Preparing for Onion OS Installation
Before installing Onion OS, you’ll need a microSD card and a computer. Download the Onion OS V4;2 image and the necessary desktop installation tool for a smooth process.
Required Materials: SD Card & Computer
Successfully installing Onion OS on your Miyoo Mini Plus hinges on having the correct materials readily available. First, a microSD card is absolutely essential; a capacity of 64GB or 128GB is highly recommended to comfortably accommodate both the operating system and a substantial library of ROMs. Ensure the SD card is of a reputable brand for optimal performance and reliability.
Secondly, you’ll require a computer – either a Windows, macOS, or Linux machine will suffice – with a functioning SD card reader. This reader can be built-in or external, connected via USB. A stable internet connection is also crucial for downloading the Onion OS image and the accompanying desktop installation tool. Having these components prepared beforehand will streamline the installation process considerably.
Downloading Onion OS V4.2
Acquiring the Onion OS V4.2 image is the first step towards transforming your Miyoo Mini Plus. The official Onion OS website is the safest and most reliable source for downloading the firmware. Be cautious of third-party sites, as they may host outdated or compromised versions. Navigate to the downloads section and locate the V4.2 image specifically designed for the Miyoo Mini Plus.
The file will typically be a compressed archive (like a .zip or .7z file). Once downloaded, extract the contents to a convenient location on your computer. This extracted folder will contain the necessary files for the installation process. Double-check that the download completed successfully and isn’t corrupted before proceeding.
Downloading Necessary Tools (Desktop Tool)
The Onion OS Desktop Tool simplifies the installation process significantly, especially for beginners. This user-friendly application automates the SD card formatting and firmware flashing, reducing the risk of errors. You can find the Desktop Tool on the official Onion OS website, usually located in the same downloads section as the OS image itself.
Download the version compatible with your computer’s operating system (Windows, macOS, or Linux). Once downloaded, install the tool following the on-screen instructions. The Desktop Tool provides a graphical interface, making the entire process more intuitive than manual methods. It’s a highly recommended tool for a smooth and hassle-free installation experience.
Installing Onion OS ⎯ Step-by-Step
Installing Onion OS involves formatting your SD card, utilizing the Desktop Tool to flash the firmware, and then copying the necessary Onion OS files onto the prepared SD card.
Formatting the SD Card
Formatting the SD card is a crucial first step for a successful Onion OS installation. The recommended method utilizes the Desktop Tool, simplifying the process considerably. Before proceeding, ensure you’ve backed up any important data on the SD card, as formatting will erase everything.
Within the Desktop Tool, select the formatting option, typically choosing FAT32 as the file system. This ensures compatibility with the Miyoo Mini Plus. The tool will handle the entire formatting procedure, preparing the SD card to receive the Onion OS files.
Alternatively, you can use standard disk management utilities on your computer, but the Desktop Tool offers a more streamlined and reliable experience specifically tailored for the Miyoo Mini Plus.
Using the Desktop Tool for Installation
The Desktop Tool is the easiest method for installing Onion OS on your Miyoo Mini Plus. After downloading and launching the tool, connect your formatted SD card to your computer via a card reader. The tool will automatically detect the card, presenting you with installation options.
Select the appropriate Onion OS version (V4.2 is current) and follow the on-screen prompts. The tool handles partitioning and file transfer automatically, eliminating manual steps. This process typically takes only a few minutes, making it incredibly efficient.
Ensure a stable connection during installation to prevent errors. Once completed, safely eject the SD card, and you’re ready to boot your Miyoo Mini Plus with Onion OS.
Copying Onion OS Files to the SD Card
After formatting the SD card, you’ll need to transfer the Onion OS files. Unzip the downloaded Onion OS V4.2 archive to your computer. Locate all the extracted files and folders within the unzipped directory. Carefully copy all of these files and folders directly to the root directory of your SD card – do not create any additional folders.
Ensure that all files are successfully copied before ejecting the SD card. Double-check to avoid missing any crucial components. A complete transfer is essential for a successful boot. Once verified, safely remove the SD card from your computer and insert it into your Miyoo Mini Plus, preparing for the first boot.

Setting Up Wi-Fi Connection
Connecting to Wi-Fi is crucial for online features like scraping metadata for your games and downloading updates. From the Onion OS home screen, navigate to ‘Settings’ and select ‘Wi-Fi’. The system will scan for available networks. Choose your desired network from the list and enter the password when prompted.
Ensure you input the correct credentials for a successful connection. Once connected, a Wi-Fi icon will appear in the status bar.

Onion OS also offers options for scaling and aspect ratio, impacting how games are presented. Fine-tuning these settings can optimize the visual quality of different emulators. Consider adjusting these based on the specific game you are playing for the best results. Remember to save your changes before exiting the display settings menu.
Adding ROMs to Your Miyoo Mini Plus
Adding ROMs is simple: create dedicated folders for each system within the ROMs directory on your SD card, then transfer your game files.
Creating ROM Folders
Organizing your ROMs is crucial for a clean and functional setup on your Miyoo Mini Plus with Onion OS. Within the main ROMs directory on your SD card, you’ll need to establish dedicated folders for each gaming system you intend to emulate.
For example, create folders named “Nintendo 64”, “Game Boy Advance”, “Super Nintendo”, or “PlayStation”. Consistent and accurate naming conventions are highly recommended for optimal compatibility and display within the EmulationStation interface. This ensures the system recognizes and categorizes your games correctly.
Avoid spaces or special characters in folder names to prevent potential issues. A well-structured folder system will significantly improve your overall gaming experience, making it easier to locate and launch your favorite retro titles.
Transferring ROMs to the SD Card
Once your ROM folders are created, transferring your game files to the SD card is straightforward. Connect the SD card to your computer using a card reader. Then, simply copy your ROM files into their corresponding system folders. Ensure the ROM files are compatible with the emulators supported by Onion OS – common formats are .zip, .smc, .gba, and .iso.
After the transfer is complete, safely eject the SD card from your computer. Reinsert it into your Miyoo Mini Plus. The device will scan the ROMs directory upon booting, populating the EmulationStation interface with your games.
Remember to verify the ROMs are functioning correctly after the initial scan.

Onion OS on the Miyoo Mini Plus boasts broad compatibility with numerous retro gaming ROM formats. Commonly supported formats include those for classic consoles like Game Boy Advance (.gba), Super Nintendo (.smc, .sfc), and Sega Genesis (.bin, .gen). PlayStation Portable (.iso, .cso) and PlayStation 1 (.iso, .bin, .cue) games also function well.
Arcade ROMs in .zip format are generally supported, alongside Nintendo 64 (.n64, .z64) and Dreamcast (.cdi, .gdi) titles. Compatibility can vary based on the specific game and emulator core used. Experimentation is key to ensuring optimal performance.
Refer to online resources for detailed format lists.
Customization and Tweaks

Installing Themes
Onion OS offers a vibrant community creating custom themes to personalize your Miyoo Mini Plus experience. These themes alter the visual appearance of the interface, including backgrounds, icons, and fonts, providing a fresh look.
Typically, theme installation involves downloading the theme files – often in a compressed archive – from online sources like Reddit’s r/MiyooMini. These files are then transferred to the correct theme folder on your SD card, usually located within the ‘themes’ directory. After transferring, a reboot or restarting the Emulation Station is required to apply the new theme.
Many tutorials, including those found on YouTube, visually demonstrate this process, making it accessible even for beginners. Remember to back up your existing theme before installing a new one, allowing for easy reversion if needed.
Adjusting Performance Settings
Onion OS provides options to fine-tune performance on your Miyoo Mini Plus, balancing visual fidelity with smooth gameplay. Access these settings through the main menu, typically within the ‘Settings’ or ‘Performance’ sections of the Emulation Station interface.
Key adjustments include CPU clock speed and GPU settings. Increasing these can improve performance for demanding games but may reduce battery life and generate more heat. Conversely, lowering them can extend battery life at the cost of graphical detail. Experimentation is key to finding the optimal balance for your preferences.
Online resources, like guides on Mechdiy, often suggest specific settings for different game types. Remember to test changes thoroughly to ensure stability and a positive gaming experience.
Emulation Station Configuration

Double-check that all files were correctly copied to the SD card, and that the installation process completed without errors. Sometimes, a complete power cycle – holding the power button for an extended period – can resolve temporary glitches. If the issue persists, consider downloading a fresh copy of Onion OS to rule out a corrupted download. Consult the r/MiyooMini community on Reddit for further assistance and specific troubleshooting tips from experienced users.
