Hey guys, I finally found a Raiden bootleg PCB (don't ask me why I wanted this, I already have an original) but it has some weird graphics issues with it (some characters are blue instead of white and parts of graphics appear behind parts of other objects. Before looking into this in more detail, I managed to get it into test mode (P1+P2 start buttons on power on) and got the crosshatch and the controls testing. Is there anything else that can be tested in the test mode? I am more interested in IC/ROM/RAM testing.
This happens to be a Korea license bootleg with most of the EPROMs soldered (so can't be tested good/bad). It also has a burned GND and 5V edge (managed to repair that though).
Thanks!
