*just realised, I forgot to menton why a workaround is needed – it is because if there is more than one mod in the /Paks/ folder then a game selection screen appears which can only be controlled by keyboard. The method above gets around that screen appearing at all and launches directly into the game selected. :)
*Edit – I think I may know a slightly less dirty way of doing this, where only one binary would be needed in the parent folder, but can’t test this until later on after work! It’s dependent on whether Linux allows you to point a .sh script to another .sh file? (both containing shortcuts).
