Borti has posted updates to his N64 flex cable design. This will allow for easier installation of dual UltraHDMI and N64RGB boards, as well as help improve ground loop interference:
I installed today my #N64RGBv2 kit alongside of the #UltraHDMI unsing a FPC adapter to have resistors at the RCP-NUS outputs. Tests were running with extra long installation wires to proof the concept; everything works like a charm 😀 pic.twitter.com/NlQ2KE1USL

The effect of placing resistors @ digital outputs of the RCP-NUS for the #N64RGB installation wires. It reduces signal crosstalk, reduces reflection of the digital signals, removes over- and undershoots and should also help to reduce GND-loop noise. pic.twitter.com/0n7yPlHPhi
