@mediamogul is the only 3D option a Red/Blue, or is there an option for side by side (my TV can create 3D from a side by side)?
I'm not fully up to trot on "Shaders" but while browsing around, there was some mention that somehow, I may be able to smash the shader and Retropie bits together and get a side by side 3D?
Ultimate goal: Raspberry Pi 3 B outputs 3D signal over HDMI, OR a side by side 3D image with the TV converting to a 3D image.
Or it could be impossible, I'm not sure.
