What kind of games can download to the R4? I know you can download DS games and homebrew games, but what other games can you download to the R4?
These are the only two kinds of software that the R4 and any other slot1 device is capable of running. You can also add roms for the NES and such other systems, and use a homebrew emulator for that system to run it.
Yea, emulator games are the only other games I can think of you can download besides DS and homebrew.
Goomba is a Gameboy emulator for the GBA. Anyways, there are alot of good emu's here. http://boards.pocketheaven.com
