Has anyone heard of Pound technologies hdmi cables for retro systems?

I discovered these on a YouTube channel the other day. The Dreamcast cable interests me the most because it uses the DCs VGA mode to send the higher supported resolution as 720p to an hdtv. Obviously VGA isn't supported by all DC games, but the large majority do, and you can trick half the rest into VGA mode via a gameshark disc.

They also make hdmi cables for the original Xbox, PS2, SNES and Turbografx. Quite interested in the PS2 and SNES too, although I have my PS2 and xbox connected via component cables so it's not really needed, other than to declutter cables (as component is going though a switcher).

Has anyone had experience with these cables?

They also make a SNES clone that auto upscales to 720p via hdmi output, plus supports both ntsc and pal carts and controllers. Could be interesting to get around multi region issues. Will have to research it.
