I'm currently in the need of a GBA flashcart that I can use with my GameBoy Advance SP and my GameCube. I've done about 10 minutes of research and I've come to the conclusion that there were some flashcarts that had imperfect GameCube compatibility. This means some flashcarts work with certain games but not others. The game I'm particularly interested is Pokemon Coloseum with the transferral of Celebi and Jirachi using the bonus discs. I understand that GBA flashcarts are becoming rare because less people are playing GBA games so please help me by posting any experience you have and if you can recommend GBA flashcarts that work with this title. Currently, I'm confident that the M3 Lite works well with the Pokemon games but it's a bit costly. I've always had my eye on the EZ Flash IV but I'm not confident it's compatible with Pokemon Coloseum. It seems the transfer of Pokemon always fails and even corrupts the save file.
