A slot 1 device can definitely not play GBA roms, because then it has to emulate the GBA for which the NDS is not powerfull enough. When it is loaded on a slot 2 device, the NDS just uses its inbuilt capabilities to play GBA cartridges, and no emulation is necessary. Please correct me if I am wrong, but this is how I understand it in layman's terms,
