Other thing who took much time is resolution. MUGEN don't process files with 2.048 MB(2GB) and images in 1280x720 uses 2.7GB. My solution is use half res(640x360) to compress for a minor file(435 MB).
This can be downloaded in Misc section.
This is my heaviest work for now, because i need recreate various images to make them 256 colors and put darkest pallete color as alpha. ...
