Domm has updated his port of VisualBoyAdvance SDL for the GP2x. The speed has been improved but the emulator is still unplayable.

This is a straight port of VisualBoyAdvance SDL. It isn’t isn’t very fast and there is no sound. Most of the time it rounds around 6fps. You can tweak frame skipping and other settings in VisualBoyAdvance.cfg.
