Final Fight garbled graphics

[quakesin]

Hey everyone! I have a Final Fight JAMMA PCB and it's displaying garbled graphics whenever any character/object faces left. I don't know what I can do to fix this, any ideas?

Here is a screenshot:





Please help if you can

From the looks of the pictures they're using the same sprite images for facing left as right and letting the hardware flip the image horizontally. That's why the sections are in the right spot...they're only facing the wrong way.

As to why it's doing that you'd probally have to ask someone who knows more about arcade harware but my best guess would be that a "flip left" bit is stuck, maybe because of a bad trace on the board or a bad rom. That's only a guess though.

There is a guy over there that knows a lot about this type stuff(I hope he can help as he's helped me) and or repair it if needed.

It still kills me that I never noticed what was written on that door when I was a kid.

L O L!

On another note I was able to figure out that it's not the 'B' board thats causing the graphics problems it's the 'A' board. I've tested it with 2 PCB sets and both 'B' boards are fine.
