I recently downloaded one ISO in 3D: Tsubomi - 3D virtual masturbation navigator[DDT-349]
And I was thinking of also ripping the 3D part(it's also side-by-side though), but I don't have a 3D TV and wanted to do some test to see what I can and cannot do. For example, can I crop the black bars on each side without affecting the resulting picture?
I made a post asking for volunteers to test it, but haven't got any replies yet:

Maybe most rippers are like me and don't have the hardware required to play them so they don't bother with it.
