R4 + GBA ROMS = massive frustration...HELP please

i recently got my r4 and using youtube figured how to play nds games but i've zero luck finding out on how to play gba games on it. is there any simple way to play gba roms without having to download an emulator or some homebrew app. i'd really appreciate a step by step approach to this problem.

You can't play GBA ROMs on a Slot 1 flashcart.

dam thanks i guess i need to buy some thing else.

Yes a Slot 2. Check out gbatemp.net and then Reviews.

Thanks man u really helped because there's a lot of gba classics i wanna revisit.
