Mario Kart Wii with 200+ tracks and 60+ characters, with free online play.

First download your prerequisites
Wiicompiled installer
https://github.com/patchzyy/Wiicompiled/releases/download/v0.2.31/WiiCompiled-Setup-x86_64.AppImage

Retro rewind patch is here - extra tracks & online functions.
https://update.rwfc.net/RetroRewind/zip/RetroRewind.zip

And a ROM - original MKWii ROM
https://archive.org/download/mario-kart-wii-pal/RMCP01.wbfs

Once you have all these run this command:
```
./WiiCompiled-Setup-x86_64.AppImage --game "path to ROM" install --profile base --retro-dir "patch folder" --download-retro-wfc-payload
```
Note: The patch folder is the one named RetroRewind6 once you unzip it's source file.

This command will take a while, and when it's done you'll have a shortcut in your menu.
