The Legend of Zelda: Four Swords Adventures

The Legend of Zelda: Four Swords Adventures is a video game in Nintendo's The Legend of Zelda series. It was released for the Nintendo GameCube in Japan on March 18, 2004; in North America on June 7, 2004; in Europe on January 7, 2005; and in Australia on April 7, 2005. The Game Boy Advance hand held game console can be used as a controller when using the Nintendo GameCube Game Boy Advance Cable bundled with the game.

Game Boy Player
NOTE: The current VBA-M version does not work with Dolphin. If anyone has either updated instructions or the number of the latest compatible version, please add.

Game Boy connection support can be supported via joybus emulation. Such requires VBA-M (r947 or newer) and a dump of GBA BIOS (see here for an excellent dump guide). To connect GBA:
 * 1) Launch Dolphin, start Legend of Zelda: Four Swords Adventures and choose multiplayer;
 * 2) While in connection screen, in Dolphin, go to Config => GameCube and change the controller ports to GBA;
 * 3) Launch VBA-M, go to Options => Emulator and uncheck "Pause When Inactive". Then, go to Options => Link => Joybus options, mark "Enable Joybus Connection" and use default settings (127.0.0.1)
 * 4) After enabling joybus in VBA-M, Dolphin will freeze (don't panic, its OK!). Now load the GBA BIOS in VBA-M, after the splash screen Dolphin will recognize the joybus link and game will detect that a GBA was connected.

To connect other GBAs, just open another instance of VBA-M and repeat last instruction. Remember to unblock Dolphin and VBA-M in your firewall, some may block joybus link, leaving Dolphin stuck in connection screen. You can also refer to this video for more details.

Multiple GBAs
HLE audio can only support 1 GBA as of the New-Zelda-HLE rewrite. Use DSP-LLE (with a DSP ripped from a Wii/GC) in order to play with multiple players.

Navi Trackers requires DSP-LLE (with a DSP ripped from console) in order to function properly

HLE Sound Hang
With DSP HLE enabled, when the frame rate is below 60FPS sometimes one soundtrack will loop or hang causing all other sounds to be muted. Refer. To avoid this, use DSP LLE. Fixed by.

Z-Order/Transparency Issues
Some sprites, primarily trees, are not ordered/transparent appropriately and layer on top of the player sprites. Refer. Fixed in.

Odd Glitches
