(the schematics show two "right" wires), who is the "right" RIGHT?
Look in GFX/PSXTOJOY_SQ.IFF .. Pin 10 of the PIC is right and pin 4 of the db9 is right. Connect those together?
Please rephrase your question if I answered to something you didn't ask.
I've asked many questions on Amiga.org and sadly only twice have I recieved a usefull reply.
I wouldn't ask technical questions here either. ;-)
