I have kept this at home for many years. I have confirmed basic functionality on a Game Boy Advance SP. *Please note that compatibility varies with the actual device, and I cannot guarantee 100% functionality, nor can I guarantee continued operation in the future. To prevent swapping, returns are generally not accepted. Due to shipping costs, there may be a change between Yu-Yu Mercari Delivery and Raku-Raku Mercari Delivery. Please purchase only if you agree to these terms.
