I really want to play some games which I cannot find on the internet. It looks like you can take the two-byte (big-endian) value at offset 6 and add $61C0 to get the offset where the ROM starts, but there's no clear indication of ROM size, mirroring, or mapper. On top of that, some of these ROMs have been hacked specifically for the emulator. Is it possible to convert those.bin files to a working.NES files? Yes, but it's not easy, and it's not possible to do it automatically (with a converter program).
The.bin file doesn't say how big the PRG or CHR ROMs are.
I had to look at the data myself to try to figure out how big each part is supposed to be. #Super Games Vcd 300 Download serial number.
