Hey, sorry, stupid question. Probably been asked a trillion times, but I have a terrible memory. A while ago, I had a homebrew app on my Acekard 2i that allowed me to swap out the cartridge and run Action Replay codes on retail games (on my DSi). But my SD card formatted a while back, so I lost it. Now that Pokemon Black's out, I want to find it again, but I can't! I think it had R4 in the title? Or was designed for R4 use? Any help would be great. Thanks!
