Sonic Adventure 2: Battle

Sonic Adventure 2 Battle is the Nintendo GameCube adaption of Sonic Adventure 2 for the Sega Dreamcast and was released on December 10, 2001 in Japan, February 12, 2002 in North America, and on the GameCube's launch (May 3, 2002) in Europe. This game is also the first Sonic the Hedgehog game on a Nintendo system, having been released ten days before Sonic Advance in Japan. It was later followed in 2004 by Sonic Adventure DX: Director's Cut.

Tiny Chao Garden
Connections to a GBA (emulated via VBA-M) to enable play of "Tiny Chao Garden" does not work. Dolphin will not connect.

Black Bar at Bottom of screen
This is caused by the game running in 50Hz Mode. Hold down B as emulation starts to get a prompt for 60Hz Mode.

Crash in Wild Canyon (2nd Hero level)
If framelimit is set to "auto", then the game will crash upon the player trying to float up using the wind tunnel in the middle of the level. Setting the framelimit to "60" should do the job.

Random FPS drops
Some levels (notably City Escape) will sometimes seemingly out of the blue drop the framerate to about half of regular speed. The cause is unknown.
