Ive been really into SBS 3D since getting a Quest 2, and I’m wondering what kind of SBS options might apply to RetroArch. I feel like I remember a shader existing, and maybe a core or two having options.
I didn’t see a centralized place about SBS 3D though, so I thought I’d ask a general question about it here.
There is a “stereoscopic-3d” folder in the glsl and slang shaders. It works but isn’t as great as you might be hoping. I believe I tried it in concert with Virtual Desktop.
For a better experience I would suggest trying EmuVR.
It takes a bit of patience to set up, but uses Retroarch, so that part is familiar enough. It is a blast with a virtual 150" screen in lightgun mode.
