Through RetroArch, use the Lutro core to load the game's source directory:

retroarch -L libretro_lutro.so path/to/gamedir/

Alternatively, you can load a compressed .lutro file:

retroarch -L libretro_lutro.so game.lutro

Compile Lutro by installing the RetroArch dependencies, and running:

make

There are a few optional defines you can use to change how Lutro behaves.

• make WANT_COMPOSITION=1 Enables alpha-blending.
• make WANT_TRANSFORM=1 Enables scaling
• make TRACE_ALLOCATION=1 Enables memory allocation tracing

Run the Lutro testing suite by executing:

make test

To run tests manually, run:

retroarch -L path/to/lutro_libretro.so test
