I got a small break from work and swapped the HDMI cable with the one from my PS4 Pro and it seems to have cleared it up (~5min of testing). I think Analogue's cable must be bunk. Kind of a bummer since it's so pretty but it's only a HDMI cable. I'm sure I have extras around.
It would be awesome if they gave the SuperNT the ability to play NES and released a converter cart. I'd also throw in Gameboy/Super Gameboy but we may get that with the SD2SNES soon anyhow. Being able to play NES would make the SuperNT an insta-buy for me and several others. The NT Mini was just a tad too expensive for my taste and thus I am still rocking NES on composite through the Framemeister.
In short, it'd be awesome to have a Sega 16-bit and before console and a Nintendo 16-bit and before console. I don't expect it though and neither should anyone else. Analogue never sold that to us at all or even hinted at it.
