How is progress going on the driver at this point? Since it's been almost two months since your last post I figured I'd just ask out of curiosity. Have you been able to squash the last remaining bugs in the MK games?
Obviously I can't say for sure, but you need to consider that, in addition to the TMS34010 CPU core, there is also the ADSP2105 core (the microprocessor for the audio sub-system), so, probably, there's still much work to be done... we need to be patient and to thank Romhack for the work he's doing!
PS: apart from the MK games, there are many other interesting titles related to the TMS34010 CPU, like the little known Art & Magic's games (Cheese Chase, Stone Ball and Ultimate Tennis).
