Hi! I'am very happy owner the console Nintendo DS & DSLinker and i have question: How to other systems emulation on DS? GBA or SNES or others
to answer your question, they emulate pretty bad at the moment, but they are still fully playable. also there arent any GBA emus for NDS because the NDS has GBA playability, so no one is going to develop a GBA emu for DS when it already has that function built in.
