The original Tomb Raider files should go in this rom folder from your previous Windows installation.
You can safetly remove .exe & .dll files which are not necessary for TR1X to run the game.
We highly recommend your folders are in lowercase to ensure call files are accounted for.
Then create a launcher file with a .croft extension i.e. Tomb Raider.croft
This will allow EmulationStation (ES) to launch the game etc.
On first launch (provided you have internet) we will download the music files so don't be alarmed if slow. Subsequent launches will be faster.
To choose the Unfinished expansion pack, enable the associated ES option.
We will download the `Unfinished Expansion pack` if necessary so again the first launch may be slow.
/userdata/roms/traider1.croft
Place your Tomb Raider ROMs in /userdata/roms/traider1.
