves. Also, not having any luck with Genesis/Megadrive games. Thankfully Sega Master System games are drag and drop compatible without conversion.

You’ll definitely want your multi disc games each in its own folder, and ensure that the cue and bins are named properly (apart from the disc numbers). I only had to do some manual renaming on the Scottie Pippen one, to get rid of the character name, to make the auto disc switching work. Speaking of which: it simply cycles through the discs in sequence, so going from disc 1 to disc 4 takes a few clicks. But it works perfectly!
Title: Re: Mega ED Pro

ok cheers guys. i gather that folders within folders works ok. for example cdgames/sonic cd/files?
 regarding needing the disc number being at the end of the filename is it ok if the disc number is inside()
 i usually name my files something like this
 sherlock holmes (cd 1).bin
 sherlock holmes (cd 2).bin
the above is not the actual filename but an example. would this be ok or does the () cause issues?
Title: Re: Mega ED Pro
Post by: peterlanders on August 30, 2020, 06:50 AM
As long as the final digit in the name is the disc number you’re good.

As for folders in folders, that’s fine, but make sure all the cue/bin files for a single version of a particular game are kept together in a single folder. MEP will offer to play the game when you select the folder itself.

Be sure to download the manual, it explains the rules at least to a certain extent.

You're right, I completely forgot! The Mega SD is the bloated one :)
I wonder if there will be a Black Friday discount this year? I bought my Everdrive X5 directly from Krikzz but now it's only available through authorized dealers, which I don't know if they'll follow the same discount. I would buy the ED Pro in a heartbeat and then sell my X5 at a later date.

Krikzz has said that there will be the Black Friday discount and Everdrive.me is essentially the same as the old Krikzz store. Stoneage Gamer usually does the Black Friday pricing and last year Krikzz lowered the prices on Amazon for Black Friday if I remember correctly.

It will work. Disk number should be last number in the file name, also all files should have the same name except disk number. This is the only requirements.

@Krikzz - thanks for responding to this. so by last number in the filename the ) at the end does not make a difference at all? the mega ed pro only looks for the last number no matter where it is located in the filename?
 there is another issue i would like you to clarify. someone posted here that running ntsc sega cd games on a pal console will have issues even if you use 60hz setting with region modded system due to the actual console hardware still being 50hz speed. have you had experience with such issues.
 if it is the case that there are timing issues when running ntsc cd games on a pal megadrive then would installing a dfo mod fix such issues?
 i know the dfo mod fixes these issues with a ps1 but i'm not sure if the dfo and mega everdrive pro would work well together and if the dfo would be able to detect game hz speed since the games are launched from the mega ed pro menu and would the dfo still be able to detect change in game hz this way or does the dfo only detect game hz speed from boot?
 i hope i explained the dfo question ok. i was finding it hard to know exactly how to word it sorry.
Title: Re: Mega ED Pro
Post by: KRIKzz on September 17, 2020, 07:03 PM
Simply system seek decimal numbers in the file name and last of found numbers will be recognized as disk number.
As for pal games on ntsc systems or visa versa: you need actual 60hz for ntsc games or 50hz for pal, just an region changing mod is not enough (megakey can change regions without any mods, but not actual frame rate). CD games is pretty sensitive to timings and lot of them will not work properly on different region. I don't know how dfo mods dealing with auto region switching, so at the moment i can't say something about this stuff.  By the way, there exists one interesting solution which allow to switch console region, frame rate and even overclock the cpu, and this all working via gui menu called from controller using hot-key combo. It called MEGASWITCH: https://youtu.be/DOXWpRxZNPs
Title: Re: Mega ED Pro
Post by: butfluffy on September 17, 2020, 10:49 PM
thanks for the response Krikzz.
that megaswitch mod looks great. the dfo does the same sort of thing but only has one function. it detects the hz game signal and sets the timings to ntsc or pal.
 i already have switchs to set 50/60hz and region so i only need the dfo and it is cheap.
 i will need to find out if the dfo auto detect is somehow not going to work because of the mega everdrive pro os.
 hopefully the dfo will detect the change in hz signal at anytime and not just on bootup if that makes sense.
 i will ask about.

Hi Krikzz, I have a Pal Asia (Japanese plate with capacitance) with switchless (it unlocks the real 60hzs in that model), and it does not matter what region I put, both in Pal, as in the USA and Japan, there are games that music plays  It slows down and does not make a good reading, if at that moment, it pauses, it fixes itself, but if you can't pause and it loads, the game most likely crashes, I already have videos prepared to advertise a product of  $ 200 that you are selling, and it does not work correctly, what's more, you stop commenting on this topic, as well as the jerks of the intro of the popuf mail, why don't you know how to fix it, at least for now, yes, you are charging  while these failures continue.

Check if the Master clock oscilator matches a true 60hz machine.

If it matches the clock of a Pal 50hz system, only pal 50hz CD games will run correctly and only with the vdp setting to 50hz.

Try with an unmodified console.

I played a Japanese final fight on a Japanese console, and on my other Pal Asia console, with microsd Kodak, lexar and 128gb sandisk in exfat format, (in fat 32 almost all games fail), I have passed it three times  on each console with those three cards, on both models, with Kodak, not only did the music slow down, that the end was not seen, just a black screen and background music, with lexar and sandisk, the end looked good, but  the music kept failing in its reading, all this, in both models of plate, exactly the same errors, perhaps the question would be, have you tried to play it with those models?

I just experienced something weird when I started to play Lunar - The Silver Star (Sega CD game, USA). The game started and I watched intro movie, but after that completely different game, Robo Aleste (USA) started to run. In other words the game changed automatically. Robo Aleste was the game I played before Lunar but the console was turned off between these game sessions. However, I think this has something to do with saves. When I played Robo Aleste there was some question about creating new save slot (or something). Does anybody know why this happened and what settings I should check so that this won't happen again?

Thanks for the answer, friend, the truth is that here in Brazil the pro reaches twice as many with third parties, and the library of the sega cd in my view is weak, so my real "ambition" is to have a larger library, and if with the pro would be more of the same since my X7 runs everything, now if the pro runs the 32X without the additional 32x there it would be worth the price that arrives here in my beloved corrupt country.

While the Pro supports 32x ROMs, you still need a real 32x to actually play them. So it sounds like you’ve probably got everything you need with the X7. The NES core on the Pro is really neat, but as @zaphro72 says, it’s just a fun bonus feature, not a substitute for a full NES solution. Many games work really well, but it’s far, far, far from 100%.

Thank you friend for answering, the only games I use on the sega cd are eternal champioms, shining force cd and lunar for what I saw, now if it came 32x in the future I would be extremely crazy to buy it, because my childhood dream was the complete library of mega.More years KRIKZZ Launches Mega Everdrive PRO PRO SUPER ULTRA DLC .Thanks my friend

I'm having an issue trying to boot up Heart of the Alien. Instead of going to the Sega CD boot screen and then starting the game, it goes to a different colored version of the boot screen that is completely frozen. It used to do this on Sonic CD as well, but that seems to have been resolved with a later bios version. I've used this same ISO on an emulator and it worked fine. Curious if anyone else has seen this?
