TODO:
- dendeg intro object RAM usage has various gfx bugs (check video file)
- dendeg title screen builds up and it shouldn't
- dendeg doesn't show credit display
- dendeg/dendeg2 doesn't show the odometer;
- 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?)
- All dendeg games have random wrong textures/palettes. (can't see any ... -AS)
