How do I get GBA roms to play on my DS???

I have a Super card DS One and and the scshell program installed to run DS roms. Im new to this DS roms thing and I tried playing GBA games with the scshell program and it wouldnt let me. Is there a program I can download that would let me play DS and GBA roms or do I have to buy a GBA hardware cartiridge like my Super card to play GBA games ? :P

I didn't understand that one bit ???

You can't. You have to have a slot 2 card with RAM. Don't ask "but is it possible with "blah blah blah card"". (Double quote :o) Just check and see if it has extra RAM. There no slot 1 cards with extra RAM.

But what about my uber1337 R4 DS? surely it can.only joking btw....
