WiiScript

WiiScript is an on-console Lua scripting environment for Nintendo Wii homebrew. It combines a built-in editor, Lua runtime, and SD-card persistence so scripts can be written, saved, and executed directly on the console.

Features

• Embedded Lua runtime
• On-console code editor
• Script loading and saving
• Wii input and graphics integration
• Homebrew Channel-ready boot.dol output

Build

Requirements

• CMake 3.20 or newer
• A configured Wii homebrew toolchain
• libogc and the libraries referenced by CMakeLists.txt
• GRRLIB and FreeType dependencies

cmake -S . -B build
cmake --build build

The build places boot.dol, meta.xml, fonts, and UI assets in bin/.

With wiiload configured, build and send the application to a console using:

cmake --build build --target WiiScript_run

Structure

• src/ — editor, runtime, storage, and Wii integration
• data/ — fonts, icons, and packaged UI assets
• external/lua/ — embedded Lua source

Status

WiiScript is actively developed homebrew software. Back up SD-card data before testing new storage behavior.
