[NixOS]: How to Fix BSA Decompressor's BASS Init Error

It happens because it seems like BSA Decompressor depends on the libasound2 library. And since we're using NixOS, it doesn't find it, because of the way Nix works, blah, blah, blah...

Really simple, actually, we just need to add the executable file of BSA Decompressor to Steam, as a Non-Steam Game. And... magic! It should work now!
Thanks to Steam Runtime, which has the library we need.

If BSA tells you something like "Uh, dude, you don't have any space left in your disk"
Open Protontricks, choose the BSA Prefix and run winecfg.
Add a new drive, "most likely D: by default" and make it point to /home
Check show dot files too if necessary, because now you will run BSA again, and find your New Vegas Installation.
Now it should decompress with no problems.
