These roms are for a early SEGA game called Commando. The roms are named by the stickers ontop of them. It is powered by 1 Z80 and 1 Z80A, and 2 AY-3-8910 sound chips. I have taken them off my own boardset, which actually appears to be a conversion as the PC board has the FALCON logo on it, not SEGA. ( Maybe a conversion on Falcon's Donkey Kong ??)
