Here's the situation. I own the game. (Not just the free version, I own the base paid game + Season Pass) but everything outside the Season pass is individual so I ain't paying for that (Especially since I have it all on the PS4 version anyways) The only DLC unlocker that works on Windows is copying the following set of files in the game's folder.

cdxclient64.dll

CoopLand.ini

CoopLand64.dll

dlllist.txt

steam_emu.ini

winmm.dll

This has been the method the game's very small community uses. I tried different DLC unlockers to no success (Even on Windows). This, however, doesn't work on the Steam Deck. Is there any command line I should add? overrides or something of the sort to make them work? Any help would be appreciated. This is the last thing I need up and running on my Deck for it to have everything I want on it.
