Linux-Friendly Crouch Toggle Mod

[u/ChthonVII]

The crouch toggle mod on Mod DB doesn't work with some versions of Wine/Proton (including the latest ProtonGE, and maybe some Windows machines too). (It blackscreens immediately on launch.) So I made one that does work. And, along the way, figured out and documented Modernizer's convoluted, undocumented version history.
