Okay well, i'm trying to flash the expansion of Daigasso! Band Brothers onto my GBA cart but it says it's not a valid rom. The file isn't broken and I'm not flashing it wrong, I'm using EZFA, and EZFA Client 1.00 beta4. Thanks. Oh and also, could anyone suggest a (normal) DS flash cart (I don't have a DS Lite)? I'm trying to get the best one, as in, best compatability, easiest to use, etc.
