So I recently put a VA 0 Saturn I've had in pieces back together again and I'm having a weird issue. Everything works perfectly with the top off. With it fully assembled though it doesn't validate game discs, it takes quite some time and then decides it's not a genuine disc. To make things even more weird the CD break even spins the disc backwards with the top on. The top case doesn't interfere with the disc in any way that I've found out. Does anyone have any idea of what could cause this?
