GBA4iOS was a Game Boy Advance emulator for iOS that allowed you to play GBA games on your iPhone, even without Jailbreak. With the launch of iOS 7, the emulator has been redesigned to version 2.0 with new features and improves usability. The countdown clock featured on the official GBA4iOS website has now reached 0 and anyone can download the new app.
After a long beta, GBA4iOS overhaul includes Dropbox support, support for MFi Game Controllers, cheat codes, a collection of controller skins for Game Boy Advance and Game Boy Color games, a built-in web browser for downloading games and many other features. The emulator doesn’t require Jailbreak to work since it takes advantage of Apple’s Enterprise Distribution Program , which allows some non-AppStore apps to be installed without a jailbreak.
