Steam Deck [linux] FOSE Installation Modding

By SeeFooBoo

Hey all, I'm going to keep this short. After hours of researching how to install FOSE on Steam Deck and not finding a guide or something that worked (I'm familiar with linux, but not an expert), I came up with a solution and got Fallout Script Extender (FOSE) working on my Steam Deck.

There's probably a more efficient way. Also, a keyboard and mouse helped. Since there are numerous tutorials online for steps 0-6, I'm not going to go into detail.

i have followed all your directions above and all I get is error after error. love my steam deck but will have to just install on Windows, much easier.

You can actually just follow the regular instructions but when you execute the patcher use the Fallout 3 protontricks as the environment. You can just put all the files in the game's directory.

Steps 9 through 12 (plus step 15) are needlessly overcomplicated. You don't need Bottles for this.

Install regular Wine from Discover store and use "flatpak run org.winehq.Wine Patcher.exe" in a terminal to run the patcher. Done, no messing around with Bottles or dependencies.

You can run the patcher straight from the game's common directory, there is no reason to copy game files back and forth to different places.

Also you skipped number 13. The list goes straight from 12 to 14.
