Hi all, hope someobody can help me on this issue. I have heard of the case where gba cartridges will lose their ability to save as there is an internal battery that will drain out after sometime. Thus, I am looking for a simple way to backup the games onto the PC and transfer the game back onto another media that I can attach it to the GBA SP and continue playing without touching my original cartridges. Alternatively, is there a way to change the battery inside the cartridges once it is drained out? And is it possible to DIY? I have amassed quite a collection of GBA games and I don't want to end up not being able to save a game because of some battery issues. Thanks for any help rendered!
