Any fix for Gal*Gun: Double Peace 21:9 3440x1440?

[Botan]

Hello all, I just wondering if anyone does know a fix for this unreal engine 3 powered game or have know some cheat engine 21:9 codes from other unreal engine 3 games. I might be insane madman for asking this.

So the resolutions in game are locked to 1920x1080 in-game but I can force to my choice of resolution
by using .Bindings=(Name="F4",Command="setres 3440x1440f") in DefaultInput.ini like any other normal unreal engine 3 game or Borderless Gaming

But the game rendered graphics are stuck in/pillarboxed to 16:9 aspect ratio similar to Tekken 7's one where "as you can see some 2D elements extend beyond the 16:9 ratio"

I have tried using the Cheat Engine Tables from Tekken 7 & Street Fighter V & the common hex codes from The Walking Dead: A New Frontier but unfortunately it does nothing to the game as expected.

I would appreciate a hand & maybe fixing a fix for this would work for other unreal engine 3 games. Like The Walking Dead: A New Frontier 21:9 CE method works for 007 Legends & Amazing Spider Man 1
