Why is everyone calling this fake hardware? It's an FPGA solution. I would consider this system, with the fpga, to be at parity with the real hardware. I think of FPGA systems as if it was the same as the real system, but just add another manufacturer to builders of the console. So in the case of Genesis/MegaDrive there were a number of manufacturers back in the day (I think hitachi, samsung, TecToy, etc.) Now there is an additional manufacturer that makes genesis hardware; These Polymega guys.
For those saying why not just get a PC to emulate - a) Polymega is a FPGA solution. b) consider that not everyone has a PC in their living room, nor would they ever want one in there. I thought we knew this already?
Also, Polymega also plays SEGA/MEGA CD ROM, as well as Turbo/PC engine CD ROM, in addition to the NG-CDROM. As far as I know there are no other set-top FPGA solutions that play CD images. The only other way to play these on real hardware would be difficult, and not as nice as this (HDMI, menu, save-states, fast-load) as many of these old systems are broken, or will break. Polymega is a new solution with a fresh out-the-bag smell guys.
If they deliver I'm getting one for sure to play CD ROM systems.
