Pretty sure my battery died even though I hardly used it and only got it at christmas. I'm wondering how long these things are supposed to last and if there is any replacement that lasts for many years or is rechargeable. Can anyone link to a guide on how to replace the battery aswell? all the pics are gone in the thread from 09. I'm using it with an r4i 3ds gold and that saves DS games fine to the memory card. Any way to somehow save the GBA games to there?
