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.

Emulation Information

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. This happens on console as well and a replacement BIOS (such as Swiss) must be used.

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 is more visible at higher Internal Resolutions. This appears to be the top 2px of the sign image misplaced and occurs on real hardware. Refer issue 8340.


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 and issue 7143. This can be resolved by disabling Enable Dual Core.

Cave Lights

The Cave portion of the demo is much darker than on GameCube, it seems like there is no global illumination applied. Refer issue 8360, fixed in 5.0-7151.


Only configuration options for the best compatibility where they deviate from defaults are listed.


Config Setting Notes
Enable Dual Core Off Prevent FIFO error/crash in coin demo
