The Nintendo Game Boy Advance was once one of the most popular handheld gaming devices. It featured major improvements over the previous Game Boy and Game Boy Color. With the GBA, you could finally play back-lit, full-color games all on one much sleeker device.

Gaming has made even more advancements since then, but the games of the GBA still remain among many people’s favorites. This is why many emulators, or software that allows you to play games of a certain system, were developed for the GBA.

    Most emulators are created to be used on a PC, however, there are some that can be downloaded and played right on an iOS device. If you’re wanting to play some GBA games this way, read on to learn how.

    1. Make sure your iOS device is still plugged into your computer, which has AltServer running in the background. Keep it plugged in until Delta is done installing.
    1. You can now open the Delta GBA emulator!

    Now that you’ve downloaded the actual emulator onto your device, you’ll need to get some games to play. Thankfully, this part is pretty easy and is done right from your iOS device.

    How to Download GBA Games

    First, make sure the Delta app opens up on whatever iOS device you plan to use. In order to play games on this emulator, you’ll have to download what are known as ROMs, which is a file of the game that can be played on emulator software.

    Here’s how to download some for the Delta emulator:

    1. Head to Safari on your iOS device.
    1. Enter in a ROM website, and find a game you want to play. (Note: be careful of which files you download. If the site or the file seems fishy, don’t download anything.)
    1. Select the Download button on the ROM page, and confirm the download.

    1. In the top right corner of Safari, you should see a blue download icon. Once the ROM downloads, you can go back to the Delta app.

    Using the GBA Emulator

    After all the downloading and set-up process, actually playing your GBA games is a breeze. You use the on-screen controls just as you would a real Game Boy Advance, and the emulator works very well as long as you download ROMs from a reputable source.

    To save and load your game, enter cheat codes, and more, you can press the Menu button in the bottom left. You can also exit any game back to the main Delta menu this way.

    If you’re playing a game from a system other than GBA that Delta supports, you can select the Settings icon from the main menu and change the controller skin so that it’s easier to play.

    You can also connect Bluetooth controllers in the Settings, under Controllers. Just select your Bluetooth controller and you’re good to go.

    This emulator is great because not only can you download and play hundreds of games, you can also play them all on-the-go, which you wouldn’t be able to do with just a PC GBA emulator. For anyone into retro gaming, I highly recommend setting Delta up on your iOS device.
