# Builds the per-platform installer/setup tool (WiiCompiled-Setup.exe /
# WiiCompiled-Setup-x86_64.AppImage) via Launcher/Build-Installer.ps1 and
# Launcher/build-appimage.sh respectively - the same scripts a maintainer runs by hand today to
# produce a GitHub Release asset. This does NOT build the actual translated game executable:
# that step requires the end user's own Mario Kart Wii dump (Assets/main.dol, Assets/StaticR.rel),
# which is proprietary and not present in this repository or in CI.
