Apple retailers frequently discount iPhones, Macs and iPads for Black Friday.
GBA4iOS Debuts 2.0 Update for Game Boy Emulator With iPad Support, Easy Installation
More importantly, the software is now much easier to install, requiring neither a jailbroken device nor a work around to set the device clock to 2012. Prior to the 2.0 update, installing GBA4iOS without jailbreaking required an iPhone's date to be set to 2012. Though it doesn't require an initial date change, GBA4iOS 2.0 does carry a warning that the device clock may need to be set back to 2/19/14 if the app fails to open.
With GBA4iOS 2.0, gamers can play Game Boy Advanced, Game Boy Color, and original Gameboy ROMs directly on their iPads and iPhones, but the software is only compatible with devices running iOS 7. GBA4iOS 2.0 is distributed using an Apple Enterprise certificate, which are designed to allow companies to distribute iOS apps internally.
Downloading games for GBA4iOS previously required navigating outside of the app to find ROMs, but the newest version includes an in-app web browser that can be used to download games from any ROM website. GBA4iOS 2.0 also includes full support for cheats, accepting five different code formats covering everything from Game Genie to Action Replay.
The GBA4iOS update includes an array of controller skins for Game Boy Advance and Game Boy Color games and it supports third party controller skins. It also offers full iOS 7 controller support, Dropbox integration, and "Event Distribution" to allow GBA4iOS unlock and distribute features that are not normally included within games.
While several emulators have snuck into the App Store via shell apps, they are always short-lived as Apple pulls the apps within hours or days of release. GBA4iOS is able to overcome Apple's restrictions as it is not installed via the App Store. Instead, GBA4iOS can be installed directly on an iOS device from the website, by tapping the download link on an iPad or iPhone.
Update: Apple has revoked the enterprise certificate that GBA4iOS used to install itself on iOS devices, which means installs now require setting a device date back to February 18, 2014 before downloading the software. After installation, the date on the device can be changed back to the present time.
