Sonic Colors

Sonic Colors (ソニック カラーズ Sonikku Karāzu in Japan, Sonic Colours in European and Australian markets) is a 2010 platforming game in the Sonic the Hedgehog series. The game has similar gameplay to the 2008 game Sonic Unleashed, using both both side-scrolling and third-person perspectives.

Odd Spring Textures
In OpenGL, springs appear with weird textures, even when turning on Safe Texture cache (though, when turned on, it TEMPORARILY solves the texture problem).

OpenGL Startup Screen Hang
In OpenGL, the game may hang after the SEGA logo if you have EFB Copies enabled at game startup. Disabling EFB copies resolves the issue. However, EFB copies need to be enabled for proper emulation. To fix this, either use DX9 or DX11. If using OpenGL, you can disable EFB copies when starting, and re-enable after the main menu appears.

Boost Effect
Some people have reported that boosting causes a large portion of the viewable area around Sonic to go completely black, making navigation quite difficult, though this bug does not affect game performance. It seems to happen mostly when the internal resolution is set to above 1x native (640x528).

Low Performance Crash
If running the game with low performance computer with low FPS and slow emulation speed, the game may crash after Sega title cutscene. You can use "accurate v-beam emulation" to help with this.
