I haven't had a GBA in a long time but I still had my F2A cart. I got a GBA micro today and I put the cart in and nothing came up. Is my cart dead? I was thinking maybe the battery was dead but would that affect it loading up? It seems like they soldered in the battery so can't even swap in a new one easily. What do you guys think? Should it at least boot up? Maybe I left it blank the last time I used it.
