I'm looking for a GBA flash cart that's not the EZ Flash IV. I already have one of those. If you have on sitting around that you don't use, let me know.
If you can find an M3 Lite, those things are real nice. I would sell you mine, but my kids "accidentally" set the password on it and I can't figure it out yet. It works in DS mode but not GBA mode because of the password lock.
