I've had my M3 Real for a while now, which came with the GBA expansion. I've always played GBA games, but there was one huge problem, very few games actually saved as they should (and I don't mean RTS, I mean regular saving). One of the games that NEVER worked, not even with RTS, was Castlevania - Aria of Sorrow, at first I thought it was just a software problem, but as I kept upgrading to newer versions, the saving part was never fixed... After reading about people with similar problems here on the GBAtemp forums I thought the only reason was that my expansion was busted... So I managed without my GBA backups. But a few days ago I've decided to try out the new Sakura (the translated english version) to see if it was any good, and guess what? All the GBA games I've tried so far saved flawlessly (even Castlevania), and so far the saves haven't been deleted randomly like they used to. It's been almost a week and no problems at all! I'm just wondering if someone has any explanation for this... It seems my expansion was not busted after all, oh and I did try saving GBA games one more time just before switching to Sakura, and it never worked. For this reason alone I'm loving Sakura so far, and it hasn't given me any problems at all with either homebrew or DS backups.
