Paper Mario: The Thousand-Year Door

Paper Mario: The Thousand-Year Door, released in Japan as Paper Mario RPG, is a console role-playing game developed by Intelligent Systems and published by Nintendo for the Nintendo GameCube. The Thousand-Year Door is the fourth Mario RPG and the second in the Paper Mario series.

Bounding Box Slowdown on NVIDIA Cards
NVIDIA cards are abnormally slow during bounding box effects even at very low internal resolutions when using D3D11. They get dramatically slower as the internal resolutions increase, even though comparable AMD graphics cards suffer no slowdown at all. This is due to Dolphin hitting a slow path on those graphics cards. It is recommended that NVIDIA users use the OpenGL backend when playing titles that require Bounding Box emulation to avoid that.

When Using Older Graphics Cards
NVIDIA GeForce 400 series and newer, AMD/ATI Radeon HD 5000 series and newer, and Broadwell integrated GPUs (Intel HD Graphics 5300+) have the full suite of OpenGL and D3D features Dolphin needs for Bounding Box - a feature this game uses for many of its effects. Older GPUs (as well as all GPUs on MacOS) lack these features, however in a workaround was added to the OpenGL backend. If you are using an older GPU on non-macOS computers, use OpenGL to avoid glitches and broken effects.

Riverside Station Sunset Effect
The sunset effect in Riverside Station has a defect where non-static objects in front of it have a trail of ghosts coming off. This is not a bug in Dolphin, but a defect inherent to the way the effect is achieved, as it appears on console too. The defect is very hard to see on console (it's right above the rock in the image below) due to the low resolution and analog quality loss, but the higher internal resolution and custom HD textures allowed by Dolphin make it very obvious.

Problems
{{Problems|{{#vardefineecho:problems|

Yoshi's Gulp
Using Yoshi's Gulp ability results in the progress bar flashing fully lit briefly, disappearing, and then the attack fails; regardless of how long the R trigger is held. Using the LLE audio back-end will resolve this issue.

Merluvee Next Path
When using the D3D backend, asking Merluvee to tell you the next path may freeze the game. This does not occur on OpenGL or Vulkan, so use them to avoid this issue.

HD Texture Pack
There is a work-in-progress high definition texture modification for The Thousand Year Door on the Dolphin forums.

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