The GameCube Service Disc is used to perform diagnostic testing of a GameCube.
Emulation Information
Improper GameCube Font
Due to copyright concerns, Dolphin is unable to include official GameCube fonts, and instead uses Droid Sans. Unfortunately, Droid Sans does not align well with the size/kerning of the official GameCube font, which can cause text to be misplaced, dialogs to display improperly, and other issues due to differing text sizes.
This can be corrected by including a region appropriate GameCube IPL (i.e. BIOS ROM) under <Dolphin User Folder>/GC/. A GameCube "IPL.bin" can be acquired from a real GameCube using Swiss. Refer issue 8362. GameCube BIOS files need to be named "IPL.bin" in order for Dolphin to detect them, and should be 2,097,152 bytes in size. IPL files are different for PAL consoles and NTSC consoles, but American NTSC consoles use the same IPL files as Japanese NTSC consoles. The known good CRC32 checksums below can be used to validate files, but it is possible that a bad dump with a different checksum also works.
NTSC CRC32 | Brazil CRC32 | PAL CRC32 | |
---|---|---|---|
v1.0 | 6DAC1F2A | 4F319F43 | |
v1.1 | D5E6FEEA | 667D0B64 | |
v1.2 | 86573808 | AD1B7F16 |
Problems
Accessory Tests / Controller Test
- Results in "SI:Unknown command (0x43)" error from Dolphin when the test starts.
- The Control Stick test is near impossible to pass without using a real GameCube controller with the Wii U Adapter due to diagonal ranges being over 75.
- "Press the A Button to continue." text appears offset from the black box it should be rendered inside. This can be resolved by using the real GameCube 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 Audio 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 Test / Register Test
- Fails on Test 3 showing: "gpits.dol Code:85400001".
- Hangs on Test 9 siram0.dol.
Refer issue 8354.
Hardware Test / CPU Test
Hangs on Test 6: l2c.dol, due to Dolphin not emulating caches. Refer issue 8355.
Hardware Test / Memory Test
Fails Test 1 showing: "memreg0.dol Code 9". Refer issue 8356.
Hardware Test / DSP Test
Fails the first four tests, passes the fifth test and hangs in Test 6: bistram1.dol. If using HLE, Dolphin throws warnings on various unknown ucode's. Refer issue 8357.
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.
Configuration
Only configuration options for the best compatibility where they deviate from defaults are listed.
Audio
Config | Setting | Notes |
---|---|---|
Audio Backend | XAudio2 | OpenAL backend results in various audio issues. |
