GBA Roms at R4DS?

Is it possible to play GBA Roms at your R4DS?
Last time I downloaded The GBA version of WariorWare. After that, I made a NDS-File of it.
But when I tried to play it, it wouldn't load. :'(So is there a answer to sole this, or isn't it possible? :o Please report me ;)

Using just an R4DS? No, I'm sorry. When the DS plays GBA games, it forgets it is a DS, which means it doesn't know it has a DS game slot which means that it can't read the game from the DS slot. The other problem is that the DS slot is too slow. The GBA plays the games directly from the cartridge and doesn't have to load. The DS loads from the game card. Hope that made sense to you. If you want to play GBA games, get an M3 miniSD or lite (microSD).

get the ez-flash 3 in 1 expansion packrumble pack, opera ram pack and one full gba game at a time

If you have a PSP, play your GBA roms on that. So much better...

I use a EZ Flash 3-in-1. Use NDStation to patch it. Works a charm.
