Folks, all I want is to finish my project. Now, the board is effin up. Board was testing and working, when I bought it and it came from a KLOVer, so I knew the Ohio valley was ok to trust! ;)

At the attract mode, I can clearly see the 1983 NOA logo at the bottom. However, the actual "Mario Bros" logo that drops down, is all messed up and seems to be upside down. Credit/High score screen reads fine, but Mario and Luigi are sprites and blobs. Same in the board mode. Cannot distinguish shellcreepers or characters, yet all wording is there. Colors seem to be ok also. Odd.

Does this point to a bad video chip? If so, which one? I'm holding off getting replacement ones, but it seems to be pointing in this direction. Ideas?

I can send pics later, if necessary.
