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.

Never mind, it is in fact another faulty B board. Track rot around one of the customs. That sucks but it might be fixable at least

It's not mine to sell I'm sorry :)

Doesn't look too bad so I'll probably fix it at a later date

xodaraP,

I had a similar issue on a CPS2 with vertical bars and wrong effects. Ended up being only some oxidation on some pins of the connectors between boards. Just had to clean them. Also in can happen with bend pins

I've already checked those but thank you, one of the customs actually has corroded pins I believe are causing the issue.

I think it is probably fixable but I will have to look at it another time
