Peach's Castle is a Tech Demo for the Nintendo GameCube. Included as part of the Nintendo GameCube Software Development Kit, the demo was used to show developers various features of the console presented in a game. In the demo, the player controls a red arrow that can go through various rooms in a rebuilt version of Princess Peach's Castle from Super Mario 64, with some limited interactivity and the ability to adjust the camera. Each room shows different graphical effects, which includes the following: large textures, bumps and shadows, anti-aliasing, local lighting, projection textures, environment mapping, and maximum polygons.

Problems

Unrecognized Disc

Peach's Castle will not load with GameCube BIOS emulation enabled, instead displaying an unrecognized disc message. Ensure "Skip BIOS" is enabled to load the demo.

Unrecognized disc error

Welcome to GameCube World Sign

A single pixel line will appear beneath the Welcome to GameCube World sign in the beginning of the demo. This appears to be the top 2px of the sign image misplaced. Refer issue 8340. This can be resolved by using the Software Renderer, but things will be really slow.

Coin Demo Room

Hitting the block in the coin demo room results in a "FIFO is Overflowed by GatherPipe! CPU thread is too fast!" error. Frequently pressing Yes on the dialog will allow emulation to continue, but it also may crash Dolphin. Refer issue 8341. This can be resolved by disabling Dual Core mode.

Video Mode Bugs

The pause menu allows for various video modes to be selected, some result in problems for Dolphin:

• 480ProgAa (i.e. 480p Progressive Anti-aliased): Results in the bottom half the image to flash between black and the expected image.
• 240Int (i.e. 240p Interlaced): Results in the image rendering squished in the top half the frame, and slid to the left.
• 240IntAa (i.e. 240p Interlaced Anti-aliased): Results in the image rendering squished in the top half the frame, and slid to the left.

Cave Lights

The Cave portion of the demo is much darker than on GameCube, it seems like there is no global illumination applied.

DirectX XFB Real Problem

Though Peach's Castle does not seem to require XFB, enabling XFB Real /w the DirectX backend causes everything to be rendered much darker than it should be.
