I'm getting it because I'm dying to see how well engineered a Famiclone can be. Nintendo doesn't make substandard stuff like Neo Geo X (which, for all the hate, is by far the nicest system of its kind that I've ever used) or the 35 different mini Genesis systems with garbage controllers and the same 8 games in them. I'd expect the pad to be extremely authentic.
As for emulation...seriously, you probably can't even get Energy Star complied with an actual NES and if you don't tell people they'll never know. Fancy FPGA type stuff isn't much different than software emulation in the grand scheme of things assuming the power is there. I expect the emulation will be very good. While I rarely buy NES ROMs I've had zero problem with the emulation quality of other systems on Virtual Console. I have Super Mario Bros for Wii U and I've never noticed garbled sound or any other problems really. I'm not saying it doesn't occur, just that I've never noticed it. My NES fandom is very casual.
Btw, what a nice game list.
Also, I have the TvC Wii stick and it looks like it will work with this, maybe, so that will be the nicest NES controller I've ever used.
