Hacking Super card SD mini sd for gba

[cucho565]

Hi i just get 3 Super Card Sd mini SD and one works fine, but the other 2 when i inserted the card on the GBA i just get a small screen like the Game Boy Color type with a black frame at the bottom and doesn't load the Card Menu, i already run the test mode and everything is OK and the Sc version is 1.84, but the most rare is when i run it on a NDS it works fine but not in the GBA and i need it for that, so any sugestions???

I'll appreciate all the help. Thanks

Maybe the Supercard is pushing down the "GameBoy Color mode activation" button in the cardridge slot. It works in the DS because it hasn't this button in the slot anymore.
