When Nightmare Zero was making his 32-bit Sigma sheet we had the idea of re-making 16-bit Sigma sprites APPEAR to be 32-bit be adding more shades on Photoshop. However, when I finished the job, it turns out MUGEN chgaracters can only have a certain number of colors and these exceeped that limit .... by a great deal. Rather them going completely to waste, I've posted them here. The origional sheets were made by Heatman. These sheets were a bit irritating to make, so ask before you go on a shopping spree.
