Using the latest MSCLoader v1.2.6 at the time I'm writing this means you won't be able to remap any of the controls in this mod. The version this mod depends on is very old, and I'm not sure why it has not been updated.
When using the outdated MSCLoader version for this mod then it works almost as advertised and works really well....except the keybindings for the onfoot section gets reset every time the game is closed both in the mod and in the game settings.
It's a decent mod and is almost the perfect controller mod for MSC, but I can't keep ignoring its problems anymore
