Service Disc

The GameCube Service Disc is used to perform diagnostic testing of a GameCube.

Poorly Rendered Text
Small black blips appear around most text. Refer.

Accessory Tests / Controller Test

 * Results in "SI:Unknown command (0x43)" error from Dolphin when the test starts.
 * Results in "Failed" message post the test, "Press the A Button to continue." text appears offset from the black box it presumably should be rendered inside.

Refer.

Audio Tests

 * If using the OpenAL audio backend test audio is only heard well after the test exits, and plays much faster than it should, so the words "Left Channel", "Right Channel", etc are difficult to distinguish and sound more like static. These issues can be resolved if using the XAudio2 backend, though that's not available outside of Windows. Refer.


 * The Optical Disc Drive test results in a warning from Dolphin: "Interesting - Software triggered Decrementer exception" when it exits. Refer.

Hardware Status / Clock Speed
Initially registers speeds far lower than expected (i.e. 0MHz), rerunning the test registers speeds more in line with expectations. Refer.

Hardware Status / Register Test

 * Fails on Test 3 showing: "gpits.dol Code:85400001".


 * Hangs on Test 9 siram0.dol.

Refer.

Hardware Status / CPU Test
Hangs on Test 6: l2c.dol. Refer.

Hardware Status / Memory Test
Fails Test 1 showing: "memreg0.dol Code 9". Refer.

Hardware Status / DSP Test
Immediately fails Test 1: accprinter.dol with error message from Dolphin "HLE system tried to call an undefined HLE function 39320", regardless if HLE or LLE audio is used and then crashes Dolphin. Refer.

Hardware Status / Optical Disc Drive Test
Immediately fails Test 1:dipronto.dol with error from Dolphin: "DVDInterface tried to execute non-existing command". Refer.

Demo

 * Audio in the demo sounds odd regardless if HLE or LLE audio is used unless using the XAudio2 backend. Refer.
 * Pressing the B button displays odd black boxes over top of the demo, unclear what should be displayed. Refer.
