Hi all,
I have come across a CPS2 fault that has me completely stumped.
Super Turbo/2X - am getting jailbars through quite a few sprites which are all over the memory space, so it's not an individual mask ROM causing the problem.
- Ryu on main screen
- Lightning effects are missing/garbled on main screen
- Cammy and Chun Li
- Akuma
- Various characters on select screen
- Various parts of the fix layer in game such as life bars and super meter
- Some character sprites and not others in game
Things tried so far:
- All mask ROMs tested, 1 bad one replaced (20)
- 3 different B boards, 2 rev 7 and a rev 3
- All unique PALs replaced (B, G1 and G2 on daughterboard)
- Removing various mask ROMs to try to locate the fault
- Using MAME and removing combinations of ROMs to replicate the fault
This one has me completely stumped. It's missing data somewhere but I can't find where or how.
