[Feature Request]: Add "Backend Renderer" to custom config

[Tubuxis]

Is there an existing issue for this?

• I have searched the existing issues

What feature are you suggesting?

Add the ability to save the selected Backend Renderer to custom configs per game. At the moment, it is explicitly ignored and each game will default to the current global configuration for the Backend Renderer.

Why would this feature be useful?

There are some games which have graphical glitches (or simply will not run at all) on certain backend renderers. For example, on the Linux version of Vita3k running on my Steam Deck, Hatsune Miku: Project Diva X will have a pink filter over everything when being run on OpenGL which is not present on Vulkan. However, Persona 4 Dancing All Night will crash on the menu screen on Vulkan but not on OpenGL. Being able to have the custom config dictate which backend renderer is used for each game will add convenience.

Other emulators or software with a similar feature

I'm fairly certain the majority of emulators which support custom configs per game contain the backend renderer as a saved variable.

Platform (if relevant)

None

This is already implemented in the Android version. I guess it will be available on the PC version when the Android branch gets merged.
