I have this Mortal Kombat II pcb, 3.1 revision with 8mbit mask rom chips (no extra rom board) which is giving me all kinds of troubles:
First of all, I can't get the game to boot at the first try, sometimes it gives me a ram error, sometimes a few of the mask check as bad, after a few tries turning the power switch on and off the game boots, the test menu shows all chips as good and the game starts just fine, but the sound plays in "Chip & Dale" mode, it sounds like when you overclock the sound cpu in mame, the music plays faster and the voice samples..well... take a look:
