On it's own-no r4's can't do it. A slot 2 card uses the gba cart slot, the most commonly and best to use is the ezy 3 in one. It's not emulating gba, the games stored in the r4 are just being booted in gba mode thanks to the ezy 3 in one flash cart. Post Merge: [time]1269948420[/time] "slot 2 button"-Prehaps you press that to access a slot 2 card inserted, try throwing in a random gba cart and see, though an ezy 3 in one (unless it's booted a game and saved it into it's self) won't be recognised.
