I'm trying to find a way to get action replay codes to work with my slot two carts. I have an EZFlash IV, and can run it in NDS mode with my R4. I don't have high hopes for that though, it's mostly just there to connect to the gamecube. I also have a 3in1, and my hopes are a little higher for cheating. Again with the R4, what software do I need to use cheats for GBA roms? Is it even possible with the hardware I have? And with the 3in1, is there a guide for setting up the screen borders for gba games? The black border doesn't bother me, but it'd be nice to change it.
