ROM-Reader for Super Nintendo / Super Famicom Game Cartridges

I've been trying to adapt 27c801 eproms to work with the cartreader, no success tho.
Could you try to make it program 27c801 eproms? I'm a newbie in arduino and in writing code.

JCreazy:
which makes me think it is being dumped somewhat correctly

You could use a Hex Editor like HxD, open both the dumped and the known good rom and compare them to see where they differ. CTRL+K and then F6 to move to the next difference.

I use my TL866 to program 27C801 eproms. It's a very cheap Chinese programmer that can do a lot of stuff.

Just recieved my repro of conker's bad fur day, i tried to make a backup of the game and my current save file, it backups both successfully but when i try to write the save back to the cartridge it looks like nothing happened, it writes and verifies successfully but when i put it in the console it still has my last save file.

Edit: Tried reflashing my cartridge, and all i get is a black screen. Tried changing the file in an hex editor, tried using patches and still nothing the only game that worked was banjo tooie. I have a PAL N64.

Perfect Dark and Donkey Kong 64 should also work since they also have 16K eeprom and 6105 CIC just like Conker and Banjo Tooie.

Is there any way to play smaller games like Super Mario 64?

I finally got around to comparing the Hex of my Golden Nugget dump and a confirmed one. The one big difference I see is there is a large section that is all zeros in the confirmed dump. There is just no data there and in my dump there is all sorts of data. I am not sure what would cause this but it's making me question weather or not the confirmed dump CRC is correct. Without having access to another cart, I can't really say for sure but it is odd how there is a giant blank area in the file.

The known dump of Golden Nugget 64 with CRC32 641885DF is marked as Unverified by No-Intro.

It could be a bad dump.

What is the CRC32 for your dump?

It's 70594d3c

The random data could also be the result of an open bus since I don't have the internal pull-up resistors enabled in the N64 code.

You can try changing the void adIn_N64() function in n64.ino like so:

// Switch Cartridge address/data pins to read
void adIn_N64() {
  //A0-A7
  DDRF = 0x00;
  // Enable Internal Pull-up
  PORTF = 0xFF;
  //A8-A15
  DDRK = 0x00;
  // Enable Internal Pull-up
  PORTK = 0xFF;
}

  //A8-A15
  DDRK = 0x00;
  // Enable Internal Pull-up
  PORTK = 0xFF;
}

I get an identical dump after doing that. Same crc and everything.

I ordered a copy of Golden Nugget 64 and I'll redump it.

JCreazy:
It's 70594d3c

CRC32 Confirmed.

The original known dump is bad.

I'll submit the redump details to No-Intro.

skaman:

So I'm not crazy. Does that mean that the majority of Golden Nugget 64 ROMs that people have been downloading for the past 20 years are bad dumps?

Yes, appears so. Anyone that previously downloaded a ROM received the bad dump.

No-Intro had it marked as Not Verified but that doesn't stop anyone from downloading. The entry has been corrected in the No-Intro database and a copy of the clean dump will eventually replace the old dump.

I just want to say thanks again for making this project and for sharing the source. I was able to refine my design and make this ultra tiny portable version:

I've still got quite a bit of tweaking to do to make it feature compatible (i.e. make the extra shields for SNES, N64, etc) but I'm super please so far.

Nice work. :smiley:
Btw. I love your youtube channel, so many great videos and projects. 8)

Hey sanni, how did you flash super mario 64 on a conker's bad fur day cartridge in this video of yours.
I can only flash 6105 CIC games on my conker repro.

I built a Famicom Cart Reader. The form factor is originally based on sanni's MD-only shield but then I decided to add the display, LED, and button. The reader uses a sketch that is a blend of code used in my various dumpers with the base read functions from postal2201's CoolArduino_v1.0b.ino sketch. The reader also works with NES carts using a standard NES-to-FC adapter.



Nice 8)

Hi All,

I'm currently waiting on all the parts for Sanni's cart reader, but this will be stretching my abilities a bit. I just got the PICkit 3 in the mail and realized I'm not sure I know how to use it to flash the PIC12F629. I assume i can use a breadboard and the SOIC8 along with some other components to flash it, but I'm not sure.

Can anyone point me to some instructions on how to properly set this up?

Thanks,
