I am trying to write a small batch file or ps1 script to add a non-game shortcut to the Steam library. Unfortunately, I am unable to figure out where valve is saving the info. No luck in the registry.
This will be for Marvel Heroes 2015, launching the x64 executable. I have a bunch of brothers who it will be easier to just send them the batch.
