The Legend of Zelda: Twilight Princess (GC)

In The Legend of Zelda: Twilight Princess, the next chapter in The Legend of Zelda series, Link can transform into a wolf to scour the darkened land of Hyrule. With the help of Midna, a mysterious being, you must guide Link through hordes of foul creatures and challenging bosses using new moves and a new horseback combat system. Many puzzles stand between Link and the fulfillment of his quest, so you must sharpen your wits as you hunt for weapons and items.

Hyrule Field Slow Down
As the player progress through the game, Hyrule Field will become progressively slower. It has to do with how the game works, and there is no solution at this time. See and.
 * Previously, the "ZTP Hack" could be used to improve (not fix) this issue. However, it was removed due to incompatibility with an upcoming code change, and it will not return. If you are experiencing severe speed issues and wish to try the hack, it is available on and all versions prior to.

Sound Issues
Sound problems may occur with the DSP HLE audio plugin. To correct these problems, use DSP LLE.

Minimap

 * With EFB to Texture the minimap will become unusable after a transition into another area, showing nothing but visual garbage. Use EFB to Ram to fix it.
 * The minimap requires Texture Cache Accuracy to be set to position 1 (Safe), otherwise the arrow will become confused and fail to follow Link as he travels.

Bloom
Due to the low resolution bloom, a "ghost" image will appear around certain objects in areas with high amounts of bloom. There is no known solution.

D3D Darkness
With the D3D graphics backend the lens flare from the sun is glitched. When looking at the sun through trees of buildings, part of the effect shows through, displaying a small lens flare and an overall darkening of the screen. Only the D3D backend has this problem, so use OpenGL to avoid it. See.

Sun Rays
Twilight Princess uses a ray effect at various points throughout the game, most notably at windows and the fountains. The effect is very easily broken. How it is broken depends on the backend used:
 * D3D - Anti-aliasing and an Internal Resolution above 1x Native damage the effect
 * OpenGL - The GLSL merge (3.5-1025) greatly improves the effect in OpenGL. It is now only affected by Anisotropic Filtering and an Internal Resolution above 1x Native.

Widescreen Hack
Enabling the widescreen hack will cause reflections to be buggy and certain objects to disappear at the edges of the screen.

Better to switch off the widescreen hack and use one of the following AR Codes instead. Remember to turn on "Enable cheats" and use the "Force 16:9" or "Stretch to window" Aspect Ratio.

Note: Use the NTSC codes if you're running the USA or Japanese versions of Twilight Princess. Otherwise, use the PAL codes for the UK, Europe, etc.
