Midnight Club: Los Angeles - Complete Edition (USA) - native launcher.
What you get: the recompiled game (30,205 PowerPC functions rebuilt as native x86-64), a native Vulkan renderer and native audio, in a small launcher. No game data is included - you point it at your own copy.
Source: your own copy of the USA disc (title 545407F8) - a .iso of the disc, an archive of its files, or the extracted folder. The importer also installs DLC packs.
Run it:
# Linux
tar --zstd -xf midnightclubla-launcher-linux-x86_64.tar.zst
cd midnightclubla && tools/port_gui.sh # or ./run.sh
# Windows: unzip the windows launcher and run Launcher.bat
Needs a Vulkan GPU driver. CONVERSION.md inside the bundle has the details.
