Which games does the 8-Bitty support? Midway Arcade and Atari Greatest Hits, quirky little games like Forget-Me-Not and Super Crate Box, and dozens more. The list isn’t easy to track down, and the 8-Bitty doesn’t work with all the games the iCade does, but most of them translate well enough. On the Android side of things, the emulator app MAME4droid supports 8-Bitty. Ion’s list of iCade-compatible games gives you a mostly complete sense of the gaming library you can take advantage of.
There are drawbacks, though: the 8-Bitty works by tricking your iOS device into thinking it’s a keyboard, but simple button-mappings get laid onto games in ways that sometimes seem random.

Sometimes the shoulder buttons and other buttons do the same thing. Sometimes you have to press up on the D-pad to jump, instead of being able to press one of the four comfy red buttons like you’d want to. Most games have no control-tweaking options for the 8-Bitty, so you’re stuck.

You can even you use it with your iPhone, though I'm not sure why you would: it's larger than the ., once you're paired you can't use the
The 8-Bitty is a cute stocking-stuffer, a clever novelty gift, and, depending on your usage, a functional retro-gaming accessory for your iPad, iPhone, or iPod Touch. It’s less expensive than an iCade, and more flexible.
This isn't the perfect iOS game controller. It's an awkward, feisty little gadget that won me over with charm, not usefulness. It might do the same to you, if you keep your expectations low.
