Game Boy Advance <-> GameCube Connectivity
NOTE: Some versions of VBA-M may not work properly with the latest version of Dolphin. To ensure compatibility, make sure to try various revisions of VBA-M. The version of Dolphin after the GBA <-> GCN rewrite does not matter.

This title supports GameBoy Advance 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.

Navi Tracker Audio Issues
VBA-M does not correctly handle the audio from the Navi Trackers mode. This is not a fault of Dolphin, as a modified version of mGBA does not share the issues and works properly.

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.

HLE Navi's Trackers Hang (JP version)
When using HLE audio emulation the game will hang when trying to use Navi's Trackers mode /w a GBA. Navi Trackers requires DSP-LLE (with a DSP ripped from console) in order to function properly.

16:9 Aspect Ratio Fix
The Built-in Widescreen Hack does nothing in this game. The following Gecko code works as a replacement.
