GameCube Main Menu

The GameCube's Main Menu, commonly known as the GameCube BIOS, is the Initial Program Loader (IPL) of the GameCube and its top level interface, allowing the player to load discs, change settings, and manage up to two memory cards at once. To access these features, the player must either hold A on controller 1, have no disc inserted, or have the lid open as the GameCube logo animates.

Dolphin does not include the GameCube Main Menu by default, and it doesn't need it; it is able to launch games straight from the Dolphin GUI. However, the GameCube Main Menu is fully functional and even capable of launching games.

Accessing the Menu
As a prerequisite, you must first dump a copy of IPL.bin from a GameCube console. Then disable Skip BIOS in the Dolphin settings. To access the menu from launching a GameCube game, load any GameCube game of the appropriate region, and hold A as the GameCube logo animates. added the ability to boot directly to the menu from the Dolphin menu.

Inserting a Disc / Changing Discs
To insert a disc or change discs, right click on any game in the game list and select "Change Disc", or use File > Change Disc. The GameCube menu has regional lockout mechanism in place, so when there's a region difference between the GameCube menu and disc, you will receive the message "The disc could not be read".

Problems
{{Problems|{{#vardefineecho:problems|

Flickering/Stretchy Menu
The start up animation and menu will stretch and distort unless XFB is enabled, either virtual or real will correct for this issue.

Missing Music/Incorrect Audio
Despite the fixes made to the DSP HLE sound by more accurately emulating Zelda ucode, music and effects in the IPL are still missing or distorted. Needs DSP LLE for proper audio. Refer.

Persistent Game ID
Dolphin will only use the game ID from the game that is being loaded first. So while changing the disc during the GameCube BIOS menu, for example, Super Smash Bros. Melee was loaded from the Game List, and then change disc and load Super Mario Sunshine, the game ID will remain unchanged. This can however result in unwanted effects such as:
 * Game settings from the first loaded game's GameINI
 * Cheats
 * Savestates
