I bought an unused CPS2 multi from a friend. Got everything installed including the key writing. Upon boot, the multi flashes a game, it starts briefly then resets and starts flashing again. I was using the longer cable to connect the LCD. Swapped it for the short cable and everything works perfectly. Retried the long cable and it's still faulty. Just wanted to post to say if anyone experiences such resets it may be a bad cable.
