MAMEWorld Forums - Programming - Checkman PCB Mame Roms Help

Hey everyone

Need someone thats either cluey with reading z80 code or who may own a Checkman PCB

Basicly i own one but sadly the program roms were corrupt, i tried to use the sets in mame and couldnt get it to work but after a bit of mucking about i compiled all the roms into a single rom and got the game to boot but only after you coin up the game other wise it just sits on garbage other then that game starts and plays fine but sadly i cant get the sound pcb to work yet

this pcb is not the original checkman pcb i am using but a fully working galaxian bootleg pcb i used, the original pcb is just a bootleg galaxian pcb so i really dont understand why its doing this there are no mods cut tracks/wire links anywhere on the original pcb

Both pcbs match as in memory map ect but i think the roms i require are for it to work correctly are not dumped or been modified to run

Is anyone here smart with reading and understanding code that could help me out with this?

Cheers
