Anyone know what kind of prom chips are used as the Graphics ROMs in GT99/2k boards? I have a bad GROM0-0 and GROM0-1 and want to dump them and confirm against mame/romident that they're bad before I continue playing with the board.
Dumped the GROMs, they match fine to romident. Something's wrong with the board that's causing the autotest to think the GROMs are bad, when they're not.
