Hi, I don't have an R4, but should be getting one soon. I was wondering if it would be possible to use the R4 to apply cheat codes to official GBA games (not gba roms) using the DS. Or perhaps is it possible to transfer save files from the GBA to the R4? I mainly wanted to use some codes on Super Robot Wars OG2 US version if the game matters. Having a hard time beating this game cause I can't get the game to soft reset when I switched to a DS lite.
