Currently the following command line interface options are available:
-g, --gold (legacy: -gold)
Runs the Unfinished Business or the Golden Mask expansion pack, depending
on the game.
--demo-pc (legacy: -demo_pc) (TR1X only)
Runs the PC demo level.
-l <path>, --level <path>
Runs the game immediately launching it into the specified level. The path
should be absolute. Internally, this option uses TR*X_gameflow_level.json5
as a template instructing it how to run the game.
-s <num>, --save <num>:
Runs the game immediately loading a specific save slot. The first save starts
at num=1. This option can be combined with -l/--level.
