The manager functions by copying the contents of enabled mod folders to the root of the game before launching, allowing the user to avoid lots of manual work in managing their mods. This is a simple mod management utility for the Naruto Shippuden: Ultimate Ninja Storm games, 3, Revolution, and 4 specifically, based off of MainMemory's SA2 Mod Manager.
