I haven't really been studying the SNES as much as the NES — all I can point you at is http://wiki.superfamicom.org/snes/show/Ports+%26+Pinouts but I can't find any 5V 4MBx8 EEPROMs on digikey. SST sells some 512kx8 EEPROMs (SST39SF040) and you could stack 5 of them (augh) and Atmel sells (sold?) a...

I can look at the pinouts and figure it out, probably, but it would help if someone had some more detailed information.

Yeah, I guess that was a silly question. What I meant to ask was, are they available with an EEPROM already on them? I don't have any surface-mount equipment with which to attach one, so if they're not I'd have to find someone who could do it for me. If I did, what EEPROMs would be appropriate, as f...

SFC cartridges and low-profile EEPROM

Just wondering: I've seen pictures of Super Famicom cartridges that have had the mask ROMs removed and replaced with a sort of converter board that allows a surface-mount EEPROM (TSOP package, I think?) to be plugged into a DIP socket. I have a couple SFC cartridges that I'd like to convert to use p...

I believe I got error #22, actually, but the paralell port did turn out to be the problem. However, if you're stuck with your laptop as the only computer with a paralell port, try going into the BIOS and setting the paralell port to EPP mode - it didn't work for me when it was suggested, but it migh...

Yobo FC Twin plus SNES DOOM. The NES portion is the same buggy NoaC Yobo's other clones use, but the SNES part works great (although a few carts don't work.)

I had troubles running from a laptop when I built my FDSLoader setup, and I was told that laptop paralell ports are basically complete crap. Try it from a desktop computer and see if that works - it did the trick for me.

You mean like code the PPU in verilog for an FPGA?

There are open source 6502 cores, I believe.
Well, if anybody feels up to it, they could certainly do better than the NOACs in use.

If you don't have soldering equipment and don't have a snipper-type tool small enough, you can do what I did and gradually saw through it with a razor blade.

Hmm, I'd thought about the write-redirecting thing for an idea I had (an updated FDS-type thing using standard 3.5" floppies,) just to give it more RAM while keeping the BIOS in the same place. Interesting.

Well, as long as you're not selling it, it would fall under fair use and you shouldn't get in trouble even if the BBC did care.

Odds are there's an NSF dump of the game that includes the sound effects. You could just use that.
