-set wiiflow version to beta 4.2.2 -added another memory manager just for wii games and banners -changed THP file playback, for sound you now need to have a ogg file with the same name, that fixes all audio shutters and crashes -optimized THP file playback and JPG extraction alot, it should now work fine with 640x480 30fps without any crash or freeze anymore
