Modded dinput8.dll from FL HD Edition allowed to fix mouse in borderless fullscreen?

[Skyy]

Hi all I'm new here and playing with a friend who introduced me to Discovery. It's been a great experience so far but I'm wondering one thing. When I set the game to borderless fullscreen the mouse snaps back to the center whenever I touch the edge making Mouse Flight really annoying. I previously played Freelancer HD Edition in single-player and they had a modified dinput8.dll to stop this behavior.

Now I wonder if I would be allowed to use this .dll on Discovery too or if it would be seen as cheating.

Thanks for any info in advance!
