Hello fellas,

can anyone tell me where resolutiions savegame lives?

I couldnt find it in any of the classic locations. I looked in $HOME ~/.config, ~/.config/unity3d, ~/.local/share, and the game folder.

thanks for pointers :)

You've already looked in the right places, I'll look if I find it.
(I saw a little late that the question is old, you may have found the solution?)

_ For those who don't know:
1) Here is the most common place to find the backup files:
/home/YouUser/.local/share/Publishers/Game/ file.save
/home/YouUser/.config/Engines/Publishers/Game/ file.save

2) You can also search for the file, if you know its name, for FTL it is continue.sav
/home/YouUser/.local/share/FasterThanLight

for Galaxy Squad it is: saveData.txt
/home/YouUser/.config/unity3d/Oleg Kazakov/Galaxy Squad

Resolutiion is built with the godot engine, so you have to search in:
~/.local/share/godot/app_userdata/Resolutiion
