If you look at the Unisystem VS schematic, you will see that the roms are mapped in memory like this:
- 1D: $8000 to $9FFF
- 1C: $A000 to $BFFF
- 1B: $C000 to $DFFF
- 1A: $E000 to $FFFF
# cat mds-sm4.1d > mds-sm4.bin # cat mds-sm4.1c >> mds-sm4.bin # cat mds-sm4.1b >> mds-sm4.bin # cat mds-sm4.1a >> mds-sm4.bin
The same concept applies to the PPU roms: 2B comes first, then 2A.
NOTE: Dont bother asking me for the ROMS or where to get them, I wont reply.
