As many of you may already know, one of the benefits of jailbreaking is the wide variety of Console emulators one can download. Now you can enjoy these benefits on non-jailbroken devices as well, and I’m going to tell you how!
Step 1: Head over to emu4ios.net on your iDevice.
Step 2: Follow the instructions on their site.
Step 3: Once the app has installed, open it up and tap the search icon in the top right corner of your screen. This should take you to a google search page.
Step 4: Once you have downloaded the ROM you want to download, tap “Open in…” and select “GBA4iOS”
Step 5: Enjoy your newly downloaded Gameboy Advance Game!
EDIT: emu4ios.weebly.com has been hut down so you can now find the ROMs here: http://www.gba4ioskins.com/iemulators/
