BCP (File Format)

The BCP (Binary Camera Parameter) file controls the opening camera around the character before the countdown in Mario Kart Wii. There are four BCP files found in Mario Kart Wii. All of them are found into Common.szs. The files are battle_camera.bcp (used for battle), mission_camera.bcp (used for widescreen Competition/Tournament), race_camera.bcp (used for Grand Prix, VS Race, Time Trial and most Competitions/Tournaments) and start_camera.bcp (unknown). All these files found in Mario Kart Wii are 0x130 bytes long.

File Format

The file byte order is always big endian, and it is always 0x130 bytes long.
