Dolphin has now implemented Hi-res Texture loading from Loadstates. I'm considering to revisit this old project once more.
1) Standard Muramasa sprite
2) Doublesized up, and smoothed out the pixels
3) Sharpen
4) Duplicate layer that sharpens dark edges
Between 2,3 and 4, which one do you like best? I'll try to match up the rest of the body parts to that quality. I think step 4 is too much, probably a halfway point between 3 and 4 is better.
