Service Disc
The GameCube Service Disc is used to perform diagnostic testing of a GameCube.
Emulation Information
Problems
Accessory Tests / Controller Test
- Results in "SI:Unknown command (0x43)" error from Dolphin when the test starts.
- Test fails and displays a "Failed" message post the directional control test.
- "Press the A Button to continue." text appears offset from the black box it presumably should be rendered inside. This can be resolved by using the real GamcCube fonts extracted from a GameCube BIOS.
Refer issue 8351.
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 issue 8348.
- The Optical Disc Drive test results in a warning from Dolphin: "Interesting - Software triggered Decrementer exception" when it exits. Refer issue 8352.
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 issue 8353.
Hardware Status / Register Test
- Fails on Test 3 showing: "gpits.dol Code:85400001".
- Hangs on Test 9 siram0.dol.
Refer issue 8354.
Hardware Status / CPU Test
Hangs on Test 6: l2c.dol. Refer issue 8355.
Hardware Status / Memory Test
Fails Test 1 showing: "memreg0.dol Code 9". Refer issue 8356.
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 issue 8357.
Hardware Status / Optical Disc Drive Test
Immediately fails Test 1:dipronto.dol with error from Dolphin: "DVDInterface tried to execute non-existing command". Refer issue 8358.
Demo
Audio in the demo sounds odd regardless if HLE or LLE audio is used unless using the XAudio2 backend. Refer issue 8348 / issue 7955.
