Final Fight graphical issues

[armorharmer]

Hi guys,

I bought faulty FF and dead King of Dragons (dead battery I guess).

When I plugged FF in, the graphics had a lot of glitches.



I was happyy to be honest! I though I could swap A board with Dai Makai Mura conversion that I have...
BUT I was wrong, when I did the swap, every sprite looked great, except for the text...



Here's Haggar's name:



Does anyone have any idea what it could be? B board? C board? Please help! I have a friend who can fix jamma board, but he nevered had a chance to fix any CPS board.

Thanks!

If replacing the A board improved the situation, definitely the original A board from the Final Fight game has developed a fault.

Try the A board from Final Fight with your Daimakaimura B board and see what happens...

Thank's for the answer!
Yes, A board on Final Fight is definitely faulty. It was same with Dai Makai Mura B board.
But I was wondering what could be wrong with B or C bord in order to display glitched fonts... All characters look grate, only fonts are glitches (and a small Haggar's picture in the left corner)...

Unfortunately CPS-A-01 and CPS-B-xx chips fail way too often. I've seen them fail myself. And it's usually graphic issues what they cause.

Have you tried to check the graphics ROMs? If you check the graphics ROMs and they are working properly the fault will be on the CPS-A/B customs.

Nope, I didn't check anything besides changing A board itself. Maybe I'll try to reseat B board roms.
But this raises another questions - I have never personaly had any board fail to myself, but I've been collecting for a year and a half right now. I don't know how will I take it Maybe I should consider GroovyMAME setup...

This issue is specific to CPS boards and only recently we started to see these chips fail this often. No reason to believe you would also have this exact same problem with Konami or SEGA boards, for example...

OK thanks! If alot of boards die, maybe someone will come up with reverse engineered custom chip!
