About

WiiCompiled is a native PC port of Mario Kart Wii made with static recompilation, with no emulator, interpreter or JIT at runtime. The README says it is not yet finished: the game should be playable, but compatibility, rendering, networking and performance are still being worked on.

How it differs from the original

It adds an unlocked framerate with experimental interpolation, any window aspect ratio, high internal resolution, music ducking when other audio plays, and an F10 settings bar. It also supports Dolphin-style input expressions, real Wii Remotes over Bluetooth and Retro Rewind as its own build profile. The README states physics match the original, as shown by in-game ghosts.

Getting started

You need your own clean, unmodified PAL RMCP01 disc image (ISO, GCM, GCZ, CISO, WBFS, WIA or RVZ); no game files are provided and other regions or patched executables are rejected. The easiest route is the Wheel Wizard mod manager, which downloads the setup tool and walks you through install. On macOS, install the setup package from the Releases page, choose your disc image, and it translates and compiles the app locally. Setup takes a while because the translated binary is not shipped.

Known issues & limitations

Compatibility, rendering, networking, and performance are still being worked on.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game (Wii version).

You need your own legally dumped, clean, unmodified PAL RMCP01 disc image; ISO, GCM, GCZ, CISO, WBFS, WIA, and RVZ formats are accepted.
Installation needs about 20 GB of free disk space; the final game size is about 5 GB.

Features

Interpolated frames can make play look smoother on 120/144 Hz monitors; interpolation is experimental and may show artifacts.
The camera adjusts live when you resize the window, allowing any aspect ratio.
You can play at several times the console's resolution.
The official Wii U / Switch GameCube adapter (WUP-028) is supported.
Retro Rewind can be installed as its own profile.

How to install

With Wheel Wizard, select your clean PAL RMCP01 image in Settings, enable WiiCompiled (beta), then install from the Home page.
On macOS, download and open WiiCompiled-Setup.pkg from the Releases page, then choose your clean PAL RMCP01 image and select the base game or Retro Rewind.
For Retro Rewind, choose the RetroRewind6 folder or its parent folder.
