If you've been floating around the interwebs in the last week or so, there's a good chance the name GBA4iOS has crossed your vision more than once. A Gameboy Advance emulator for the iPhone and iPad, works flawlessly. Better yet, it's an easy install that doesn't require jailbreaking, and it has a direct pipeline to a ROM store built right into it. For fans of emulation, it's a pocket dream come true.

Emulation, of course, is a touchy subject. The legality around it scream "grey market" at best. But regardless of your feelings on the subject, you have to admit that GBA4iOS is a technical marvel - especially when compared to all of the mediocre GBA emulators that have tried to sneak onto your iOS devices in recent years. And it's install method - requiring nothing more than visiting a website and changing the date on your phone - is a wonder in and of itself.
