GBA4iOS

Overall Opinion: The GBA4iOS emulator lets you play any GameBoy Advance, GameBoy or GameBoy Color game on your iOS-powered smartphone or tablet. You simply download the ROM from a website of your choice, load it into GBA4iOS, and off you go! It is that simple to install games. Downloading and applying skins was easy as well. There are many pre-configured options available for you to download, and you can create your own skins as well if you can't find one that suits you. With Dropbox sync, you can easily back up saves from one or more games to your Dropbox account. This enables you to play your game without worrying about losing your data.

Pros: The software is easy to use. Simply download the ROM image of the game and choose to open it with GBA4iOS and you are in business. The interface is customizable through the use of skins. You can design and implement your own skins to provide the ultimate level of customization. Dropbox sync allows you to automatically back up game saves to the Dropbox server. From there you can sync the games with other devices. You can even uninstall the software and retain the saves on Dropbox.

Cons: You can't install the app via the App Store. It is a separate download that must be downloaded and installed manually. The GBA4iOS software is only supported for iOS version 8.0.3 or less. Other versions of iOS are supported through a paid download from another site. Dropbox sync can be a bit confusing to get started. If there are game saves already in the Dropbox save location when you install GBA4iOS, games may show up as "conflicted", requiring additional configuration before they are available to sync.
