CUSTOM Rendering Resolution

[pillowedshirt]

Hello, I understand that custom rendering resolutions are not a feature in ppsspp, there is only auto and 1x-10x. But, I need to figure out a way to create a custom rendering resolution.

So, I want my rendering resolution to be 5760x1080. I understand that the game will look funky. I found the fov for a game and essentially I am trying to play the game in ultrawide format. But, no matter how much I alter the fov the game still appears stretched due to the rendering resolution.

I know this is a function in pcsx2 and I'm wondering if there is a way that I can create an ini or something of the sort that could create this custom rendering resolution I want. Is there any way this is possible?
