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.

Many prefer the GameCube version because it doesn't have mandatory Wii waggle motion controls and the GameCube version has free camera control. The GameCube version can also be patched from 4:3 to 16:9 or 48:10 widescreen; see Problems below.

Lag
Extreme slowdown may be caused by DSP LLE, so use DSP HLE.

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

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 Ghosting
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, other than to disable bloom completely using an AR code (below).

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 Patch
Enabling Dolphin's Widescreen Hack function will cause reflections to be buggy and certain objects to disappear at the edges of the screen.

Instead, use one of the following AR Codes. Remember to turn on "Enable Cheats" in Dolphin's config and use the "Force 16:9" or "Stretch to Window" Aspect Ratio.

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

NTSC-16:9 Widescreen Patch 0445391C 3FE38E39

PAL-16:9 Widescreen Patch 044558DC 3FE38E39

The following are for use with NVIDIA Surround at 5040x1050, aka 48:10 ratio.

NTSC-48:10 Widescreen Patch 0445391C 4099999A

PAL-48:10 Widescreen Patch 044558DC 4099999A

Hyrule Field Slow Down
As the player progress through the game, Hyrule Field will become progressively slower. See and. Previously, the "ZTP Hack" could be used to improve this issue. This patch has since been integrated into to the game's ini file. Fixed by.

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. Fixed by.

Useful codes
No Letterbox - This disables the unnecessary letterboxing when locking on, talking to people and entering new areas, cutscenes, etc. 04163018 38800000

No Heart Beeping Noise - This disables the low health heart beep noise which can be annoying. 042B5F98 48000124

No Motion Blur (Epona Dash) - This disables the motion blur when dashing Epona. 04181170 48000048

No Blur 0400898C 60000000 04008990 3800FF01
