That's a famicom not a nes.  Why on earth is the sd slot sticking out the side?  Anyway I'd probably buy this for sure whenever it gets done.  I'm curious what support it'll have, like fds, vrc6 / 7 / whatever audio chip came in the famicom version of gimmisk.

I'm definitely excited about this!  If it comes out as a Famicom cart I'll just have to get an adapter for my NES.  No big deal.  Excited.

hey igor would be able to knock up a 60 to 72 pin adaptor for this? could have it in the shop as a optional purchase for when the cart goes live :D

Personally I think making a famicom flash cart is much better than a nes one.  The famicom slot has pins for upgraded audio, and no stupid lockout pins.
Title: Re: Mysterious cat detected!
Post by: KRIKzz on September 24, 2012, 11:20 PM
I will make two versions, one for nes, and another for famicom. Famicom will be released faster. Release date is unknown at this moment

I mean for people that don't have a NES yet and want to buy one, do you suggest the japanese famicom? the european NES? the US nes2 console? or any console revision is good?
Title: Re: Mysterious cat detected!
Post by: KRIKzz on September 24, 2012, 11:53 PM
Famicom AV is my favourite system. It have good quality, small cartridges, compatible with snes/n64 AV cord. Classic NES visually looks good, but cart slot and plastic quality is poor, also front loader is not handy. Classic famicom is a worst system as for me, joypads is mounted to system permanently, RF output only.
Title: Re: Mysterious cat detected!
Post by: keropi on September 24, 2012, 11:55 PM

I assume the US toploader is a good choice too? it's the same right?
Title: Re: Mysterious cat detected!
Post by: dvd2vcd on September 25, 2012, 12:40 AM
i have a PAL nes...and yes i know the sound quality is garbage but the US top loader has no AV output its RF only so thats garbage...only decent console would be the famicom if you can find one thats in good condition, i think the clone consoles are better but thats my opinion :)

My AV famicom with true rgb and s-video.  The switch at the back switches the console between the default audio circuit and an  upgraded audio circuit.  I hope this cart's going to use ram instead of flash for the game roms but if not I'll buy it anyway.

I did the mods myself.  I found this lovely expensive pcb kit you can order from japan.  The kit is circuits that're custom designed for using a rgb chip in the av famicom, the pcb also contains a custom audio circuit for the av famicom that makes the system sound 10x better.  The reason why I installed the audio switch is because I found 2-3 games that don't sound right with the upgraded audio circuit.  The kit is a lot of soldering and the instructions are all in japanese.  Also I made improvements on the kit I found an upgraded video encoder chip that's pin compatible with the pcb.  I also built a clock dividing circuit so the video encoder colour subcarrier signal is coming from the same clock signal as everything else on the board, this produces better colour in s-video.

Post by: B00daW on September 25, 2012, 04:59 PM
A couple issues and questions, Mr. KRIKzz...

1.) People should probably know that without a modified NES and modified 60-pin converter to route the expansion audio pins they will not be able to use expansion audio with the Famicom cart in their NES.  You could potentially make profit on selling expansion audio converter carts too.  Should be a simple design.  Are you interested?

2.) Will you support the following formats:  iNES, UNIF, NES 2.0, FDS, NSF, NSFe, and NSF2? 

iNES should be deprecated shortly.  I'm working with No-Intro (http://forums.no-intro.org/index.php) to convert over their database to supporting NES 2.0 (http://wiki.nesdev.com/w/index.php/NES_2.0).  The current issue is that dumpers, like myself and others, know that iNES has practically run out of mappers for new obscure unlicensed content and potential unreleased prototypes to be assigned mapper numbers.  Not to mention the EverDrive NES/FC could be a very good development platform and NES 2.0 could be used so developers could use Verilog to code new mappers to the FPGA and assign a NES 2.0 number. :)

Even though FDS is a rip format, it should be supported.  Working to start the more accurate disk image format of FDS to be created and supported in the future.

NSF was supported in PowerPak by a hack.  PowerPak at minimum supports 4KB bankswitching.  The NSF mapper needs 2KB bank switching.  The NSF player by loopy was made by mirroring the 2K into 4K; unfortunately doubling the ROM space.  The maximum PRG space in PowerPak is 512K.  This means the largest NSF can only be 256K; even though the maximum spec for NSF is 1MB.  With PCM being a normal occurrence in NSF composing these days, because of SuperNSF, MuseTracker, and DefleMask, we will soon be reaching the 1MB limit and will want the ability to play back on hardware.

NSF as a format is in the process of being deprecated.  The NSFe format was made to give better track description capabilities.  As NSF is also incomplete in capability as there are many commercial games unable to be supported by the NSF format.  NSF2 (http://forums.nesdev.com/viewtopic.php?f=6&t=7304) was developed by the same author of NSF to remedy much of the issues.  To quote the shortcomings of NSF:

Quote from: Wikipedia
There are some audio drivers that have a play call in the NMI as well as audio code in the IRQ. Since the NSF format currently does not support an additional IRQ address setting, those rips will not play either without extensive modification.

There are only approximately about 40 games that require this function to be ripped properly in NSF format. So, it's unknown as to when this format will be finalized. Quietust has implemented some features of this proposal in his emulator Nintendulator which allows both Battletoads and Battletoads & Double Dragon to play with raw PCM drums. There may be other players that support the watch-dog timer and/or non-returning features as well.
Additionally with IRQ being supported we could finally have some truly synthesized NSFs.  Here are some examples (http://membler-industries.com/squeedo/) of the NES being used at a high refresh rate as a synthesizer.

Which leads to...

3.) Will you work with supporting the ENIO (http://enio.chykn.com/wiki/index.php/Main_Page)? It adds ethernet, USB, and additional SD bootloading capabilities.  Having USB and ethernet with even more additional hardware expansion means possible MIDI input/output and potential MMO games.

I hope I've provided a lot of food for thought. :)

This may come as a surprise but when I started talking among other hardware communities I was given the impression by other retro console hardware developers that your products are often hastily designed and don't take advantage of their full capabilities.

I give you this knowledge in hope that you can use this all to make a product that not only has good reviews but will keep selling and make others very happy.

Prosperity to you, sir.

Post by: KRIKzz on September 25, 2012, 06:10 PM
I would like to respond on question about specifications and supported mapper when development will be near to completion. Currently too early stage of development, cart specification may change few times before than final version will be done. Definately can say that cart will allow to use custom mappers, developed by users. Min bank size 1Kbyte

I'm really curious if this (and your SNES+Genesis everdrives) would work on any of the recently made NES clones? e.g. the Retro-Bit brand, I recently picked up the RES and it got me thinking "hmmm, everdrive?" they also make combo units with NES+SNES and NES+Genesis. Imagine a console made in the past year or so with TWO different everdrives at once?  ;D 8) :D ;) :)

I attached a picture of the three clone consoles I mentioned, I'd really like to know if you get a chance to test any of these as finding a reliable retro console is becoming increasingly harder/expensive, it'd open up a lot more customers for the NES, SNES, and Genesis everdrives too if more people actually had a console to stick it in lol, so lemme know if it's possible and I'll shout the good news from the rooftops :)

Actually reading his posts it sounds like he's going to design the cart so people can make their own mappers.  Which is how the nes powerpak works and it makes more sense.

That's a great project awaited by a lot of people :)

Did you think about a double sided Everdrive ? At one end the Famicom connector and at the other end the NES connector, this way it could be used with both consoles.

PS : When modding fake RGB french NES to output composite, the quality is as nice as the Famicom AV or Sharp Twin Famicom.

Not a bad idea but I'd rather just have the choice to buy one, the other, or even better....both!  You could always just buy a nes to famicom adapter or vice-versa.

I don't get why you'd need both.  You can play english roms on your japanese system with it.  Buy both and show krikzz that you support him like you should if you really want to play on both models for some strange reason.

I support him more than you think and I own all his Everdrives ;)

There's not only Jap and US games ; I'm in France and I think you know that PAL games won't always work on NTSC system and vice-versa.

And a double Everdrive will be great, I mean why make people buy two times the same Everdrive when only the connector changes ?
And people who will buy only one of the two kind of "NES Everdrive" may buy some ugly and sometime dodgy 60-72 or 72-60 adapter.

1)dual famines cart will not fit in famicom shell
2) i dislike super all in one solutions in chinese style, so i will never make something in such style
3) you always must change  shell when you want use another system, so i think that device like this is completelly unusefull
So better to choice one system, or buy pal and ntsc nes or buy both carts

i am getting this for sure! i am tempted to buy the Famicom version when it comes out, but since the Famicom has really bad RF out my better judgement tells me it would be best to wait for the NES version. i just replaced my 72 pin connector, i guess once i get this i can be sure it will never fail since i will probably never remove the Everdrive once i have it set up the way i like. : )

Wow so many chips.  PRG ROM, CHR ROM, SRAM/WRAM, and 2k for name table ram for 4 screen mirroring if the Altera doesn't have enough.  What's the rest?  Looks like RAM for the CHR/PRG ROMS and a Flash ROM for firmware and configuration device/USB blaster .

Oh and welcome to mapper hell!
Title: Re: Mysterious cat detected!
Post by: exdeath on November 02, 2012, 08:34 PM
The best mod for an old NES-101 (top loader) is to add RCA outputs. I am willing to mod others consoles for $40.  I'm located in the USA and it doesn't take me long to have the console modded and on its way back to you. PM me here if you're interested.

Wow Krikzz, can't say I didn't know you were going to make a Famicom/NES flash card. My question is, what size (KB) are the PRG RAM/CHR RAM going to be? Also, are you using Flash ROM again, or SRAM? And finally, what size (KB) are you using for WRAM? The answers would be nice to know. As you already know, another Famicom flashcard is about to be available, and your answers would make a decision to wait much easier.

Those look like SRAM/SDRAM chips. Its best to use RAM for NES because you can reuse the same chips for games that add RAM, 8K CHR-RAM and no CHR-ROM, etc.  So many configuration options for NES carts, RAM lets you do it all with the same hardware




Title: Re: Mysterious cat detected!
Post by: KRIKzz on November 02, 2012, 08:49 PM

Well yeah, NES is dual bus with simultaneous access.  The CPU and PPU have their own independent address/data space and data bus to the cartridge each going to separate ROMs.  That's why the cartridge slot is so big, it's really two cartridges in one.

I suppose you could use a single chip but you'd need some fancy address decoding, buffering, even dual ported RAM for simultaneous access for both PPU and CPU.  It would be messy as hell; better just to use two RAM chips.  Not like 2 x 1 MB is expensive.

Not to mention it would greatly complicate mapper design.
Title: Re: Mysterious cat detected!
Post by: KRIKzz on November 04, 2012, 04:58 PM
Not really hard to use single chip for ppu and cpu, but i decide to use separate ram chips in my design, like in original carts. But when i used my DE1 dev board for prototyping, i used single chip for ppu and cpu, cuz de1 have the only sram chip. I runs sram at 50mhz speed, each odd cycle i latch data for cpu, and each even cycle for ppu.

It's an 8 bit machine but also the most complex cart system there is next to Neo Geo (which are basically all one off custom carts).

Custom audio won't be possible on a NES without mods as the cart slot lacks the audio mix pins.

The EXP pins on the NES cart will probably just be mapped to the FPGA and that's it.  You'll need a single resistor  connecting that EXP pin to the audio in pin on the expansion port to connect it to the cart.  That's it.  As for enhance audio support and quality, it's entirely dependant on the FPGA firmware that somebody writes.

But an FGPA is a digital device (the Cyclone II anyway), it will never sound as good as a real sound chip if there are analog parts involved.  But most audio chips just provide square wave channels and those are very easy to produce with an FPGA. 

For sawtooth and sine waves, it would probably be a good idea to devote 8 or more FPGA IO pins to a resistor ladder DAC hard wired to an EXP pin on the cartridge edge so firmware can implement non square waves, but even then game support for such sound capability is very limited.

I belive that PWM modulation for non square waves is good enough in terms of nes world. By the way, sawtooth channel in VRC6 is fully digitally generated, probably most of other famicom chips fully digital also. Anyways, 100% of IO pins already used, so i definately will not make resistor dac
Title: Pulse density modulation
Post by: tepples on November 07, 2012, 09:26 PM
The GBA and DS use pulse width modulation, and some people claim to be able to hear intermodulation with the 32 kHz carrier.

But you don't need a resistor ladder DAC to beat PWM. You could use the so-called "1-bit DAC" that SACD and like a lot of CD players use. SACD plays a PDM stream at 2.82 MHz, which isn't much more than the 1.79 MHz on the M2 pin of the NES cart bus. If your mapper's synthesizer produces an 8-bit audio output, you can make a basic 1-bit DAC by feeding this output into an 8-bit adder to generate a PDM stream. Put the adder's carry output on the audio pin, and run that through a cheap low-pass filter to reconstruct the analog signal. See "delta-sigma DAC" and "pulse density modulation" on Wikipedia for more about how this works.

Oh, did Anyone else here know about the upcoming Russian made Famicom flash cart?

Ah so basically the 1 bit output pulses between V+ and GND and the duty cycle (or density rather) controls the charge level of a capacitor to produce a step-less analog wave that can vary in between the digital extremes.  Nice.  So 50% duty cycle results in the capacitor filtering the line to a steady (V-GND)/2, etc.

Anyway, what the hell is the «mapper compatibility» chart supposed to explain ?

The mapper chart and mapper numbers correspond to the original iNES emulator and rom dump format.  All NES rom image files using the .nes file format have a header which has 1 byte for the mapper identifier thus giving 256 possible mappers which the emulators use to handle mapper behavior and flash carts use to select the appropriate FPGA firmware to load.

Numbers assigned to known and/or official commercial mappers are completely arbitrary and assigned by the community as new mappers are discovered, invented (home brew) or reverse engineered and implemented.  "Bad mapper" basically means that number is free and not used or assigned to any known real world mapper (eg: there are less than 256 mappers in reality even including home brew and pirate mappers), or specifically a mapper number that was erroneously assigned and now retired and not to be used.

You'd have to check out the nesdev.com wiki among other places to figure out what physical mapper (eg: MMC3) is assigned to what iNES mapper number.  For example the MMC3 family of mappers are assigned iNES mapper #4.  When a PowerPak or Everdrive loads a .nes file and sees 0x04 for the mapper it knows to load the MMC3 configuration file into the FPGA.

http://wiki.nesdev.com/w/index.php/List_of_mappers

Castlevania III works just fine, though the retrousb / PowerPak site is outdated and you need to update mappers provided by the nesdev community.  You can even mod your NES with a single resister on the expansion port to get extended audio, but you need the Japanese ROM for that for obvious reasons.  Namely the .nes file specifies mapper #24 for VRC6a and most importantly actually implements the program code to manipulate the added audio channels that won't be present on the US program ROM.

Currently there are only like 5 games that don't work on the PowerPak or something like that.

I JUST bought a PowerPak but will pick up a NES Everdrive too just for collecting purposes ;)

It's easy.  The NES moved the audio mix pins to the expansion port and removed them from the cartridge port.  However the NES *also added* additional expansion port pins to the cartridge that also go to the expansion port.  Thus in the expansion port, you have right next to each other the original audio input mix pin AND extra unimplemented pins to the cartridge port that are unused on all commercial NES boards.  But those unused pins *can* be implemented only by a custom cart like a PowerPak or Everdrive to output custom audio.  (or custom wired with a Famicom to NES converter, same principle) You just have to connect the two pins; using an appropriate resistor controls the volume of the extra audio.  47k ohm is about right.

http://www.nintendoage.com/forum/messageview.cfm?catid=22&threadid=32915

The audio mix input pin is fixed in the expansion port at pin 3, but there are also 9 expansion pins between the expansion port and the 72 pin cartridge port that do completely nothing, as no commercial NES cart uses them and most don't even have cartridge contact pads there (the blank middle section you see on NES carts).  But those contacts ARE present in the PowerPak and Everdrive and they are connected to the FPGA to output whatever you want when you write FPGA firmware.  The convention chosen for the PowerPak is using EXP6 which is pin 54 on the cartridge to output extra audio.  This maps to pin 9 at the expansion port.

Thus a 47k ohm resister connecting pins 3 (audio mix input) and 9 (FPGA custom audio output from cartridge) of the expansion port map the PowerPak/Everdrive's custom audio output to the NES's audio in and at an appropriate mix volume.  This is completely safe to do because no commercial NES game ever uses those pins and the EXP port was never used for anything on the NES.  The only thing that will ever "know" about the mod is the PowerPak/Everdrive, it won't conflict with anything else. 

Additionally if you have a Famicom to NES adapter, the EXP pins on the NES side are left unconnected.  IF the "gold finger" contacts are present (even if they are, they won't be connected to anything), you could also use a wire to connect to the audio out on the Famicom side to the same cart pin 54 on the NES side and get extended audio from Famicom carts just the same.

Note however that you will not get extended audio from anything but Japanese or custom ROMs, as NES ROMs will not contain either the physical audio hardware or the programming to make use of it since cartridge audio wasn't officially supported on the NES.

As far as the NES Everdrive implementing audio, it's a Cyclone II FPGA, you can support whatever you want on it, within the limits of the cartridge interface provided to the NES.  There is no difference in hardware between a Famicom and NES flash cart except for how the designated FPGA IO pin for custom audio output is wired to on the cartridge edge on the PCB (famicom's audio out pin or NES expansion pin to be used with modded NES).  There is no custom audio hardware, it's all implemented in the programmable FPGA.  To get audio you just write a complete VRC6 mapper for example and load it into the FPGA, it functions the same on a Famicom or NES (though only a Famicom VRC6 program ROM is actually going to utilize it in software).

I assume Krikkz (or anyone who writes mapper VHDL to be specific) will keep it simple by following the established convention of using EXP pin 9/cartridge pin 54 for extra audio output like the PowerPak otherwise which pin you connect to EXP pin 3 will change for the NES Everdrive.  It would be a monumental task if not impossible for Krikkz just to *implement* every mapper himself, let alone get them all 100% perfect.  Each mapper has so many quirks with regard to things like exact PPU pixel timing for IRQ generation and many other complicated issues.  So likely the mappers are going to be written by the same community members who keep the mappers for the PowerPak up to date who already have individuals with expert knowledge with specific mappers. Some of the reverse engineering of the mappers has been a decade of progress and some are still being perfected.

For Krikkz to do it all would be doing the research, development, and hardware debugging equivalent to creating the Super Everdrive 50+ times over from scratch. It's called mapper hell for a reason :)

Thanks for that awesome explanation, exdeath. That is a pretty simple mod and I think the single hardest thing would be finding a 47k resistor locally. I'll try Radio Shack and if they don't have one I'll just order online.

Looking at the pics of the pcb those look like flash chips not ram.

invitenes is flash based not ram based.
Care to elaborate? The specs below say otherwise.
InviteNES specs:
2 MB of RAM for the PRG
2 MB of RAM for the CHR
Cyclone II FPGA as mapper and logic (SRAM based).
Cortex-M3 controller (co-processor for memory card, SRAM, and FPGA)
32 KB of battery-backed WSRAM

Also the nes powerpak has many shortcomings.  The saving system is terrible, the mappers are mostly incomplete (getting mappers that save with certain games is really hard, also the mappers glitch a lot).  Getting extended audio wired into my av famicom requires modding because the stupid thing is a nes cart.  There's a lot of stuff on the nes powerpak that either glitches or doesn't work because of incomplete mappers.  The default mappers that come with the nes powerpak are way worse than some other mappers I found on the internet and the retrousb website doesn't mention the better mappers that're out there.  The list goes on and on, basically the nes powerpak has been dead for quite some time but up until the famicom everdrive comes out it's still the best thing you can use.  What I'm hoping with the famicom everdrive is a ram based flash cart with the amazing krikzz saving system (way easier to use) and much better mappers.  The nes powerpak also if you tell it to reload the last game you loaded the savedata won't load properly so everytime you have to reselect the save file manually for it to load which is annoying.  I'm also loving how there's a famicom version which is more compact and won't need any special wiring or adapter to get awesome music.  There's a reason why all of my personal systems are famicoms, famicoms are just better systems and all the best modding circuits I found are designed for the av famicom.

By the way, i discover that original famicom and famicom AV have pretty different sound levels, VRC volume on AV famicom much higher than in original fmicom, so VRC6 channels stifle internal audio channels.

Pin 45 on the famicom slot inputs the system audio into the cartridge.  Pin 46 outputs the system audio mixed with cartridge audio.  If the cartridge doesn't have any upgraded audio then the cartridge pcb has pins 45 and 46 bridged so the system output makes it to the audio output jack.  Pin 45 is the system audio output only without cartridge audio mixed.  Pin 45 doesn't connect to any av jacks.  Without anything connecting pin 45 to 46 you won't hear anything.  Pin 46 is the output of the system audio mixed with the audio from your cartridge / flash cartridge.  The system audio is therefore inputted into the cartridge at pin 45 and the mixed audio is outputted from pin 46 to the av jack(s).

Maybe if you use a spring loaded Micro SD slot, you could have it sit flush against the case. But, since the entire Famicon/NES game collection is ~236MB, all games could just be installed onto one Micro SD card and left inside the case. Developer wise, having access to the card could be useful...then again, developers would more than likely go with a USB version (assuming that is an option)...yeah, I'm rambling.

I prefer a premade card slot. Not everyone has the time and tools to properly cut into a cartridge. It seems silly to have to open up a cart every time you want to add games to it.

 Perhaps the microSD slot can be on the top of the cart, like the PowerPak?

Really, the list of games itself would be smaller since most people won't be adding games like Sesame Street, Barbie, or most sports games (with the exception of Tecmo Bowl, in my case). The only decent reason to have the SD slot easily accessible is to do an OS update for the EverDrive itself.

And it's not that hard to cut a small hole for a slot in a case. I've done it using just a Leatherman's multi-tool for my Super ED.

It saddens me that so many people think that only the old commercial games are worth playing... What about hacks? Homebrews? A lot of cool NES games have been made recently, and I really expect/hope there'll be more. Not only for the NES, but for many other consoles too. I don't want to have to open the case every time someone releases a cool homebrew game, so internal card slots don't make much sense to me...

EDIT: BTW, making holes in cases is not hard at all. You know what I used to make my Mega Everdrive case? Nail files. You just need a little patience. The hole for the pause button did require a small drill though.

if the falicom verison comes out sooner i know a CHEAP way to get a region converter if one wasn't afraid to do it themselves, i mean from a place that u buy bare chipboards y not lol just get Gyromite  off ebay and use it's cart to make a us nes cart and it has teh converter in it already btw game can be aquired for 5-10 bucks lol

The only problem with putting the guts of a converter and Famicom Everdrive in an NES cart is accessing the microSD slot. Unless the microSD slot on the Famicom everdrive was on the side, then you could cut into the NES cart...

Post by: stonie on December 06, 2012, 02:35 AM
ya but if i did it like that it wouldn't be a big deal i like having the chip in the cart, and since the falicom pcb would be smaller width then nes cart i assume it would fit like that no matter where the slot was
Title: Re: Mysterious cat detected!
Post by: RGB_Gamer on December 06, 2012, 04:29 AM
Of course, you could always just use a Famicom to NES converter, but that would be too cliche I guess. I don't really have that issue, since I have an HES Unidapter

Out of curiosity as someone with a NES rather than a Famicom, is there any chance you'll decide in advance which cartridge pins will be used for the addon sound mixing?
Us regular folks would probably like to be able to mod our consoles in preparation, well before release.
There's also a couple of projects that would be affected by which pins get used, such as the "NES Super 8" motherboard redesign. (http://www.atariage.com/forums/topic/203257-nes-super-8-project/)

This might be the first Everdrive where I actually buy the plastic shell along with the board. I can't figure out how to open most Famicom game carts since they're snapped together with no easy way to open them instead of screwed together like normal, sane game carts. I think Neo Geo carts are the same... no way to open them.

The biggest problem is that famicom shells does not have standard layout, i open up around 10-15 carts, and almost all of them have different layouts inside. Everdrive PCB will fit in some of them, but not in all. So i have plans to take care about shells supply

Except you'd still be stuck with a salamander label or no label.  I don't need to see my everdrive I like having a case where I can't see the pcb as long as I have the awesome labels by arcade (which I do).

It needs to be pushed DOWN to work. I have seen Famicom to NES adapters that don't need to be pushed down like my friends' unit. But MINE does (and it's the exact same style). Go figure.

I was not really talking about space, but about the difficulty of accessing the memory card. =)

If it's supposed to stay inserted 100% of the time without easy access from outside the case, adding stuff to it will be very inconvenient. The same goes for people wanting to use this for development purposes, who need to load new ROMs very frequently.

I'm not much of a pirate, I don't enjoy having complete ROM sets in my flash carts with tons of crappy games and useless European versions just making it harder for me to locate the ones I do like. But when I discover an interesting game I like to be able to easily put it in the cart. This why this whole notion of "just put the entire library in the card and forget about it" is so weird to me.

Then get the USB version if there's one available. I don't see what the big deal is about having to take the micro SD card out and back in when its easily accessible. I do it every time with my NDS flash cards as well as my other EDs. I'm sure KRIKzz made the design with ease of SD/MicroSD card removal in mind.

Seriously, kids. It's not a big deal. If it is, then get the USB version and call it a day.

I know it's probably way too early to ask this, but will there be any way to play the .vs PlayChoice-10 arcade games with this ROM cart?  I've been following a forum where people were able to get vs. Mario Bros working on the PowerPak by mapping the coin button to select.  Also, I believe they got vs. Duck Hunt working using a similar method (requiring that both the gun and controller are plugged in at the same time to different controller ports...obviously).

I would really love to see those games playable on the NES Everdrive!

I'm sorry if it's already been covered, KRIKzz, but will this new ED be able to play .FDS (Famicom Disk System) based games? Granted, most of the games released on disk were converted to cartridge for the NES.

Also, how are firmware updates handled? JTAG or can it be updated from SD?
Title: Re: Mysterious cat detected!

can you update firmware with everdrive carts without jtag if you have a usb port installed? if so i may go with a usb port version if it's going to be available.

The USB is used for development. Makes it easier for homebrew game/app programmers to load their ROM to the ED without the need to remove the SD card every time to reload the ROM.

User just should copy new OS and mappers files on sd card, they loads at each startup. JTAG or any other equipment is not need.

Good to know about updating. Been contemplating getting a JTAG programmer for my other EDs, but I'll just have someone update the FW for me. Thanks.

Looks like the new ED will function similar to the ED64, as the OS will be on the SD card along with the mappers. Very nice.

Excellent.  You do a great job updating your firmware.  It's amusing that bunnyboy is making a new powerpak because you're stealing his business.  A famicom flashcart is way better than a nes one, and yours is ram based, plus you've shown that you actually care about updating your firmware and fixing bugs.  You also have this forum where you respond to people pointing out problems and you get it fixed, I messaged bunnyboy about bugs with the powerpaks and nothing got changed.  The powerpak has had the same buggy mappers for ages.

May be someone know something about fds sound except like this (http://wiki.nesdev.com/w/index.php/FDS_audio) information? Mod calculations looks pretty weird, hard to belive that such kind of calculation was implemented in real chip.

If you do go this route (I am), you'll have to disable your NES' 10NES chip by cutting pin 4.

I had my NES sent out to be RGB, stereo and region-free modded a few months ago.  I haven't tested the region-free yet, but the RGB and stereo work GREAT, so I can only assume the guy did the region-free mod correct as well.

BTW, the RGB output looks AMAZING.

As far as i know nes cic is similar with snes cic, NES has different keys and more keys (4 instead of 2 on the SNES). And some other minor changes. Well, we will see if i have enough information to make my own CIC

From what I understand:

Tengen was the only company to release unlicensed NES games with a working, self reproduced CIC chip (other companies used methods, such as hitting the NES CIC with a -5VDC spike that would knock out the chip. This was later circumvented by Nintendo in later NES revisions).

Long story short, Tengen attempted to reverse engineer the original NES CIC, but failed. Instead, Tengen obtained the algorithm from Nintendo's existing patents at the US patent office (by lying and saying that they were in a infringement lawsuit with Nintendo). After obtaining the algorithm, they manufactured their own chips, known as the "Rabbit".

The algorithm has been rediscovered by extracting it from Tengen's Rabbit chip, as it was less secure than the original NES CIC.
Something about a debug mode.

thefox on nesdev.com hosted this a while back.
http://thefox.aspekt.fi/Tengen.c
Apparently it's Tengen's Rabbit CIC's algorithm translated to C (from what I gather, it's based on the Tengen instruction set and the extracted code, via the "debug" mode the Rabbit chip had). He admitted it may be faulty, since he wrote his own disassembler, but it seems to be the most important info I can manage to find (since everything has been deleted  :().

I think the PIC12F629 is used for the CIClone, but I could be incorrect on that.

If the "region-free mod" you had done is just the cutting of pin 4 on the 10NES chip, it should work fine. I can't imagine that anyone would do a "region-free mod" on a NES in any other fashion. It's just too easy... uses zero components and causes no undesired effects (with the rare exception of carts that depend on the CIC/Reset signal).

Cool! I wish you the best of luck with your own CIC replication.
Is there anything else that would be very different from your Famicom board? It seems like just the addition of CIC + a PCB redesign = working NES Everdrive. Unless I am missing something. Differences with the sound channels should be pretty basic to sort out, I would imagine.

If so rather than different boards/PCB wouldn't invest in making those adapters be a better choice? You make the board once and then people that need an adapter would buy it as an add on ;-)

 also i know nothing about it but after the problems mentioned with the nes cic, is there going to be an issue with game incompatability due to the cic? i know there will be some incompatability until the mappers are implemented but i didn't know anything about the cic thing.

more optimised meand that pcb layout will be designed for nes shell, for example you will not be able to acces to sd outside of shell if you will use fami+adapter.

Krikzz, thanks for making the menu option for audio modes. Finally AV Famicom users will be able to hear the games the way they were meant to play heard. Don't worry about Twin Famicom or other mobo revisions because they're close enough to the original Famicom.

Your assumption is correct that the NES will refuse to boot the Famicom Everdrive with a stock CIC. However, the CIC on the NES is amazingly easy to disable, especially in comparison to other consoles. You lift a single pin and you're done.

I like pretty pixels and scanlines. S-vid can be on par with RGB, it's circumstantial. I don't think Drakon is arguing that S-vid is superior, just that S-vid can be indistinguishable from RGB in certain applications. I do love keeping signals separated and pure as much as possible, but at the end of the day, if it looks just as good and is an easier solution, I'm all for it.

I'm pretty sure that the only game that will refuse to run without a functioning CIC is NWC.

Jeez! Drakon, will you please lay off posting a bunch of pictures anytime someone mentions RGB or S-video? You do it on all forums.
This does indeed seem to be a repeated issue. May I offer a suggestion Drakon? I advise resizing your photos with a program like AhaView. Some people browse on cellphones on plans that bill for bytes of information, so if you really wanted to be considerate of these other forum members, you could place your pictures in spoilers. I see you have -30 rating under smite, so I do believe this "picture issue" has to be involved in some way.

if nintendo world championships is the only game that wont run then disabling the cic seems like a no lose plan. aint NWC just that competition game with 1 level from 3 games on it? i'm sure i seen it on a angry video game nerd episode. can anyone confirm if NWC is the only game which refuses to boot without the cic?

You definitely use many more components than any other ED, I guess separating CHR and PRG mem makes the whole project easier to work with, but it is a lot of chips in there.

Regarding Audio I just hope that it sounds right and not distorted, luckily you can change the sound functionality in the FPGA later if needed. It is nice though to have 2 audio levels to play with from the start.

What is the compatibility so far? It would be nice to have a graphic spreadsheet (like PowerPak) of mappers that work, not work, work in progress etc... but you're busy so it can wait until you launch the product.

BTW I noriced you used a 1.2V voltage regulator, for my own education what part of the circuit uses 1.2V in a famicom?

I just realized how stupid I am.
Of course Famicom to NES adapters are going to have a CIC installed into them... shouldn't need to disable your CIC at all.

I'm still waiting on mine in the mail, otherwise I'm sure I would have figured this out sooner. I'll post some finer details on the adapter if I find anything out of the ordinary once I get it.

Here's a list of NES games that have the potential of containing an adapter:
http://famicomworld.com/workshop/articles/nes-cart-converters/

Apparently, the only sure way of determining an "adapter cart" (without opening it) is by looking at the pins on the cart. Notice how the tips are offset on the adapters. It's been reported that not all "5 screw" carts have adapters.

What's the battery used for?
It allows to not reset the system every time when you want to save game before than shut down console. Saves "lives" in sram and os copy them on sd when you change the game

That's a great idea!
Title: Re: Mysterious cat detected!
Post by: butfluffy on January 31, 2013, 02:01 AM
thats quite a list of games which potentially have an adaptor. trouble is verifying if the cart may be an adaptor version while trying to purchase online. my paypal went tits up so ebay is out the question for me at the moment.

I don't have a NES/Famicom, but I've been reading all this as it's very interesting, and I think it's great that owners of these consoles are getting an Everdrive.

I do have one (possibly stupid) question, though; why are some circuit boards green, some are blue, some are red, etc? Does the colour indicate anything important, such as the brand, or the power level needed to power the board, or the (I don't know  ???) width of the metal lines that conduct the electricity? Or is it just down to the random colour that the board manufacturer chooses to use?

flash bios
cpld for usb/sd interface and fpga firmware loading
cyclone2 fpga
voltage shift buffers
that's all

krikzz what are the final board specs, specifically, chip sizes?

Haha thanks I missed that.  This's one extremely well designed flash cart.  The biggest reason why I'm excited about this is krikzz is amazing at keeping his firmware up to date and fixing bugs / issues quickly.

Hey, that's neat. Options are always good.

I don't have a huge desire to plug Famicom games into my NES, personally. A nice sealed NES cart with Famicom Everdrive works better for me. I'm going to opt to spend my time modding something that hasn't already been mass produced by Nintendo.

Also, down the road, I may just sell off my adapter, buy an NES Everdrive and then I'll have one more reason to go buy an actual Famicom.

You will lost options settings, and last save (if it was not copied to sd)

BTW I noriced you used a 1.2V voltage regulator, for my own education what part of the circuit uses 1.2V in a famicom?

Famicom uses 5v only, 1.2v from fpga core, 3.3v for fpga IO and other chips.


krikzz what are the final board specs, specifically, chip sizes?
Cyclone2 FPGA. At this time, biggest mapper (FDS) used less than 30% of chip resources
Static RAM for PRG and CHR
PRG 512K,
CHR 512K,
128K of battery backed ram, can be used as extra PRG rom, or as save memory
Voltage shift buffers on CPU/PPU bus for reduce noice and power consuption
1Mbyte flash bios
usb for developers (as usually)
MAX2 CPLD (BIOS,SD,USB handling)
Loading time for the biggest game around 8sec

the battery looks like a standard lithium battery that just clips in and out with no soldering/desoldering needed, unlike with my old copiers. this is a nice touch when it comes to replacing the battery. some people saying it's a bitch to open nes carts, i've never tried to open one, how hard can it be? i guess it's not a big deal to open the nes shell a few years at a time to replace the battery. i was in two minds last night about getting the famicom version and tracking down an adaptor but now i've slept on it i will be waiting for the nes version. it will be way better to be able to remove/insert sd cards without having to open the shell everytime. just hope the nes version won't take a really long time i guess.

Which option settings will be lost if the battery dies?  Also do you plan to implement stuff like konami vrc6 and vrc7?  I'm wondering if the vrc7 would take more resources than fds stuff.

It's great that you're working to remove noise / power consumption.  That's one thing I've noticed about my mega everdrive and turbo everdrive they don't add any noise or distortion at all.  On my rgb modified nes / famicom systems using the nes powerpak makes weak video jailbars appear (you don't get jailbars with regular carts).  My first snes with the translucent bar in the middle of the screen when I used the snes powerpak the bar went from being clear translucent to a green translucent colour making it even more annoying.  Luckily I've managed to fix the translucent bar in the snes but obviously noise and power use can be an issue with flash carts.  All krikzz flashcarts I've used have been free of adding interference, they're nothing but the best.

One question about compability...

I've been trying to run NTSC games that give problems playing on a NES PAL changing timings of CPU and PPU but I have not gotten anything. For example Zelda II NTSC gives glitches on a PAL NES.

There would be any chance to operating correctly NTSC games on a PAL NES??

super wild card for the snes and super magic drive plus for the megadrive/genesis. i have some doctor v64's lying around aswell for n64 but they don't have built in battery because you still needed a passcart for n64 roms to load. the ds1 saver for the n64 copiers sram saves has a battery though. batteries are a pain lol.

NES carts are incredibly simple to open, but you need a 3.8mm gamebit driver.
Famicom carts are difficult. They have plastic snaps, as opposed to screws.

cart option: audio mix level, file sorting, reset to game, sram backup. Without battery, all this options will be reset to default. Also cart will forget which game was selected last times
VRC6 already implemented with sound, VRC7 probably will be implemented at later.  VRC7 will use more FPGA resources than FDS. Right after final testing i will start working over Namco 106 sound

Wow that's awesome.  Someone told me that the vrc7 is pretty much the same as the fm chip in master system so that'll hopefully also help with recreating the master system fm in the mega everdrive.  Too bad the only vrc7 game that uses the audio isn't fanslated.  It's a huge pain to hack the lagrange point rom the entire rom is compressed.

i think mmc5 is playable on the powerpak but only when using unofficial mappers. i'm not certain of this, it was a while back when i was reading up on this stuff. someone was saying they played castlevania 3 from start to finish but some other games were still buggy. of course it may have been something other than mmc5 i'm remembering but mmc5 seems to have stayed in my memory.
Title: Re: Mysterious cat detected!
Post by: tokumaru on February 03, 2013, 02:10 AM
Yes, there's an MMC5 implementation for the PowerPak, but it's incomplete (as opposed to buggy). The MMC5 is a pretty complex mapper, with extra sound channels, a number multiplier, several graphical enhancements (simultaneous access to more tiles and better color resolution for the background), among other things. Castlevania 3 barely uses any of these features, so it runs fine.
Title: Re: Mysterious cat detected!
Post by: butfluffy on February 03, 2013, 12:04 PM
i would be happy with an early version of mmc5 if only for castlevania 3 to work properly. maybe it can be improved on in the future. or maybe some would prefer no mmc5 support unless it's perfected. i gather it's a big job either way. if anyone can.... krikzz can ;)

Just because you didn't have problems doesn't mean others didn't.  Not sure why you feel the need to continue arguing on this topic.

You even proved my point with your reply.  You stated you bought it 'as soon as it came out'.  Both of those carts sold out fairly quickly after release.  You were lucky enough to get in when the first batch were posted for sale.  If you had come later, you would have had to wait for the next batch.  That's why myself and many others have been watching the site for stock of the SD2SNES and Everdrive N8.
