Is it possible to play Gameboy (color) and GBA roms on Edge DS? I'd like to play the old Pokémon games and Golden Sun. I remember that I once had a homebrew app that let me boot GB and GBC roms (but not GBA), but I forgot its name. A link would be great! Also, is it possible to use a cheat system similar to that used for DS roms when playing GBX roms?
