|First things first, head into the Settings app on your iOS device. Choose General, and then Date & Time. Now set the date to any time before July 17, 2013.|
|Now open Safari and head to this page to get the most recent version of GBA4iOS.|
Follow the relevant link and you should get to a drop down list.
Choose GBA4iOS and hit done. Then hit "Confirm" on the pop-up.
|Once the app has installed, you should be able to set your date and time back to normal. Then try to load the app.|
If, for whatever reason, it doesn't work, try reinstalling the emulator, putting your phone in Airplane mode, or putting the date back before July when using the emulator.
|The emulator will now appear on your Home screen like any other app.|
You will get this pop-up the very first time you load GBA4iOS, but just hit 'Continue' and you'll be good to go.
|There are two ways to get ROMs onto the emulator.|
You can simply find a ROM file (or one that's in a zip file) on the internet.
Download it with Safari. Once it's done, you'll see a button that says 'Open in...'
Give it a tap, and choose 'Open in GBA4iOS' to move it to the emulator.
Alternatively, you can download the ROMs onto your computer, and transfer them across using iTunes.
Open iTunes, plug in your device, and choose it from the left-hand column.
Then click 'Apps' along the top bar, and you'll find GBA4iOS under 'File Sharing'. Simply drag your ROM file into this list and sync your device.
Whichever method you choose, simply pick the game from the ROM list in GBA4iOS and it will start playing.
Enjoy the game, you filthy pirate!
