This wiki is meant to allow sharing of information and tutorials regarding the Ultra Street Fighter 4 move set editing tool known as “Ono!Tool”
The best version of Ono and the one this wiki was written for can be found here:
The tool is no longer being updated.
The modding community for USF4 (as well as SFV:AE) can be found on discord https://discord.gg/T5raMgr
There are two methods to actually playing mods.
The SF4Remix Launcher will allow you to use any modded versions of character files in USF4 or SSF4:AE (Steam Version), without it the game will hang when attempting to load the files due to a file verification checker. http://www.sf4remix.com/. Download their mod and follow the instructions for how to create your own. Remix loader will easily load and unload mods when you want to go back to vanilla version w/o having to copy/paste everything and overwrite stuff again.
Alternately you can get a modded cryptopp.dll and insert it into your root “SteamLibrary\steamapps\common\Super Street Fighter IV - Arcade Edition” folder. This will allow modded characters to load without the hassle of Remix Loader's limitations and possibly confusing instructions.
