Freeloader exploit
This article describes the logical layout of data on a '''Wii disc'''.
This article describes the logical layout of data on a '''Wii disc'''.
== Differences from DVD ==
Wii discs are mainly DVD based, however, to prevent piracy, they have a number of marks in their BCA, effectively nulling out those regions. All data is therefore written around these marks, also making the discs incompatible with normal drives.
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]].
