Shadow the Hedgehog

Shadow the Hedgehog is a 2005 video game developed by Sega Studio USA, the former United States division of Sega's Sonic Team. Featuring the titular fictional character Shadow the Hedgehog from Sega's Sonic the Hedgehog series, the game was revealed at the March 2005 Walk of Game inauguration of Sonic, the series' main character. Shadow the Hedgehog is the third game (and the last in the Sonic series) developed by Sega Studio USA, which was merged back into Sega's Japanese division in early 2008.

2 Player Mode
2P mode is playable only with EFB Copies to Texture Only disabled, otherwise the right screen is messed up.

White Stripes (Direct3D)
Non-native internal resolutions and anti-aliasing cause white stripes to appear on the top and the left of the screen at certain points of the game under Direct3D. This can be fixed either by setting internal resolution to 1x Native or disabling Scaled EFB Copy and setting internal resolution to 3x Native or higher. OpenGL doesn't seem to exhibit this problem.
