A wrapper launcher for Kerbal Space Program steam installs to bypass Take Twos KSP2 oriented launcher. Fully passes steam command lines and properly sets up the working path, source code is here for all to view. Releases are here:
https://github.com/R-T-B/KSSL/releases
To install, simply extract a release zip into your [KSP Install folder]/PDLauncher. KSP2 release zips are for KSP2 only. The others are for KSP1.
This is a .net core 3.1 app and will prompt you to install that if not present. May work crossplatform if you can install it too, no idea, I only tested on windows.
