PocketNES is a popular emulator that allows you to run ROMs of classic NES games on your Gameboy Advance. It’s an opensource effort, but some fans of the emulator were upset to find that Jaleco used the emulator for a Nintendo-licenced GBA cart. However, Loopy, the emulator’s author has said thet he is fine with it. He intended for the emulator and it’s source to be completely free to whoever wants to use it. I personally appreciate his attitude and his contributions to the emulator scene.
