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
On OpenGL and D3D11, NVIDIA cards are abnormally slow during bounding box effects even at very low internal resolutions. 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. Thankfully, the D3D12 backend doesn't run into this issue on NVIDIA cards, and provides performance equivalent to likewise graphics cards.

It is recommended that NVIDIA users on Windows 10 use or newer and the D3D12 backend to prevent slowdown and CPU/GPU desyncs caused by said slowdown. For non-Windows 10 users, a similar speedup is being worked on for OpenGL.

Problems When Using Older Graphics Cards
Revision introduced changes to the Vertex Loader JIT implementation of Bounding Boxes. This change requires GPU-specific features that are not present on older GPUs (older than 3rd quarter 2012). As such, graphics cards without Direct3D 11 or OpenGL 4.3 support are no longer supported. In essence, only computers with GPUs: Nvidia GeForce 400 series and newer, ATI Radeon HD 5000 Series and newer, and Broadwell integrated GPUs (HD Graphics 5300+) are supported by Dolphin for games requiring certain bounding box implementations. Using newer revisions with unsupported GPUs will lead to graphical glitches and softlocks. If game-breaking bugs are experienced, use revision or lower as a workaround.

Requires Bounding Box
A large portion of this game requires bounding box emulation. Without bounding box emulation, there will be graphical errors, crashes, and other issues throughout the game. It is not recommended to ever disable bounding box emulation while playing this game.

Glitched Transitions
Most transition effects will show only garbage. Disable EFB Copies to Texture Only to prevent that. Note: In some cases the game will actually crash if you have EFB Copies to Texture Only enabled.

The error occurs if the player talks to Merluvlee and asks for where to go next.

JITIL Crashes
JITIL causes crashes at battles. Use JIT to prevent that. Fixed in recent development builds.

Professor Frankly's Gate
The gate outside Professor Frankly's house turns into a cyan block, and then disappears when he is opening it to show you the Thousand-Year Door. Fixed in.

Background During Pageflip
In the castle in Chapter 1, and there's this switch puzzle where Koops are used to hit a block. Walls become improperly transparent behind where the stairs move to. Refer. Fixed in.

Improper Water Effect
After Stone Key Quiz and going through a pipe into the sewers, the water reflections are a bit messed up depending on where you walked. Refer. Fixed in.

Chapter 3 Posters
In Chapter 3, when you peel the posters off the walls, they show up improperly and look weird, sometimes casting blackness over the wall, sometimes showing up as a tiny piece of a poster, and sometimes drawing over geometry they shouldn't be. Refer. Fixed in.

Punies
The Punies may display incorrectly on all backends. EFB Copies to Texture Only displays garbage, but with it disabled the Punies are distorted. It only happens when they are standing still, and seems to happen more when they are facing left and not right. See. There is a workaround using a custom texture to replace the garbage. Fixed in.

16:9 Aspect Ratio Fix
The built-in Widescreen Hack causes clipping issues. The following AR codes work as a replacement, causing less issues. To avoid conflicts, make sure that Widescreen Hack is disabled while using these codes. This code also speeds up the emulator in the Shhwonk Fortress.
