KoF 94 Graphics Corruption

I just got a King of Fighter 94 mvs cart. Everything works great except for the fact that 4 of the teams' graphics have these discolorated and misplaced pixels. I cleaned the contacts on the cart but haven't cleaned the mobo connectors yet. Is there anything else that could cause this beside poor contact ?

Try the mobo connector cleaning...

Otherwise: try to pull the cart out of the mobo slightly(cab off) as it may make a better connection..

Do other cart work well in this mobo..?

Every other cart works fine. No sound problems or graphics problems on any other game and the problems are always with the same teams and the same frames of animation. But I will definately give the mobo cleaning a try and pull it out a little. Thanks.

I wonder if this could be a failing chip,program.

When you open up the cart do you see any EPROM'S..(windowed chips)..?

when i opened it up to clean the cart, I did not see any windowed chips. So if it is a failing chip, would it be more feasible to reburn the failing chip if I can figure out which one it is, or would I be better off buying a new cart ?

Still try the cleaning,pulling it out methods..
Curious..How tight are the boards when you tighten the case on them..?do you see any sign of warping near the edges of the pcbs..
Does the cart go into the mobo tighter then other carts..?
If so try to leave the screws a tad loose..tight enough to hold the pcbs in though..I always have to have a wobble in my carts PCBs to work right for me...I do some shaving to the Inners of the cart if I find the pcbs are warping or too tight..
As I explain here..

I do like trying to fix everything...but IMO it's easier/cheaper to buy a second cart at $10.00

Go for this one..I have bids on some of his carts because I like to have spares but I didn't bid on this one.., I've done thousands of $$ in business with him,.......... I just got a KOF 96 Large Marquee(mint) in the Mail from him today,he threw in two different Golden Tee large Marquees for free too.

And if you get a new cart you may be able to swap around the boards in both carts providing they are the same chop layout and see just what pcb is giving you the problem(bottom or top)

Thank you. I bid on the cart and hopefully I will get it. I am also getting another 1 slot in the mail tomorrow, so I can see if it is something with the mobo or the cart. I am like you are in that if I can fix it myself, I would prefer to. I actually enjoy doing that sort of thing as I am a copier technician by day. So I know what you mean. I will also give those other things a try and see if I can get it going.
