Taito JC System
Taito JC System
Driver by Ville Linde, based on the preliminary driver by David Haywood
Taito custom chips on this hardware:
- TC0640FIO : I/O
- TC0770CMU : Math co-processor?
- TC0780FPA x 2 : Polygon renderer?
- TC0840GLU : 2D graphics?
- TC0870HVP : Vector processor?
TODO:
- 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.
- 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?)
- dangcurv DSP program crashes very soon due to undumped rom, so no 3d is currently shown.
- add idle skips if possible
- POST has a PCB ID (shown at top of screen) that can't be faked without a proper reference.
