~80% speed improvement in decoding GX_TF_I8 textures. Yes, EIGHTY PERCENT. However, for MKWii movie playback I still can't break the fluffin' 48 FPS boundary on my machine! There's something else at play here because this decoder is ridonkulously fast.
~25% speed improvement in decoding GX_TF_RGB5A3 textures which aren't used very much. I thought it would help for movie playback but I misled myself. Video playback has nothing to do with this texture format.
Next I'll see if I can knock out some of these other texture decoders. Byte swizzling I'm sure can somehow be accomplished using _mm_unpacklo_epi8 trickery, so that'd be another big win I hope.
