Launching the Justine DLC outside of the default launcher

[loocash]

Hello!
I've installed the GOG version of the ATDD on Linux Manjaro. The game runs correctly but the launcher does not start. I wonder If there is some other way to launch the Justine DLC outside of the default launcher. Some file, command or anything.

You can launch it by adding "ptest" as an command line argument
So like:
Amnesia.bin.x86_64 ptest

That was it, big thanks.
