Final Fantasy Crystal Chronicles

Final Fantasy: Crystal Chronicles, Square's first game for a Nintendo console since the days of the SNES, takes the lush fantasy world from the Final Fantasy franchise and adds in hack-and-slash-style four-player action. The game does away with traditional experience points and instead focuses on action-oriented combat with a unique co-op slant. Up to three friends can join in on the quest, by using Game Boy Advance units connected to the GameCube as controllers. While all the main action takes place on the screen, the GBAs enable the players to access menus, organize their spell spheres, and perform upgrades without slowing down the action. The initial release of this game included a GBA Cable to allow players instant access to the game.

Multiplayer Support via VBA
Multiplayer support via Visual Boy Advance connectivity works. But is very slow even with only a single instance of VBA-M connected. Refer.

To set up multiplayer with VBA-M, follow these steps.
 * Download the latest VBA-M svn.
 * Dump your gba_bios.bin, and enable it in VBA-M (Options > Emulator > Bios Files)
 * Disable "Pause when inactive" in VBA-M (Options > Emulator)
 * In the Dolphin configuration, go to the "GameCube" tab and select "GBA" for port 2
 * Start the game in Dolphin and go to a dungeon
 * In VBA-M, go to Options > Link > Joybus Options and type "127.0.0.1"
 * When you press ok, Dolphin should freeze (this is normal)
 * Now load the gba_bios.bin, in the same way you would load a normal gba-game (File > Open GBA)
 * Enable Turbo Mode in VBA (Options > Speed > Turbo Mode), otherwise the game will run at ~8% speed
 * Now just wait until it connects. It may take a while, but this is normal
 * You can use a VBA-M savestate to make it connect faster next time

Audio Problems
The game's music often becomes distorted after playing a few hours and on slower computers the music can become desynchronized. Fixed by the New-AX-HLE 2.0 merger in.
