I think you can get them for $5 each on the Nintendo store.
I have a Wii and a Wii U hooked up to a 65" screen. And no open HDMI inputs.
It does look cool. I can't imagine how one emulator could make them look better than any other. They are low resolution games. They should look like crap, like they always have.just the look of it is probably worth the $60 to me. but the big question is will they use the same emulation tech with this that they use for NES games on the wii and wii u. on the 3ds they look fine with that small, low res screen, but on a home television the wii and wii u versions of nes games look very compressed. there are plenty of somewhat illegal, free emulators that look WAY better and i hope this mini nes uses something more like them.
