The aim of these graphics was to fix a lot of the sloppiness of the original player graphics but keep it as close to the original in style and posing as possible. I've done my best to eliminate coloring inconsistencies, ugly shading, and poor readability. Also as alternative options you can have more shading on Mario's shoes and gloves.
The .zip includes:
GFX32.bin*3 (three of each for alt. options mentioned above)
Shared palettes for both levels and overworld
