At just 75 grams the RG Nano is one of the smallest emulation handhelds on the market, and the smallest made by Anbernic – suitable for a keychain! It’s also among the weakest, though. Don’t expect to play more than the occasional Game Boy or SNES game here … and for not more than a few minutes at a time. The Nano also includes a digital clock display and an MP3 audio player.
