I have a Virtua Cop 2 that comes up but has random polygon garbage all over the screen -- sprites & text overlay is working fine. Nothing I haven't seen before, but according to system16, VC2 uses a unique video board..
I have a couple working Dynamite Cop sets; I could sacrifice one if necessary.. but is the standard 2A-CRX video board incompatible?
If that is the case, I'd trade a working DC for a working VC2..
