Sonic Heroes

Sonic Heroes is yet another installment in the Sonic series for the Nintendo GameCube. In Sonic Heroes, three characters (in teams, of which there are 4) travel together at once, each with unique abilities which the player can utilise to defeat enemies or tackle obstacles.

Black Areas
Odd black areas appear on the right side of the screen in-game on all backends. As of, the core problem has been partially addressed, see and the April Dolphin Progress Report. However, the problem still occurs if using resolutions above 1x Native, using any level of anti-aliasing (none is bug-free), or messing with the Scaled EFB Copy setting. Under OpenGL only, if you change Anisotropic Filtering during emulation, multiple shadows appear. Changing it back either to the default setting (1x) or the original setting you had it at doesn't fix the issue. It requires the emulation to be stopped and then restarted for the setting to take effect.

Corrupted UI elements
Some of the UI elements appear corrupted. Notable examples are emblem counter and the text on the save data loading screen. Setting Texture Cache Accuracy to Safe solves this issue.

Controller Issues
In two player mode, the in-game controls for pressing A, B, X and Y act as if they are set to turbo-mode (holding the button down means the button is repeatedly turned on and off very quickly). This makes gameplay very difficult due to not being able to jump high enough, rapid scrolling through the characters in the team, and so on.
