Changes

To boot the GameCube's original BIOS, you need a dump from real hardware. Dolphin does not require it to load games but can be set to use it if desired. Current development builds have introduced a feature allowing users to load the BIOS directly from the interface in the Tools list without needing to load a game, as well as hybrid XFB. If you're on the current stable release, use XFB Virtual and disable "Skip BIOS" in the GameCube options; you will have to load a GameCube title so that the startup animation begins, and like on the original console, you hold the first controller's A button down and the system will send you into the main menu instead of booting the game. You can then switch to another game with Change Disc, or you can explore the BIOS.

Dolphin includes a GBA core based on [[mGBA]] that is tied to GameCube emulation, which allows for a very stable connection that works with features such as save states and netplay. Dolphin can also connect to standalone versions of mGBAor [[VisualBoyAdvance-M]]; this is necessary for some less commonly used features such as [[GBA e-Reader emulators|e-Reader]] support or cases where the GBA has to be disconnected from the GameCube. Both of these can be enabled by going into the controller settings and assigning the GBA to one or more ports. The general config menu also allows you to specify a GBA rom to be used if using the built-in GBA core.

This add-on plugged into the bottom of the GameCube and allowed it to play Game Boy / Game Boy Advance games on a standard television; it had provisions against [[Wikipedia:Game Boy Advance Video|Game Boy Advance Video]] cartridges by returning an error after booting them. The launcher even had support for the GBA-GCN link cable where the Game Boy Advance would serve as the controller. Some GBA games like ''Super Mario Advance 4'' and ''Mario & Luigi: Superstar Saga'' took advantage of the add-on by adding rumble support. The hardware is essentially a peripheral containing Game Boy Advance hardware. A GBA BIOS file is required for this to work.

This was an accessory bundled with ''Mario Party 6 & '' and ''Mario Party 7'' that allowed the GameCube to receive audio from the memory card slot. There were also other games known to support it.
