- dendego intro object RAM usage has various gfx bugs (check video file)
- dendego title screen builds up and it shouldn't
- dendego attract mode train doesn't ride, the doors light doesn't turn on.
- dendego/dendego2 train board (external sound board with OKI6295) is not emulated. where is it accessed???
- dendego2 shows a debug string during gameplay? it also shows up in the 2nd demo run.
- landgear has some weird crashes (after playing one round, after a couple of loops in attract mode) (needs testing -AS)
- landgear has huge 3d problems on gameplay (CPU comms?)
