how do i get rid of them borders when playing gba games? im using ez flash 3and1 and using gba exploder!
If you're trying to disable the image displayed around the GBA screen, delete any files named "gbaframe.bmp" from your memory card.
If you're trying to get the games to play full screen on a DS, it's not going to happen.
If you mean just the black border around GBA games, you can't get rid of them. That's just the way it is.
GBA ExpLoader looks in the root of the memory card, the GBA_SIGN folder and the _SYSTEM_ folder for GBAframe.bmp, and uses it if it finds it.
If you are starting a GBA game from the R4/M3 Simply boot slot 2 button, the flashcart will look in the _SYSTEM_ folder, as well as the _SYSTEM_\THEMES\THEMEXX folders.
