Hi!
I'm hoping someone has seen this problem before. I recently installed a duo chip in a PS2 ver 4. With the chip activated I cannot boot any games at all, back up or original. With the chip disabled the PS2 boots as normal. I installed the chip next to the ground pad, ran 20-22 awg wire for power and 30 awg for the other wires. I also have ohmed out the wires looking for faulty connections and shorts. Is there any way I can check to determine if it’s the chip or the wiring that is at fault? Any advice/help would be greatly appreciated.
Thanks in advance.(and thanks for all the helpful advice on this board!)

If the PS2 boots originals with the chip deactivated but doesnt boot anything under power i would say you got a wire crossed. Obviously you got power to the chip and usually if you have a bridge it wont load anything including originals so recheck all pins.
