 Note: There might be some distros (e.g. older Ubuntu releases) that launch python 2 instead of 3 when running `python`. In that case you'll need to replace `python` with `python3` in the launch option line.

 ## How it works
 
 When the game is launched through steam, the tool creates a patched version of `eldenring.exe` in a temporary subdirectory while leaving the original intact. As long the flag `--with-eac` is not set, the tool modifies the steam launch command to launch the patched executable instead of `start_protected_game.exe`, thefore ensuring that the patched exe is never run with EAC enabled. After the game is closed, the patched executable is removed.
