[nonosto]

Hello

I have this at the boot on my ssf2x convert rev 7 b board:

the romset run on other board, I have one scratch on way under socket number 7:

do you think this is it or a ram chip dead? Or somthing other?

THX

I don't think there's a damage on traces on your photo. Try to reset boards A and B, if still happen, replace obj ram.

Howdy. I'm having a similar issue on an old 18-1 bootleg board. I wanted to confirm the chips for object ram are the ones located in the picture at 3A and 4A (HM6264A-10)

If it's just the 2 chips I'll just replace them both.

Answer my own questions: issue was the top left portion of the board (jamma edge on left) found by applying pressure. Reflowed everything near that area that was part of a connection, like the pins on the multi and the a/b board connectors.
