Some news for you guys. SW scaler is done. I know it is unuseful for real playing, but for future devices It will be base. (On N900 12FPS Frameskip = 0, with frameskip 4 is playable all @ 850MHz) Sound is better, but no good. Can somebody compare sound from gpsp for psp or wiz against no$gba ? I haven´t devices for it. I am waiting for help from javispedro. I have problems with his great SDL_haa (I know problem is between keyboard and chair ) When haa scaler be done I will release it, probably without good sound in all games.
