UXM

When first starting the app, the default Steam location of Sekiro will be selected. If the game you want is installed somewhere else, use the Browse button to correct it.

The Unpack button will extract all files from the game archives; any files that are already present will be skipped, so if you need to unmodify any file you can simply delete it and unpack again without having to sit through the entire process.

The Patch button will modify the executable to use those extracted files instead of looking in the archives; please note that for Sekiro, most users should use Mod Engine instead of patching. Patching the executable without also unpacking the archives will crash the game, so make sure you do both.

Finally, the Restore button will restore the original executable and delete the extracted files, and the Abort button will cancel any operation in progress.

Bannability

UXM only edits data within the executable, not code, so anticheat should have no effect on it. File mods in general have never been grounds for a ban in any of the Souls games, but mods that alter your save may not be safe, so please consult your mod author's advice and play offline if using anything dubious.
