Nintendo GameCube

The Nintendo GameCube is a console developed by Nintendo. It was released in 2001.

Nintendo Gamecube is emulated through the Dolphin emulator, which is the same emulator we use for the Nintendo Wii. Its emulation performance are stunning, and it offers several options to enhance the graphic quality of the Gamecube titles, that can be upscaled and look gorgeous, even by today's standards, if your PC can support it.

Some of the options for enhanced visual quality are available from the “Advanced System Options”. In particular you can enable a higher VIDEO RESOLUTION that will upscale the 3D models to a higher resolution, in combination with the use of HIRES TEXTURES.

This system scrapes metadata for the “gc” group(s) and loads the gc set from the currently selected theme, if available.

  • Emulator: Dolphin
  • Accepted ROM formats: .gcm, .iso, .gcz, .ciso, .wbfs, .rvz, .elf, .dol, .m3u
  • Folder: /userdata/roms/gamecube

No Nintendo GameCube emulator in Batocera needs a BIOS file to run.

Place your Nintendo GameCube ROMs in /userdata/roms/gamecube.

If you have a Riivolution patch, first create its JSON file as outlined on the Dolphin emulator page.

For general information about the Dolphin Emulator itself, you can also visit the Dolphin Emulator page.

UBERSHADERS wii.ubershaders Improve performance with Ubershaders. Ubershaders take advantage of your GPU to avoid in-game stutters as it generates shaders for the first time; this can happen when a certain special effect shows on the screen or a new model is rendered. Hybrid ubershaders are preferred, it will use the GPU accelerated ubershader if available to avoid stutter, otherwise it will fall back to traditional shader generation. Exclusive ubershaders will only use ubershaders, only activate this option if you have an extremely powerful GPU. Normally there is no downside to activating ubershaders, however it does increase the minimum requirements out of your GPU to run. On especially weak hardware, such as SBCs, ubershaders are disabled by default. They can still be manually turned on, but you may encounter more stutter if on an SBC. Skip draw is a hack that opts to take a different approach altogether: don't display the object in game if its shader hasn't compiled yet. Obviously, this can result in visual glitches, but may be the best option performance-wise if your hardware is extremely weak.; asynchronous is preferred, synchronous is more compatible.
⇒ No Ubershaders no_ubershader, Exclusive Ubershaders exclusive_ubershader, Hybrid Ubershaders hybrid_ubershader, Skip Drawing skip_draw.
PRE-CACHE SHADERS gamecube.wait_for_shaders Compile shaders on next launch of game (one time). Reduces micro-freezes.

RetroArch has its own page.

libretro: dolphin

There's nothing here to configure. Use RetroArch's Quick Menu for now.

Here are the default Nintendo GameCube's controls shown on a Batocera Retropad:

In a similar fashion to using Bluetooth passthrough for Wii controllers, you can use USB passthrough to allow Dolphin to entirely handle the GameCube controllers from your adapter.

Download the following file:

SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ATTRS{idVendor}=="057e", ATTRS{idProduct}=="0337", MODE="0666"

Save it as a udev rule to userdata/system/udev/rules.d/51-gcadapter.rules (there is no need to “reload” the udev rules, if you want to be sure just reboot Batocera).

You must activate “Custom Pad Profile” and select “GameCube Adapter for Wii U” in Dolphin's controller settings. Boot up Dolphin, attach the Adapter, and it should become selectable.

You can access Dolphin's menu in-game with [Alt] + [Tab] to do this.

Since v31, it's possible to create and save custom pad profiles for GameCube (Dolphin emulator)

All you need to do is to go to pads options on Dolphin emulator by pressing the F1 key from system menu on EmulationStation.

Here, you can customize and save buttons mapping, and stick calibration.

Only one profile per pad.

After that, you simply need to set the USE PAD PROFILES option (in Dolphin advanced options on EmulationStation) to TRUE and your custom profile will be loaded.

Pad profiles are saved in /userdata/system/configs/dolphin-emu/Profiles.

For more information on remapping per system, refer to the relevant section on the remapping controls per emulator page.

Your GPU might not be strong enough to calculate the caches in real-time while playing. This can be worked around by activating the PRE-CACHE SHADERS gamecube.wait_for_shaders setting, at the cost of having to wait a while on your next launch of the game (one time only).

It's still happening!

For exceptionally weak hardware, it might also be worth turning off UBERSHADERS gamecube.ubershaders altogether.

Dolphin has a great and informative wiki, usually detailing which settings may need to be altered to avoid issues in certain games. Search for your game on it here:

For further troubleshooting, refer to the generic support pages.
