Thanks for pointing out that line. In the sliders, I see where you can change to a different effect...such as super-eagle or hlsl, but I don't see where you can change the aperture mask. Where is that slider?
Creating a copy or more of the crt-geom-deluxe.json in the Chains folder with different names is enough? I don't have to create copies of the corresponding files in the other folders such as Effects and Shaders?
