Does anyone have anything covering programming the SNES mouse?

btw, IDA will not support SNES at all since it has no support for 65816 CPU (so someone would have to write 65816 disassembly core before it can do SNES)

If it hasn't already been done, I would like to request Konami Track And Field (the first one)
I searched but couldn't find it.

Just remember that Nintendo 64 emulation right now is pretty much one giant hack. When its properly emulated (emulating all the various CPUs and other hardware), the system requirements will probably go up vs what it is right now for the current "HLE" emulators.

try making thebyte into an unsigned long and using this ASM

Code: Select all

__asm {
   push eax
   mov eax, offset starthex
   mov eax, [eax]
   mov thebyte, eax
   pop eax
}
Basically your code fragment only reads one byte of data when you want to read 4 bytes of data (i.e. one unsigned long worth)

So basically the intent is to produce 1:1 images of sealed FDS disks (including any incorrect CRCs or "garbage"/unused data that may be present), the results of which could be entered into a goodnes style database as [!] "100% correct dumps"?

It is not possible, Z80 and 6502 are totally different. It would basically be like writing the game from scratch for the NES.

Looking at a MAME romset for a Playchoice 10 game, there is a file called security.prm which is labeled as being the RP5H01 data. Exactly what the data contains and is used for is unclear.

Does anyone know if the CIC chip (or any similar chip) was used for any known Nintendo arcade machine (dedicated, Playchoice 10, VS Unisystem, Nintendo Super System or otherwise)

Just wanted to congratulate all the gurus here who figured out the NES lockout chip. Anyone know what protection the Playchoice-10 carts used? (I know they used something to prevent operators from copying NES games to PC10 carts) Also, did the VS Unisystem have anything other than the custom palettes?
