About This File
The patcher removes black bars at all resolutions, although it does not address the UI cropping issues present in the game at 21:9 and wider, making it likely inapplicable to 32:9.
The in-game notes can be read without closely inspecting them to work around the issue.
Simply unpack the archive and follow the instructions to patch the specified game file.
Thanks to Dopefish for playing through the game to test the solution at 2560x1080.
