Need Help Dumping Nintendo Campus Challenge Reproduction
I have a 1992 SNES Campus Challenge Reproduction cartridge and i am trying to dump it but its not showing up. I am using a retrode 2. Can someone please let me know how i can make this happen, whether i need new hardware, or a new process?
First you'd have to find out how the campus challenge "talks" to the snes (banking hardware/registers etc)
Then you'd have to find out how the scripts of the retrode work...i'm sure there's an example on their site or whatever.
If you have those two you'd have a pretty good way of dumping it.
I won't get into the minefield of the ethics of dumping such a cart.

Can do.byuu wrote:Send it to Guru and have the ROMs themselves read out directly. Then if needed, send the image to d4s to crack any stupid protection checks.
Note: either of them may be busy or not want to do this and say no.
I haven't delved too deeply into the hardware.
Shouldn't be too complicated, though.
IIRC, the original pcb had a microcontroller interfaced to the SNES via a dual-port RAM and there was some sort of rudimentary network port present aswell. (couple of pictures)
The above is a dump of the retrousb cartridge.
I'm not sure if and to what extent the ROMs were patched in comparison to the original cartridge.
I was also given a partial dump of the original Powerfest 94 ROMs for evaluation, which ran on similar hardware.
However, I've promised not to share that one.
The Retrode appears as just a standard FAT formatted disk to the computer, so the C code you would have to write is the AVR firmware. All the A bus pins are connected so you could read/write anywhere.byuu wrote:If there were a way to dump the full 16MB address range with the Retrode, we could trivially write C apps to handle any mappers. Is that possible?
Well, if we can get a guaranteed clean dump, I wouldn't mind poking at emulating it. Experience tells me the network communication stuff probably won't happen though.I'm not sure if and to what extent the ROMs were patched in comparison to the original cartridge.
Oh? I thought Matthias said it couldn't write. In that case, dumping the S-DD1, SPC7110, and Cx4 (in MMX2, MMX3 can be dumped directly) should be trivial. And all we need is a proper SuperCIC integration to finally have a 100% compatible cartridge dumper. Awesome stuff!The Retrode appears as just a standard FAT formatted disk to the computer, so the C code you would have to write is the AVR firmware.
