Donkey Kong PCB Problem - I can't find anything like this

Hey guys,

I bought this Street Heat board with the hope of turning it into another DK for my DK2 project. I bought new Proms from MikesArcade.com and then bought a set of Eproms off Ebay. The board worked fine with the Street Heat proms and eproms installed but now it's all screwed up.

The screen is upside down for one, also there seems to be two images on the screen as well. The machine boots over and over again playing the Mario dies sound.

So, I took my high score save kit and installed it to see what errors it would tell me. I'll be keeping the HS kit on this board anyway for DK2. The board will boot with the HS kit installed but the picture is a mess.

I've reseated the ribbon cables, replaced the Z80 and it appears there is a rom error at 2R, would this cause this issue?

Any suggestions would be very helpful.

I ordered a couple 2114 ram ic's and a couple sockets...hopefully that does the trick. Anyone know how to flip the image though?

Thanks
