Here's a mod that I was working on for Fairy Fencer F: Refrain Chord that adds a few quality of life improvements to the PC release of the game.

Features:
* Unlocked Framerate and VSync support (Up to your display's refresh rate), including quick adjustments to FixedUpdate induced stuttering.
* Custom Resolutions and Basic Ultrawide support (Working on fixing some UI related issues with ultrawide resolutions however, that will be coming in a future update, due to the complexities of hooking certain private functions).
* Support for the game's built-in DualShock 4 (PS4), DualSense (PlayStation 5), and Nintendo Switch controller prompts.

Install Instructions: Extract the contents of "RefrainChordTweaks.zip" into the game directory. Go into BepInEx/Config/RefrainChordTweaks.cfg and adjust config variables as needed (This is where you need to go to switch the controller prompts or to force the game to use a custom display resolution). The display output mode (Borderless/Windowed/Fullscreen) can be switched in-game.

NOTE FOR STEAM DECK and PROTON USERS: You may have to use "WINEDLLOVERRIDES="winhttp=n,b" %command%" in your launch parameters prior to playing. Also, just in case, use ProtonTricks (can be downloaded from Flathub or the Discover app on Steam Deck) to install the .NET 6 Desktop Runtimes in case the game crashes. That can be found here: https://dotnet.microsoft.com/en-us/download/dotnet/thank-you/runtime-desktop-6.0.16-windows-x64-installer

Hotfix 1 Release Notes:
* Fixed a problem that was preventing UnityExplorer from hooking to the game
* Fixed Vert- FOV scaling during battles. Should be using Overscan scaling (So Vert- behavior with resolutions narrower than 16:9, and Hor+ behavior with resolutions wider than 16:9)
