How to play GBA games on supercard DS one

please, i want to play KH COM in GBA after playing days i want know the story, i downloaded the ROM insert it to my supercard, but it freezes at gamboy advance logo! please help!!

You need a Gameboy supercard pak then you can play it.I don't think they sell it anymore so the best way is to order it or to buy the real game. or just et the emulator andget the rom and play it so you don't waste money ;D

They still sell it.Hard to find...

Just play it on an Emuator like I do.

That is another good option.I think it is possible to use an EZ Flash with it, using GBA Exploader.
About 5-10 USD less than super card GBA.
