QuoteDid preliminary fooling around with the network system tonight... looking inside the main unit, it has 16KB CHR-RAM, 16KB WRAM, 3(!) custom chips, no standard mapper chips. The modem is completely modular too. I have managed to figure out a bit how the hardware registers work and I think I even managed a complete dump of card. It appears to be 128KB. It will not run in any emulator yet of course. Anyways so far I've figured out registers for: PRG bank selection, PRG bank mode, WRAM bank selection, both WRAM enables, and mirroring. I've haven't quite figured out VRAM banking yet, but I think I'm on track. Once that's figured out along with what I've got so far, it wouldn't be too hard to add basic support to an emulator to get it running at least. Figuring out the modem stuff is probably out of my league though.
