If you wish to start modding it's recommended you utilize these modded files that fix numerous bugs in USF4 as the basis for your mod. It also features the dll file that will allow you to load mods.

There are two main to actually playing mods.
The USF4 Simple mod launcher is an easy to use mod manager. When using USF4 Simp you put the folder for your mod (E.G. ModXYZ) into the main folder of USF4 “SteamLibrary\steamapps\common\Super Street Fighter IV - Arcade Edition.” The inside of the ModXYZ folder should contain all of the files from “patch_ae2_tu3” including the 'battle', 'movie' and 'ui' folders. For the modded character files you put them in “Super Street Fighter IV - Arcade Edition\ModXYZ\patch_ae2_tu3\battle\regulation\ae2_110” and “Super Street Fighter IV - Arcade Edition\ModXYZ\patch_ae2_tu3\battle\regulation\ae2_111” rather than splitting them between patch_ae2_tu2 & tu3 you simply put ae2_110 & ae2_111 into the 'patch_ae2_tu3\battle\regulation\' folder inside your mod.
The most up to date version of USF4 Simp is “0.0.7651.26748”
Alternately you can get a modded cryptopp.dll and insert it into your root “Super Street Fighter IV - Arcade Edition” folder. Doing that will allow you to launch modded character files without the game getting stuck on the loading screen. Overwrite your cryptopp.dll in the SF4 root directory and then you can simply modify the .bac & .bcm files located in the “patch_ae2_tu2\battle\regulation\ae_110', and 'patch_ae2_tu3\battle\regulation\ae_111' folders.
