Paper Mario: The Thousand-Year Door

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.

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 supported NVIDIA users use D3D12 or OpenGL backends when playing games that require Bounding Box emulation to avoid that.

Problems When Using Older Graphics Cards
Bounding Box emulation 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, AMD/ATI Radeon HD 5000 series and newer, and Broadwell integrated GPUs (Intel 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.

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.
