I really don't understand at all how does this CPLD works. I was thinking it was a variant of a PIC like Memblers used on his Squeedo card, but look like it's not. I think you can freely design the logic that's inside, you should design youreself tons of NAND connexions, right ? Do you setup that t...

So you just have to implement the good mapper on the card (by the way, is the think you call "PRG-RAM" the SRAM usually mapped at $6000-$7000 ?) and to burn your PRG/CHR and here you are, you can test it. Yep, that is what I meant. RAM that is in the PRG bus. That is the area for it norma...

[I think tepples misunderstood the fact that you are not running the Game Genie from your flash cart, but are running your flash cart through a Game Genie. Is that the misunderstanding? The pics show you plugging your flash cart into a game genie which is then plugged into a NES. Oh, right. It does...

-10 almost certainly means 100 ns, not 10 ns. 10 ns SRAM is still fairly expensive today, let alone 15 years ago. Dunno why you're getting glitchy blocks though. Yep, that's what I thought too.. The glitchy blocks are always in the same places, i'll try to figure it out. Hmm... letterboxed... oh, y...

They're currently a lot of different flash card project, and I don't understand that at all. I've heard that was impossible to do because of how NES mappers works and how different they are, and now, I see many different projects. Nothing is impossible ;) .. This project here is for playing commerc...

Yes, and the new board will have holes for narrower SRAM chips aswell.

Some update on my project... FunkyFlashCart that includes: Xilinx XC95144 CPLD chip 512 KB PRG FLASH 32 KB PRG RAM (Battery backed with DS1210) 512 KB CHR FLASH 32 KB CHR RAM -ROMs and the mapper can be flashed with a simple parallel port JTAG cable. -Can mimic many mappers, MMC3 & downwards. --...

What is that huge thing? A cap, a battery? Also, what is that little socket for? A lockout chip? It looks like there is plenty of room for lockout chip holes, especially if you increase the size of the PCB. That way people could solder in their own lockout chip if they wanted. I'd say, start sellin...

Some progress...

I just got it to run super mario bros 3....
The code works fine but the graphics are garbled... there is some odd problem with the CHR side..

How big is the PCB? You couldn't find enough space for solder holes on a full sized NES cart PCB? In my opinion, it is only complete if it runs in an un-modded NES The PCB is around 80x100mm and it's quite full packed already. There are so many NES consoles in the world that people could always get...

What kind of lockout defeat? Or will it require me to open my frontloader and cut pin 4? Will it be available in both 60 and 72 pin versions for those who own a Famicom or Dendy system? No lockout defeat at all.. so it will require you to cut the pin 4 .. or get a lockout chip from some useless gam...
