You are looking to this post, where we will provide you with an ultimate solution for fixing the 21:9 resolution in FATAL FRAME / PROJECT ZERO: Mask of the Lunar Eclipse.
In order to achieve this, you will need to unpack the game’s executable file with Steamless, which can be easily found by searching on Google and redirecting you to Atom0s’ GitHub page. Once you have found the page, then rename the new executable file, removing the “.unpacked.exe” so it appears like the original file.
Press Ctrl+R and change the text string to hexadecimal values. Change the search direction to “all” and search for “39 8E E3 3F”.
- 2560×1080 = 26 B4 17 40
- 3440×1440 = 8E E3 18 40
- 3840×1440 = AB AA 2A 40
- 3840×1600 = 9A 99 19 40
- 3840×1620 = 26 B4 17 40
- 5120×1440 = 39 8E 63 40
- 5120×2160 = 26 B4 17 40
- 6880×2880 = 8E E3 18 40
After making these changes, simply hit “replace all“, save the file, and install ReShade. When installing ReShade, ensure that you select the “fubax-shaders” and make sure the “aspectratio.fx” is ticked. In ReShade, ensure that the “aspectratio.fx” is checked and adjust the slider of the correct proportions to “0.343” for 21:9.
We hope that you have found this guide helpful, and we would like to extend our gratitude to Overkill Labs on Reddit for providing this method for MOBW. Thank you for reading!
