'''main.dol''' is the name given to the main executable of [[Wii]] and [[GameCube]] games. It is not a named file on the game disk, but rather the name given to the section of the disk containing the main executable. It uses the [[DOL (File Format)|DOL format]]. [[Mario Kart Wii]]'s main.dol contains quite a lot of generic library code, but most of the game specific logic is in [[StaticR.rel]].

main.dol is the name given to the main executable of Wii and GameCube games. It is not a named file on the game disk, but rather the name given to the section of the disk containing the main executable. It uses the DOL format. Mario Kart Wii's main.dol contains quite a lot of generic library code, but most of the game specific logic is in StaticR.rel.
