The GameCube and Wii check for these marks on disc boot by checking for null regions. Homebrew discs can therefore identify as Wii discs by nulling out these regions through software, although some software may need modification to avoid warning messages. [[Freeloader]] exploited this to not require a [[drivechip]].
