I don't think it's still under warranty.. I'm not sure. I bought the game the day it came out in '03, so I think the warranty's expired by now.

While on the train to Cincinnati this morning, I blew on the cartridge and the slot for it on my GBA, and, after trying for a few times, it worked. Unfortunately, while I could play the game and load files, I couldn't save anything (the game actually froze while I was in the process of saving). I turned it off, turned it back on, and it wouldn't work again. Instead, I got the "Error in backup memory" message. So, I'm inclined to believe that there is something wrong with the cartridge, since all the other games I have worked fine. I don't know how the cartridge was damaged, though, since I rarely take the game out of my GBA.

So.. anyone know how to safely clean a GBA cartridge, if at all?
