I've had these for awhile, so it's time to get rid of them. Both of these boards have the common "lines" problem across both slots when playing games. No battery leakage, no other problems...they both boot up and play games fine aside from the lines issue. Boards only, no metal shielding. Would prefer to sell both as a set. One has a US BIOS, the other has a JP BIOS. PM offers, thanks!
