Other than just playing your old NES games, the RetroN 1 HD — living up to the "HD" in its name" — actually upscales them to high-definition.

You might be wondering what "upscaling" means when we're talking about 8-bit games from 30 years ago. In the case of the RetroN 1 HD, it means you can play those games on your HD television in the correct aspect ratio (16:9) instead of having massive black bars on either side of the screen.

Because these games are so old, they are presented in a 4:3 aspect ratio — which is to say, "they weren't presented in a widescreen format." As a result, NES games can look unfortunately scrawny on a modern television. The RetroN 1 HD fixes that issue.

BONUS: There is a switch on the bottom of the RetroN 1 HD that enables you to switch between the classic aspect ratio (4:3) and the modern one (16:9), if you're into that kinda thing.
