It is possible to declare 2 screens and pick one in the layout view, but this doesn't accurately represent the hardware at all. I think 2 SVG screens just for inverting the colours is a too hacky solution. Maybe it's possible with shaders, HLSL anyone?
And how would you select the console to use that way? I think the main problem is the way these games are loaded since they don't consider the console at all, if there was an actual rzone driver you could load them as "mame rzone rzindy500" or "mame rzonesc rzindy500" and each having a different SVG wouldn't bother me much tbh. I understand why things are done the way they are though just stating it's simple to deal with cases like this where you have multiple consoles compatible with the same cart. This is how you'd deal with it for say stuff like Game Boy.

Do you know which games have those filters? I don't recall seeing any games for sale including them so was there some games sold in a different package which included the filters?
