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.

Accessory Tests / Controller Test

  • Results in "SI:Unknown command (0x43)" error from Dolphin when the test starts. Resolved sometime before 5.0-10167
  • The Control Stick test is near impossible to pass without using a real GameCube controller and a Wii U Adapter due to diagonal ranges being over 75.

Refer issue 8351.

Hardware Status / Clock Speed

Initially registers speeds far lower than expected (i.e. 0MHz), rerunning the test registers speeds more in line with expectations. Fixed since at least 5.0-14095. The clock speed is still not the same as hardware. Refer issue 8353.

Hardware Test / Register Test

  • Fails on Test 3 showing: "gpits.dol Code:85400001".
  • Hangs on Test 9 siram0.dol. Fixed since at least 5.0-14095.

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.


The car demo and Optical Disc Drive Audio test results in a warning from Dolphin: "Interesting - Software triggered Decrementer exception" when it exits. Refer issue 8352. Fixed by 5.0-8064.

OpenAL Audio

Various audio sounds odd regardless if HLE or LLE audio is used with the OpenAL backend. Refer issue 8348 / issue 7955. Improved by 5.0-798, fixed by 5.0-3345
