More skin is always welcome, don't you think?

Mod doesn't include the color files as it's built to be used in its vanilla costume slot.
If you want to use in another slot you got to get the color files from the main game folder at ...\Steam\steamapps\common\Super Street Fighter IV - Arcade Edition\resource\battle\chara\SKR

To install this mod, just drop the contents of the zip file inside your game folder at:
...\Steam\steamapps\common\Super Street Fighter IV - Arcade Edition\patch_ae2_tu1\battle\chara\SKR

If this folder doesn't exist, just create it.

The mod shouldn't overwrite any file, but make sure to have a backup of your original files before installing the mod.
