Before we start, let's get one thing out of the way: there's no practical application for the apps demonstrated below, at least not in the way they're being used. You can't seriously play a game meant for a 20-button controller on a screen smaller than two inches across, even if your fingers are tiny enough to hit the virtual buttons. This is the work of an enthusiast gamer and Android fan. It doesn't have to make sense.
Alright, now that that's out of the way: YouTube user Hacking Jules would like you to see his collection of game emulators running on Android Wear. Sure, getting things like an NES or Game Boy emulator working on the Snapdragon 400 chipset that powers most of the watches isn't all that difficult, but how about something a little more intensive? How about something with full 3D graphics and a complex control scheme? How about Ocarina of Time?
That's classic 3D Mario and Zelda games running in a Nintendo 64 emulator on the original LG G-Watch. And not doing too badly, all things considered. It certainly isn't running at full speed, and you can't expect to beat the final boss with buttons a few millimeters across. But as a pure exercise in gaming excess, it's pretty cool to watch.
Want something even more insane? How about the recently-posted video of the PPSSPP emulator running on the same G-Watch, below. If you want to play games on Sony's original portable, you'll have to deal with even more intense graphics and a 16:9 aspect ratio, which means almost half of the screen on the square watch is full of black bars. Monster Hunter is taxing the poor SD400 so much that the character looks like he's walking in slow motion... if you can even see him as the operator uses the on-screen thumbstick.
Never change, Android gamers, never change. I know that somewhere out there, right now, there's someone who won't rest until he gets The Witcher 3 running on the Android Auto unit in his new Jetta.
