Step-by-Step Guide to Activate Delta Emulator on abxylute M4 & RetroArch on One Pro

Thanks to emulators and advanced gaming hardware, retro gaming has been more accessible than it ever was. It doesn’t matter if you’re an iPhone user using the compact abxylute M4 controller or an Android gamer with the One Pro handheld; this ultimate guide will walk you through the entire setup process to make sure you have the best emulation experience for your device.

Understanding Your Setup

Delta Emulator & abxylute M4

Before you start the activation process, it’s essential to understand the specifications and requirements of what you’re working with. The Delta Emulator is an all-in-one iOS-exclusive emulator that lets you play classic Nintendo systems like the NES, SNES, Nintendo 64, Game Boy, Game Boy Advance, and Nintendo DS.

Meanwhile, the abxylute M4 is a pocket-sized MagSafe controller that was specifically designed for gaming with your mobile device, especially the iPhone. It weighs just 55 grams and can be connected using Bluetooth. Most importantly, its battery can last up to 10-13 hours.

RetroArch & abxylute One Pro

On the Android side, the abxylute One Pro is a cloud-focused handheld that supports Xbox Cloud Gaming, GeForce NOW, and PlayStation Plus. In addition, it is powered by an Android 13 operating system with a MediaTek Genio 510 CPU. While it was designed for cloud gaming, it can also run emulators like RetroArch, one of the most versatile multi-system emulator frontends.

How to Activate the Delta Emulator on iPhone with M4 Controller

Step 1: Install the Delta Emulator

The easiest way to get Delta on your iPhone is by downloading it through the official App Store by simply searching “Delta Emulator”. The app is completely free but requires iOS 10 or later because it’s optimized for iPhone 10 and newer models.

For users in the European Union (EU), you’ll need to use AltStore PAL due to Apple’s Core Technology Fee regulations. Although it has a €1.50 annual subscription paywall, you can still have the full-featured Delta experience. Download Altstore from altstore.io and simply follow the installation instructions. Finally, you can download Delta directly from AltStore.

Once you’ve installed Delta Emulator, you have to navigate to Settings > General > VPN & Device Management, tap on the developer profile, and click on “Trust.” This is so that Delta can run without any restrictions.

Step 2: Obtain Game ROMs Legally

Delta doesn’t come with pre-installed games, which is why you’ll need to provide your own ROM files. The best option is Homebrew Hub (hh.gbdev.io), where you can get homebrew games for Game Boy and Game Boy Advance. However, you can also purchase games from Steam retro collections.

To import the game to Delta, follow the instructions below:

1. Once you’ve downloaded the ROM file on your iPhone, save it to your Files app in the Downloads Folder.
2. Open Delta, tap the “+” icon, and then select “Files,” where you can navigate to your Downloads and select the ROM file.
3. Finally, click “Open,” and the game will instantly import into your library.

Step 3: Setting Up the abxylute M4 controller

The M4 controller’s setup is very straightforward. If you have an iPhone 12 or newer models with MagSafe, just snap the magnetic ring onto your phone’s back. For older iPhones, you can use the included magnetic adhesive ring by attaching it to your phone or case.

To activate Bluetooth pairing, press the pairing/Bluetooth button located on the side of the controller for around 3 seconds or until the LED indicator turns on. Immediately open the Bluetooth Settings of your iPhone and look for “abxylute M4” in the available devices list. Tap to pair, and you’re done!

Step 4: Connecting M4 with Delta

Delta will immediately detect the M4 controller as an MFi-compatible device, so most games will work instantly. However, you can customize your controls by opening Delta's settings, scrolling to “Controllers” and tapping “Player 1”. You can then select the M4 controller from the list.

You can freely experiment by remapping buttons, selecting your game system, and more!

Activating RetroArch on abxylute One Pro

Step 1: Install RetroArch

Since the abxylute One Pro already runs on Android 13, you can just search “RetroArch” on the Google Play Store and install it directly. However, it may be outdated. So we suggest that you download the emulator from the official RetroArch website. You can choose from the latest Nightly build with cutting-edge features or the Stable version with fewer bugs.

After you’ve downloaded RetroArch, open your File Manager, go directly to your Downloads Folder, and then click on the RetroArch APK file. You may need to allow APK installations in your settings before you can proceed, so make sure to double-check.

Step 2: RetroArch Configuration

As you launch RetroArch for the first time, you need to grant all necessary permissions, including file access. Your first task should be updating core files by navigating to Settings > Online Updater and selecting each menu item starting with “Update….” This is to make sure that you have the latest emulator cores and compatibility data.

Step 3: Download Emulator Cores

Cores are the actual emulators you run through RetroArch. From Settings, go to Online Updater and select “Core Downloader.” You’ll then be given a list of the available cores. However, for the One Pro, focus on these recommended cores:

• Game Boy/Color: Gambatte
• Game Boy Advance: mGBA
• NES: Mesen or Nestopia UE
• SNES: Snes9x (Current)
• Nintendo 64: Mupen64Plus-Next
• PlayStation 1: Beetle PSX HW or DuckStation
• PSP: PPSSPP
• Nintendo DS: melonDS

Just tap each core, and the download will start automatically. You can even download multiple cores on your device.

Step 4: Adding ROMs and Playing Games

We suggest creating a dedicated folder on your One Pro for game ROMs. Create a general “ROMs” folder and then subfolders for each core. After that, you can transfer your ROM files to their respective locations using a USB connection or cloud storage.

To start playing, open RetroArch and click on “Load Content” from the main menu. You can then simply navigate to your ROMs folder and select a game. However, you can also use RetroArch’s automatic game scanning. Go to Main Menu > Import Content > Scan Directory, select your ROMs folder, and RetroArch will organize everything for you.

Congrats! You can now start playing emulated games on your One Pro.

Conclusion

Setting up the Delta Emulator with the abxylute M4 and RetroArch on the abxylute One Pro lets you open up decades of gaming history at your fingertips. Both setups offer unique advantages. Whether it’s the M4’s portability or the One Pro’s wider system support, whichever one you choose, you can easily relive your childhood and play classic games anywhere, anytime.
