R4 Ds

Can R4's be used with gba/gb roms or just DS ones? I couldn't find the answer, so any help would be appreciated =)

Thanks!

I recently bought a M3 simply DS, which to my understanding should be the same as a R4.
It will not run any GBA/GB games, only DS

Whats the best card then to buy to run GBA/GB games?
