1212- TC0870HVP      : Vertex processor?
1313
1414TODO:
15- games are running too slow compared to pcb recordings, easily noticeable on sidebs/sidebs2
15- games are running at wrong speed(unthrottled?) compared to pcb recordings, easily noticeable on sidebs/sidebs2,
16  for example the selection screens are too fast, and the driving is almost twice as slow
1617- dendego intro object RAM usage has various gfx bugs (check video file)
1718- dendego title screen builds up and it shouldn't
18- dendego attract mode train doesn't ride
19- dendego attract mode train doesn't ride, demo mode doesn't set the throttle, but it does set the brake pressure
1920- landgear has some weird crashes (after playing one round, after a couple of loops in attract mode) (needs testing -AS)
2021- landgear has huge 3d problems on gameplay (CPU comms?)
2122- dangcurv DSP program crashes very soon due to undumped rom, so no 3d is currently shown.
