Err... Really I don't know... Maybe gbadev forum could be a good start point to search. AFAIK you should have a flashcart or a pc<->gba cable, but in this second case, there is a limitation to the size of executables you can send to gba. More, IIRC, cable send requires a rom specifically built for multiboot, but at this time my crt0 does not allow multibooting
