Miyoo Firmware
Gaby Zenz
Note that due to demand, availability has been an issue. The cheapest prices will be through the official Miyoo store on AliExpress, but you will need to check periodically to see when the device will be in stock. You can also try third-party vendors like KeepRetro or DroiX, or you can pay a premium price on Amazon to get it more quickly.
To install new firmware, I recommend starting from scratch with a new microSD card. You could use a 16GB card to save on costs and keep your game library trim, or you could fill it up with the works. Personally, I use a 32GB card in mine, with only a few PS1 and Sega CD games taking up the majority of the space. Here are the cards I recommend:
The Miyoo Mini/Plus will come with a cheap SD card reader, but I recommend a nicer one instead. This one from Anker has never done me wrong for $15, and I also love this more fancy version with USB-C and USB-A connections.
One of the great things about a popular device like the Miyoo Mini is that the community comes together to find all sorts of accessories and solutions to every little need. There are plenty of choices when it comes to custom buttons and stickers, 3D-printed grips, and more. The original Miyoo Mini is approximately the same size as a deck of playing cards, so playing card cases are great alternative carriers for this device.
In the BIOS folder, add your BIOS file collection. You can simply copy/paste the files from your stock SD card, or add your own. On the stock SD card, you can find the BIOS files under RetroArch > .retroarch > System
To see a recommended list of BIOS files to add, head over to the Onion wiki page to see their list of emulators and recommended BIOS files for each system. For most systems, BIOS are not required, but can enhance the playing experience (like adding the original boot logo when starting up a game). For systems like PS1, Sega CD, and TurboGrafx-CD, BIOS are a necessary component.
When adding game files for systems that use the same RetroArch core file, you can create subfolders. For example, You could make Sega CD and Sega 32x subfolders inside of your Sega Genesis to clean up your front menu and streamline the navigation experience.
Recent updates from the community now allow for Nintendo DS emulation and the ability to play Pico-8 games (and its trademark Splore menu) natively. See the video above for a demonstration and walkthrough of the experience. Both apps will work fine on the Miyoo Mini and Miyoo Mini Plus, but for the online functionality of Pico-8, you will need a Miyoo Mini Plus connected to the Internet. Note that these apps require you to be running the latest version of OnionOS.
The Onion apps section has the ability to install your own themes, and you can also grab more from this massive themes repository. Moreover, you can adjust the themes to your liking, or create your own.
MiniUI is a lightweight launcher that is focused on simplicity, and works on both the Miyoo Mini and Miyoo Mini Plus. As expected, the installation of MiniUI is simple. Note that the Miyoo Mini firmware upgrade is not required for MiniUI.
Onion OS doesnt load some roms after following this guide.
GBA, FC, and SFC roms bring up a loading text then returns back to the Onion OS rom list. But if I Apps>RetroArch>Load Content>Navigate to ROM folder>Run rom with any core it works. I have verified the naming/path/capitalization is correct.
hi, im new to do this. i just got a miyoo mini v2 but without SD card from a third party. if i can get my own SD card will it be possible to download games onto my miyoo?
can anybody help me out with this?
The device wont take the update. When i plug it in, it skips the update and goes right to the charging symbol for both cards. I tried plugging it into the PC and an old brick. It does everything normally except loading the .img file.
I am following the Miyoo Mini videos since months, hesitated to order a Miyoo Mini because it seems to be too small for me (and has not been available at any second ) and missed the first Keepretro pre-order.
Today, I saw the announcement that KeepRetro has (only white) Miyoo Mini + available, so I ordered! Totally looking forward to this! ?
I was really on the presumption that the issue being a critical bug with the CFW. Because someone previously posted on Reddit about having installed a non-4.2.X version of OnionOS on his Mini Plus, which resulted in him losing charging capability as you did.
Hey Russ. Great guide. I did get stuck at one point and after working through it, thought it might be a good note to add. In my case I was using a flash disk that had a GPT partition table on it instead of the MBR partition table. Because of that, when attempting to use the guiformat tool to format the drive, it kept popping up an error saying the drive was in use. I did some digging, and that is when I came across a note somewhere talking about the partition table type. Then after following the guide below, I was able to convert it to an MBR partition table and then everything worked as it should. Just thought it might be worth adding a note or at minimum adding it to the comments here incase it helps someone else.

This section will cover the Miyoo products such as the Miyoo Mini and the Miyoo Mini Plus+. The process for these devices is very similar but may not be one-to-one, as the firmware is a low-level piece of software that interacts directly with the hardware, it is necessary to ensure that the software is made specifically for your device.
WARNING: Please ensure that you follow this guide exactly. If you use the wrong files, disconnect the device during the process, or otherwise fail to follow the outlined steps in some form. You risk bricking your device and rendering it inoperable. DroiX is NOT responsible in the event this occurs.
The first time you reboot into Android, there may be missing apps. If you leave the system for a short while, it will automatically start running a script to re-install the selection of stock apps on the device. After this is complete, it will reboot automatically.
If you have a Miyoo A30 retro gaming handheld and want to get the best performance from it, we highly recommend the Spruce custom firmware. It has a variety of improvements and features including optimised emulators, a cleaner frontend and game browsing experience, optimal settings and much more. Here is our guide on how to install Spruce.
Right click on the Roms folder and copy this to the root folder of the Spruce files you extracted on your PC. It will now copy your games to the PC. Depending on the number of games you have on the card this may take some time.
Load the MiniTool Partition Wizard software. Insert the micro SD card into your PC. The card will now appear in MiniTool. Double and triple check that you are using the correct drive for your micro SD card for the following process!
A menu will show with some options, for the File System option, change this to FAT32, then click on OK. Double and triple check you have chosen the correct drive for your micro SD card. Now click on Apply, the software will delete the original partitions, and then format the card to FAT32. This may take a short while if the card is large.
You can now copy all of the contents to your new micro SD card in one go. Navigate to the Spruce folder that you extracted and copied your games & saves to. Highlight all of the files and folders by pressing CTRL+A and then copy the files by pressing CTRL+C. Next navigate to your new micro SD card and press CTRL+V.
Everything will now be copied to your new micro SD card in one go. This may take some time if you have a large number of games. Do not remove the micro SD card or switch off the PC during this process.
We leave you this little 4-step guide where you have several links so that you can easily update the firmware of your Miyoo Mini retro console. This guide is for both the first version V1 and the second version V2.
1.The first link corresponds directly to the manufacturer's page to update the firmware of our operating system. It is an important step, because if we do not update the firmware version we will not be able to install the optimized system for the Miyoo Mini that the community has created and that is called OnionOS.
An essential step in setting up your Miyoo Mini for an optimal gaming experience is preparing and formatting the SD card correctly. This section will guide you through selecting the right SD card and formatting it properly.

Regularly check for updates to Onion OS and your emulators. Updates can bring new features, improved compatibility, and bug fixes. Staying current ensures the best possible experience on your Miyoo Mini.
While the Miyoo Mini offers a robust retro gaming experience, users might occasionally encounter issues. This section provides solutions to some of the most common problems you might face with your device.
I've recently started following the retro handheld gaming scene. It's a seemingly growing market of people, usually nostalgia-driven enthusiasts, who want to play discontinued games on a portable device using emulation. There was a peak in interest recently after the release of the Analogue Pocket, a high-end offering in what is typically a low-end market.
