As Dusk Falls ultrawide and wider fix

This interactive cinema type game published by Xbox Game Studios was released about two days ago and then someone on the WSGF Discord reported that it did not support ultrawide.

My plan for this week was to look into Stray and I even purchased it in the event it had any issues, but they were minor and easily fixed by the UE4 unlocker, so I asked for a refund and moved on. This was an opportunity to fix something new, even though As Dusk Falls flew under the radar of the community (very reasonably) invested in Stray.

Although a Unity game, its code was packed, and none of my old findings were immediately applicable. It was a tedious task of pure disassembling and experimenting again.

I managed to fix the apparent issue of pillarboxing and then of the UI, caused by removing the pillarboxing, though the mouse/controller pointer remained constrained to the 16:9 space. The buttons I could find were still accessible at 21:9 but not at anything wider. As such, I'm asking for volunteers to help test the game at 21:9 and I'm also sharing the fix with you. If all goes well and I release the fix to the general public, I may update this post with more screenshots and corrections.

Have fun and thanks for your continued support!

Update (July 22):
Yesterday I sent version 0.1 to three people, including Lyall, to help me test it. Lyall then told me that the cursor constraint issue can be fixed by manipulating an aspect ratio value. I had already experimented with those but not checked to see if it affected the pointer. Having the new knowledge and thanks to Lyall, I dug into it again and made it into a universal solution for any resolution.

Update 2:
I removed version 0.1 from the attachments here to prevent any confusion and keep the latest to the GitHub page linked above (version 1.1 at the moment).
