Important warnings:

  1. Dolphin is not officially supported, and has not been tested extensively.
  2. Dolphin is not race legal.

Dolphin is a popular emulator for both Gamecube and Wii. As it can be used as a Wii emulator, you can load a WAD into it and play the randomizer that way, meaning you will be emulating a Wii which is emulating a Nintendo 64. Yes, it sounds convoluted, but it's not terribly complicated to set up and brings the benefits of both playing on emulator (faster in certain places, improved visuals) and playing on Wii VC (faster in other places, more accurate emulation). That being said, playing the randomizer on Dolphin is still largely experimental, and this page will be updated as more issues and fixes for those issues are found.


While Dolphin will be used as a Wii emulator, it is actually much simpler than setting up a Wii. There is no need to soft mod, move data onto an SD card, or install a WAD. That being said, there are some steps that need to be taken first.

First Time Dolphin User Set Up

Download the latest beta release of Dolphin. Like other emulators, you will need the latest beta release of Dolphin rather than the latest stable release. Note that, by default, Dolphin will check for a new beta release monthly and auto-update.

Once Dolphin is downloaded, extract the zip and open Dolphin.exe. You should see something like this (except that, if this is your first time, your games list will be empty):

Note the buttons within the red box, these will be used in the upcoming steps. The first thing you will want to do is create a game directory. Go to ConfigPathsAdd... and select the directory in which you would like your games to be placed. You can even have multiple game directories, if you wish. This will then cause any .iso or .wad files in your selected directory to show up in the home menu, as seen above.

Click on Controllers on the home page. Controllers can be setup either as "GameCube Controllers", or as "Wii Remotes". For the purpose of the randomizer your controller will need to be configured as a "GameCube Controller" (even if it is, say, an Xbox controller). Under Gamecube controllers, click Configure next to Port 1.

If you are using a Gamecube Controller with a Wii U Adapter by either Nintendo or Mayflash (Wii U mode), then your controller should be detected and configured automatically and the new window that opens will simply ask you to enable/disable the Rumble Pak.

For reference, these are the default controller mappings Dolphin will use. Keep in mind that if you've used the webpatcher, or gzinjectgui with the right configuration, that D-pad left/right/down will be overwritten to properly work with boots/ocarina on D-pad.

If you are using any other controller, or if you're using a Gamecube adapter that is not recognized by Dolphin, then you will need to configure the controller yourself. Note that, even if you have a controller with analog triggers, you must set L and R for the buttons to work properly, not just L-Analog and R-Analog. Below shows a sample controller config with an Xbox controller.

Randomizer Dolphin Set Up

So, now you have either just finished setting up Dolphin for the first time, or are an experienced Dolphin user. There are a few more settings that must be set to certain values to properly play the randomizer.


First, under ConfigGeneral make sure that Allow Mismatched Region Settings is unchecked and Fallback Region is set to NTSC-J.

Next, under GraphicsHacks, ensure that Store EFB Copies to Texture Only is unchecked.

Starting a Seed

This is the only part of setting up Dolphin which is similar to the set up for Wii VC. Refer to the "Generating a Seed" section on the Wii VC page for how to generate a WAD.

After generating the WAD, place it in your game directory. It should appear in your home menu. Double-clicking the seed should then launch it the same way any other .iso is launched from Dolphin, no NAND installation or Wii channel required.

After Finishing a Seed

Since all OoTR WADs use the same internal ID, Dolphin will consider them all the same game, meaning saves will carry over between seeds. You'll just need to delete the old save data to make room for a new save.

Optional Settings

Depending on the power of your computer, you may want to enable some graphics enhancements. If your computer can handle it as it makes games look much nicer. Back on the home page, go to GraphicsEnhancements. There is no exact guide for what to do here, mouse over each individual component to see what it does. If your computer is powerful enough, you can probably enable most things without worrying about it. Otherwise, you may have to do some trial and error to figure out what your computer can handle. Per-Pixel Lighting and Anti-Aliasing above 4x are particularly demanding. Post-Processing Effects are mostly gimmicks.

Troubleshooting

These are common issues with running Dolphin. If you are having issues, try any of these that seem like they may help. If you continue to have problems running the randomizer in Dolphin, come to #setup-support on the Discord.

The Video is Stretched to 16:9

Go to GraphicsGeneralAspect Ratio, and select Force 4:3.

The Game is Running Slowly/Less than 20 FPS

The first thing you need to do in this case is look to the top left of your emulation window. There it should display both FPS and VPS. FPS is the framerate of the game you're running, while VPS is the framerate of Dolphin's output. Based on the VPS value, continue to one of the following subsections.

VPS is less than 60 and unstable

If this is the case, your computer can not handle the current emulation, you should turn down some of your graphical enhancements.

VPS is stable at 50

There is likely some issue with the region being stuck at PAL, ensure you took the proper steps regarding the region in Randomizer Dolphin Set Up.

VPS is stable at 60

This one is much trickier, as this implies that, as far as the emulator is concerned, the game is running at full frame rate. The current workaround for this is to go to ConfigAdvancedClock Override, checking Enable Emulated CPU Clock Override, and setting the slider to 200% (or whatever number seems to work for you). Note this is not a permanent solution and currently considered a workaround.
