Reminiscing about the thrill of conquering your first level in Super Mario or the epic battles in Final Fantasy? For many of us millennials, Nintendo and other retro games were a defining part of our childhood. But wouldn’t it be amazing if you could revisit those classic games on the go, right on your iPhone?
With the Delta emulator, that dream can be a reality, all without costing you anything. Keep reading to learn how to load and play game ROMs in the Delta emulator on your iPhone and transform your device into a retro gaming beast to relive your fun memories.
What is Delta emulator on iPhone?
The Delta emulator is a free retro gaming emulator designed for iPhones. It allows you to play video games originally developed for older gaming systems by Nintendo on your iPhone by simulating their hardware. Instead of using a game cartridge, emulators allow you to play using ROMs extracted from the cartridge.
In the past, installing Delta required sideloading the app via AltStore or other alternatives. This used to be a very time-consuming process, and you needed to resign the app every seven days. Thankfully, as of 2024, Apple has updated its App Store policies to allow app developers to publish emulators on the App Store, opening Delta to more users looking to play retro games on an iPhone.
What ROMs are compatible with Delta?
Delta supports ROMs from several retro consoles that were released during the late 80s and 90s. Here are all the ROMs that work with the Delta emulator as of the time of writing:
- Super Nintendo Entertainment System (SNES)
- Nintendo Entertainment System (NES)
- Game Boy / Game Boy Color (GBC)
- Game Boy Advance (GBA)
- Nintendo 64 (N64)
- Nintendo DS (DS)
Besides these consoles, the developers of Delta are already testing to bring support for Sega Genesis / Mega Drive (GEN) and other game ROMs in Delta.
Where can I find game ROMs for Delta?
Just a simple Google search should reveal several sources from where one can download game ROMs for Delta. However, it’s up to you to verify the legality of these sources, as ROMs often lie in the grey area of copyright laws. The only legal way you can get ROMs for Delta is to manually extract them from your game cartridges using a device like GB Operator. It’s fine to use your ROMs for personal use as long as you’re not sharing them with others.

How to connect a game controller in Delta emulator iOS

- Put your controller in pairing mode and bring it near your iPhone.
