03

To do: Add unused code. Figure out the .gpl model format.

GameCube Service Disc v1.0/03 was once used by Nintendo World Class Service to test and diagnose problems with the console, Memory Cards, controllers, and can even check the currently-inserted Game Boy Advance game through the GameCube-Game Boy Advance Cable. Nintendo 64 controllers can also be detected, suggesting this is from earlier in the console's development.

As with all Nintendo testing software, the Service Disc contains a plethora of Nintendo-themed content, both used and unused. Bizarrely, there are also respectable logos from the automotive industry, such as Tamiya and Goodyear.

Console revisions post-2003 will boot the Service Disc to an indefinitely-hung black screen, likely done to prevent further servicing after the demise of the Nintendo World Class Service. Remaining copies were taken back by Nintendo and presumably destroyed; as such, few copies saw the light of day.

Unused Music#

Loads of unused music is present on the Service Disc.

audio#

sab32.pcm is Otis Redding's "Sittin' on the Dock of the Bay", which was likely used for testing.

audiosys#

Two unused songs are present in this folder. They are the same track at different sampling rates, 32 kHz and 48 kHz respectively.

Car3230.adp and Car4830.adp - Also could have been intended for the car demo intro.

CarDemo#

Duplicates of Car3230.adp and Car4830.adp are present in this folder.

cardemoA.adp - Also could have been intended for the car demo intro.

nintendo#

For some reason, there are a couple of songs from Nintendo albums in this folder.

Epona 04.adp - Track 4, Lon Lon Ranch, from the Ocarina of Time Re-Arranged album.

Spmario.adp - Track 6, Super Mario Bros., from the Super Mario World jazz album.

Unused Bitmaps#

The images folder contains several bitmap images that don't seem to be used anywhere.

A small picture of...dogs? It's a little hard to tell. The texture was made to tile seamlessly, so it may have been used as a background image. The Wii Service Disc (found in the 2021 Gigaleak) contains a higher-quality version of this image alongside variants with inverted colors.

Colorless bricks.

The logo for ArtX, the original developers of the "Flipper" GPU created for the GameCube. They were acquired by ATI a little over a year before the console launched.

A crudely-drawn smiley face with stars and text saying "Dolphin", the original codename of the GameCube.

Stereoscopic 3D#

According to Nintendo, the GameCube was meant to support stereoscopic 3D output, but cost and lack of consumer interest led to the feature being shelved. However, the Service Disc still contains some remnants of this planned support in the form of stereoscopic test images.

A Kamov Ka-27.

A primitive Madcat from the BattleTech franchise.

The RX-78GP03S Gundam "Stamen" from Mobile Suit Gundam 0083: Stardust Memory.

Bizarrely, there are also a few images from Quake:

Unused Textures#

Textures for a car model can be found in gxDemos/CarTex.tpl. It has an associated .gpl model. Both this and MechaTex.tpl below are used in the smp-gxmodels demo that was included in the GameCube SDK.

Texture	Model

Textures for some kind of mecha found in gxDemos/MechaTex.tpl. It also has an associated .gpl model.

Texture	Model

gamecube.tpl has the background for the menu, but it also has textures for a GameCube (specifically the DOL-001 model, as indicated by the presence of the Digital AV port on the back):

Oddities#

A picture of good ol' Mario. A smaller version of this picture is used in the game's banner.

A picture of good ol'...inverted Mario, specifically an inverted version of the above image.

Both of these are used in one of the tests, but the origin of them is curious: they're a cropped version of this image of Mario leaning on the IBM logo; IBM made the Gekko microprocessor for the GameCube.
