Ive got an LSI Marble Madness cart that I am trying to get working. I burned new ROMS and just double verified them. I used the "marble5 Marble Madness (set 5 - LSI Cartridge)" set from Mame. I think one of the PROMs may be the issue but have no way to test it. The game plays and sounds do work but the test menu doesn't come up either. I know the SLAG chips are fine since they work on another board.
Any ideas?
