Paul, please check the Snes interlaced signal issue with these vga adapters.

Use hdmi_limited=1 with these adapters if you see missing black steps with 240p test suite and Pluge pattern.

For some reason the ADV7513 does not use Full Range as default for RGB, and these VGA DACs read that "RGB Quantization range" flag and respect it.
I know this because the RetroTink2x has ADV7513 too and I helped Mike (creator) to tweak its HDMI output.

hdmi_limited ? 2'b01 : 2'b10

thanks for pics!
But i suggest to cross the sides in that recessed place near VGA connector because board edges i think touch the case and that wire on edge will make board position uneven.
