M3 DS Real Question

I have a M3 DS Real, I got the pack with the rumble pack.
Will I be able to copy GBA games into a GBA folder on the normal card and play them? Or do I needs a Slot2 expansion to play them?

You will need some sort of Slot 2 expansion or flashcart to run GBA games, not possible on just a Slot 1 flashcart.
