My treasured lifeforce pcb has developed graphics glitches/garbled graphics. The game is running fine in the background.
I have spent days checking all the usual problems with no success (voltages, ram, roms, logic ic's), and have reached the point where I need a circuit diagram/schematic to carry on. I have searched loads of sites, but cant find one. The nearest i can find is a nemesis circuit diagram, which shares the same graphics board, but i really need a diagram for the top board, which is a gx587.
Please can anyone help me out with a schematic? I would hate to have to scrap my favourite board!
