The first model of the NES wasn't all that great; just ask any one of the millions of six-year-olds who independently discovered blowing on a cartridge made it work. The second NES hardware revision, the top loader, was better but only had RF video output. These are the only two pieces of hardware that can play every single NES game, and even with years of hacking NES-on-a-chip devices, there's still much to be desired.
