I've been looking for an NDS file that, when run, will boot whatever GBA game is in slot-2 and slap on a custom border instead of the default blackness that the NDS has. I know it can be done, as even the R4 is capable of it. I know GBA ExpLoader can do it with the proper config, but I'm looking for an instant-run program that just boots the slot-2 without further questions. Note that I am NOT looking for a program that patches the borders into GBA games.
