Deadly Premonition ultrawide fix
Added 2021-10-12 09:04:24 +0000 UTCFollowing a request from a supporter, I first suggested following the PCGW instruction of using DPfix, which unfortunately resulted in stretching. Apparently, the issue was also reported on WSGF back in 2018.
It turns out that even with DPfix, the game still reads its internal resolution of 1280x720, using it for various calculations.
I found that replacing the float values with the desired resolution values in DP.exe addresses the problem. Sadly, the game does not appear to store the current display width and height anywhere near those, nor does anything write the aspect ratio value in real time, which would be useful for a universal and automated solution.
As of right now, you can search for 3F 00 00 A0 44 and replace the last 4 bytes with your width as a float and then do the same for 00 00 34 44 and the height.
To make applying this easier, I also created patchers for 2560x1080 and 3440x1440 and similar resolutions depending on the aspect ratio. I suspect that there would be some UI stretching at 32:9, making a packaged solution I could get behind problematic until further testing.
