I have two broken cps2 boards laying around. Iwas able to install this openkey but I still get the dreaded purple screen. I think installed everything correctly. I've measured the pins to CN9 top side pins and I have continuity on each pin. Is it possible that installation on my type of board is still slightly different? I tried two boards but both give nothing. The 93646B-6 gives first a little bit of black before going to purple. This vampire hunter does not seem worked on before. The other game does. Is there a way to test the components? What else can I do to try to resolve this issue. Battery hadn’t leaked and I also got a purple screen prior to the installation of the open key. My A board works with other games.
