As the topic says really. Was working fine on both of my machines: one a micro the other an SP, but now when i turn the micro on with the supercard in, it instantly cuts out like its turning itself off. The supercard works fine still on the SP though. The Micro works normally with original carts, so it isn't the console itself. Is it the contacts possibly? I'm really stumped as to why it works on one and not the other...
