It would be handy if someone (i.e. you) can tell whether the current S10 dumps are good or not. I heard there was additional info in the ROMs (an unsupported mode) that can't be read out with any current EPROM readers (iirc smf complained like an old woman about the current dumps). I have at least 6 more of these PCBs that are not dumped yet but I'm waiting for emulation to begin to know whether the dumps are good or not. No point dumping more (bad dumps) until I know they are ok. However at the very least Mr Driller 2 should be good because the ROM types are a completely different type not NAND-based like all the other S10 games.
