Taito JC System Taito JC System
Driver by Ville Linde, based on the preliminary driver by David Haywood 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.
