I have begun making reproduction carts of SNES and NES games but now I want to make some GBA games. I have seen programmers/burners (not sure what it would really be called for GBA) that allow you to plug an SD card with roms on it into a GBA and burn the rom to a cartidge. I have done quite a bit of reading and learned that you can reflash/rewrite over many bootleg GBA games to pretty much make reproductions using a $2 bootleg game. I have an XRom but I can't find any info on how to use it for this. Pretty much, I want to either use the XRom I have to reflash bootlegs or use a .nds program to reflash bootlegs. I figured it would be possible since the 3n1 program flashed roms onto the specific 3n1 cart but it doesn't even let you try with bootlegs. With the XRom device, I know it should be possible but I have no idea what program or drivers to use, I have just heard of it being done with no info on how to.
