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
Much like Sonic Heroes, non-native internal resolutions or anti-aliasing will cause white stripes to appear on the top left of the screen.

This can be worked around by disabling Scaled EFB Copy and setting the internal resolution to 2.5x, 3x, 5x, or 7x. But there is limited benefit to using this; unlike Sonic Heroes the game uses a screenspace blur effect for depth of field, so, without scaled EFB Copies the higher resolution does not help as much.

One negative of this method is that it can't go above "640x480" internal rendering resolution, so this solution is not ideal for those seeking HD quality.

16:9 Aspect Ratio Fix
The built-in Widescreen Hack causes clipping issues. The following AR codes work as a replacement, causing fewer issues. To avoid conflicts, make sure that Widescreen Hack is disabled while using these codes.
