The '''Pre-Repair Check Disc''' is a software disc used by Nintendo repair centres circa 2009 to check for the presence of unsigned content on a Wii system, and refuse to allow a repair if it is present. Upon starting up, it checks if an [[Wii Development Hardware#NR%20Checker|NR Checker]] is connected to GameCube controller ports 3 or 4 before continuing. If missing, the program calls a function to eject the disc. The source code for the disc's software was found in [[wiidump.7z]], at the following path:
