An intelligently designed emulator allows viewers to input text commands like A, B, Start, and Select, which in turn control what happens in Pokemon Red/Blue. The video has been live for nearly 48 hours and viewers have, miraculously, already beaten the first gym and have a level 23 Pidgeotto.
There are currently more than 7,000 viewers on "Twitch Plays Pokemon," and the chat is ablaze with commands. It's a wonder to see in action, and simply proves that there are even more ways to enjoy 15-year-old video games.
