Mega EverDrive / Re: 60hz PAL console issues with Everdrive Pro?

The game does have quite a bit of slowdown at 60 Hz.

Mega EverDrive / Re: Mega EverDrive X3 Garbage pixels in some games
« on: December 19, 2020, 09:44 AM »
It's not the Everdrive, it's a hardware bug. There's nothing to check and there's nothing to fix. Our memories are not reliable for details like these, especially when you're comparing a recent experience as an adult with upscaled RGB on a modern display to a 25-year-old experience as a kid with composite or RF on a CRT that likely cut off the affected portion of the image (as I mentioned, efforts were often made to hide the artifacts by taking advantage of the limitations of displays used at the time).

For reference, the Mega SG by Analogue has an option to turn CRAM dots on or off depending on the level of authenticity you want. That's about the closest thing you're going to get to a real Genesis without them.

They're just CRAM dots. If I recall correctly, every time a new palette entry is swapped in, a dot (or multiple dots) will show up somewhere on the screen, so it's simply a matter of whether or not the developers have tried to move them to a less conspicuous portion of the screen. This will also happen with the original carts and has nothing to do with the Everdrive. The Sonic games are well-known for doing this when water is on the screen (they change palettes mid-screen to effectively double the number of colors that can appear at one time), leaving a waterline consisting of these garbage pixels.

The only way to get away from them is to play via emulation.

Maybe for you it's sorted but other people are still struggling with this one game and i'm one of them. I'm having great trouble trying to get this sorted. It's not fixed and I don't care if this topic is more than 6 years old I can't get Super Thunderblade Game Genie cheats and the RAW equivelant ''Pro Action Replay'' codes to work with this game, I get either a black screen or a red screen when those cheats are put into the game, my PC won't let me run this uCON64 because my firewall thinks it's not safe, besides that it wasn't explained really well, what does it have to be patched with and where exactly does it have to be patched?

Would be far easier if someone could just post the working ROM with all these patches in it for the rest of the community instead of having to jump through hoops over and over trying to work out this stuff.

Are you really just looking for a way to fix the checksum? Just try this (it's specifically made to do nothing but fix the checksum for a Genesis game):

Patch the GG codes into the game and then run that afterwards so you won't get a red screen (be aware that if the extension for your ROM is anything other than BIN, you may need to change it).

Mega EverDrive / Re: Save the current game (Mega CD)
« on: November 05, 2020, 06:16 AM »
Ecco: Tides of Time CD is the only game of the two that has a save feature, although it's not necessarily what you would expect. It automatically saves a password for the last level you reached, so you need to actually go into the password screen to pick up where you left off.

Will it let you navigate the menu with the second controller port? Krikzz was toying with the idea of adding that ability at some point but I don't know if it ever happened. If you don't have the newest OS version I'd probably check it out just to be sure.

Huygens created patches for these games so that you can play them with a Genesis controller:

Two questions regarding compatibility with the "Analogue Mega Sg" in order not to buy something that I would regret later:

  • Are "Mega EverDrive PRO" and "Mega EverDrive X7" compatible with it?

If you have a Mega SG, you don't even need an Everdrive. Unless you really need save-states or Sega CD support, just use the jailbreak firmware which lets you load ROMs.[/list]

Mega EverDrive / Re: X7/V2 not working on my Mega SG
« on: January 14, 2020, 04:15 PM »
It's everything in the official firmware plus ROM loading from the SD card. As far as I understand it, the jailbreak firmware is essentially official but released in an unofficial way to keep things on the down-low. Check it out here.

I don't have the Mega SG myself, so I can't compare directly, but the only thing I can see an Everdrive possibly having over a Mega SG with the jailbreak firmware is being able to use it as a RAM cart for the Sega CD, but for all I know there might even be a workaround for that.

EDIT: Here's a discussion on the topic:

I can't help you with your specific issue, but you do know that there's "jailbreak" firmware for the Mega SG that lets you run games off the SD card, right? An Everdrive is a bit redundant if you have one of those.

There isn't much else that I'm aware of. Sonic & Knuckles had an extra ROM chip in it for running Knuckles in Sonic 2; there were a half-dozen carts that had extra controller ports built in (Pete Sampras Tennis, Pete Sampras Tennis 96, Micro Machines 2, Micro Machines 96, Micro Machines Military Edition, and Super Skidmarks); and a couple games used bank switching to get around the 4MB ROM limitation (Super Street Fighter II, Pier Solar, and Paprium, if it were ever to be released). You can find most of that info here:

Mega EverDrive / Re: Sound issue when using Mega everdrive x3
« on: October 05, 2019, 03:40 PM »
After having tested as many games as possible on the genesis model 2, most games ran flawlessly. The x3 possibly does not compatible with my genesis 1. One thing I noticed is that  the cartridge itself was rather difficult to be inserted into the gen 1 slot; I had to force it down. On the other hand, the inserting into gen 2 was buttery smooth. could that be the cause?

I don't have an X3, but my MED V1 puts a death grip on my model 1 cart slot too. Other than, though, it works perfectly fine, so I'm sure it's unrelated.

Mega EverDrive / Re: Wonder Boy in Monster World doesn't save (ED X7)
« on: September 19, 2019, 08:21 AM »
Most non-sports games with save systems use SRAM, I believe. Sonic 3 uses it and, if I recall correctly, you'll have a save showing you at zone 1 if you start a new game and reset without getting past the first act. Just don't use Sonic 3 & Knuckles as that may have save issues on an ED.

Mega EverDrive / Re: Wonder Boy in Monster World doesn't save (ED X7)

I am not starting a new thread since I have the same issues as explained above. In detail:

I am attempting to play Wonder Boy in Monster World with my Mega Everdrive V2 (X7) and Genesis model 1, but it does not save. So I would like to know if there is something I do wrong, as some people say that the everdrive X7 now supports EPROM saves. This is what I do:

1 - Start the console. Start the game. No problem
2 - Saving the game in the first "hotel" I can. Continue playing for a few seconds
3 - Reset. So I am back at the everdrive menu, out of the game
4 - Options - Toolbox - Save game ram to SD
5 - Start the game again to see if everything is ok. It is, since on the screen I see the option to continue, and it actually takes me to the place where I saved the game
6 - Turn off the console
7 - Couple of days later. Turn on the console
8 - Select game only (not starting)
9 - Options - Toolbox - Save SD to game ram
10 - Start the game. Only new game is possible
11 - Freaking out for the 6th time

It is becoming pretty frustrating since I feel like I am wasting my time. Any help around???

Have you tried the SRAM hack? Here's a link to the patch if you haven't (you need a program like Lunar IPS to apply it):

Some GG games were basically just SMS ROMs in a GG cart, so that could explain it. I have no idea which games are like that, though. Maybe the extensions were automatically changed to .SMS by whatever ROM checking program they used since they matched SMS dumps.
