We have used our expert knowledge to tune the configuration of your Miyoo handheld. If you discover other tips or configurations that enhance your experience, please use the contact form to let us know. Here’s a list of the changes we’ve made.
The microSD cards that Miyoo usually supplies with its handhelds are unbranded and we are not satisfied with their reliability. Therefore, we ship these devices with brand-name microSD cards.
We are so confident about the quality of these cards that we provide a lifetime guarantee.
It’s important to make a backup
Even with the lifetime guarantee we give our microSD cards, it is still recommended that you backup your card(s) as soon as you receive your device. See How to backup your retro handheld’s microSD card(s)
We have replaced the stock firmware with the OnionOS custom firmware. In our testing, OnionOS provided excellent balance between ease of use and performance. We have further refined the configuration of the firmware with settings specific to the Miyoo Mini.
Powering on the device
POWER button for a few seconds.
Turning off the device
POWER button for a few seconds. Your device will now power down safely. If a game is open, your Miyoo Mini will automatically create a save state before shutting down1. When you next start that game, it will continue from that save state.
If the device crashes, and the above method doesn’t work, a hard shutdown can be performed by pressing
START + SELECT + R2 + L2.
This method should only be used as a last resort as it risks data corruption.
This is only a light sleep mode and still drains the battery. We do not recommend using it for long periods of time.
Navigate between systems
Most of the systems supported by this device can be found in the
Consoles section. The
Expert section contains systems that are more experimental. The games you play from this section may be a little more prone to crash. We’ve included them because we feel that what they add to your gaming experience is worth it.
Navigate through a game list
To speed up the process of scrolling through a game list, use
R1 to move a page at a time.
You may also find it convenient to use the
Recent section to find your most recently played games.
Quitting a game
If you power down the device with a game still running, it will automatically create a save state while it switches off1.
FUNCTION button is the small, circular button in the middle of the device. The OnionOS documentation calls this the
MENU button. The following hotkeys work when pressed together with the

Additional hotkeys, not used in combination with the
See https://github.com/Sichroteph/Onion#shortcuts for more.
You can add a game to the
Favorites section by pressing the
FUNCTION2 button and selecting
Add as favorite.
On-screen keyboard (for home computer systems)
Home computers – such as the Amiga, Commodore 64, Amstrad CPC, and ZX Spectrum – included a keyboard. Games for these systems often require keyboard input actually to start the game-play or to choose joystick mode.
To bring up the on-screen keyboard, for most systems, press
SELECT. For the Amstrad CPC, press
If the system seems to be waiting for you to do something, try bringing up the on-screen keyboard and pressing
If a game asks for an input method, we recommend that you choose
Joystick or, in the case of the ZX Spectrum,
Famicom Disk System (FDS)
Famicom Disk System games often require you to change discs. Use the following input sequence to do so:
R2to eject the current disc
L2to select side B
R2to load side B
Fast-Forward and Rewind
Your Miyoo Mini, with OnionOS, allows you to Fast-Forward or Rewind games.
Sometimes you may wish to
Rewind the action in a game to undo a quick fail. Press and hold
FUNCTION + L12.
Not enabled on all consoles
Rewind are enabled on most systems, but there are exceptions; such as the
Virtual Boy, and
ZX Spectrum, where there would be an adverse effect on performance.
Autosave & save-states
On most systems, when quitting a game, it will automatically create a save-state1. When next launching the game it will start the action at the same point.
Ports section contains games that run natively on your Miyoo Mini, without the use of an emulator. This means that games can run more smoothly and with better performance. It may be interesting to compare the Doom port with the same game on emulated systems.
Pico-8 and Tic-80
Tic-80 are Fantasy Consoles. These aim to create the experience of retro-gaming without the need to emulate a real hardware console.
A fantasy console is like a regular console, but without the inconvenience of actual hardware. PICO-8 has everything else that makes a console a console: machine specifications and display format, development tools, design culture, distribution platform, community and playership. It is similar to a retro game emulator, but for a machine that never existed.zep, “What is a Fantasy Console?”, https://www.lexaloffle.com/pico-8.php?page=faq
It’s remarkable what some game developers can do within the constraints of these fantasy consoles, and their games are worth checking out. A great example is
Celeste, originally made for Pico-8, and is included with your device.
Setting the clock for Pokemon games
The Miyoo Mini does not feature a Real-Time Clock (RTC). It compensates for this by adding 4 hours to the time upon every reboot.
For games that may require finer control over the stored time, such as the Pokemon games, you can use the
Set Clock app. Set the time and date to whatever you wish. Again, 4 hours will be added when you next start your device.
Your Miyoo Mini comes with a range of themes. You can choose your preferred theme by running
App -> Theme Switcher.
If your chosen theme features background music, its volume level can be configured in the
Show the Retroarch menu
FUNCTION + SELECT2 buttons when playing a game that uses a RetroArch core. You can adjust many settings here, but OnionOS has done a good job of optimizing these for you.
You can also see the RetroArch menu by running the
RetroArch item in the
Onion Launcher mode (this is clever)
Onion Launcher mode will boot straight into the last game you were playing, starting at the point where you last quit the game1. It also offers stream-lined navigation between your ten most recent games.
Enable Onion Launcher mode
App section, run the
Onion Launcher item. This will enable
Onion Launcher mode on the device.
Now power off your Miyoo Mini. When you power on, it will automatically start the last game you were playing at the most recent save-state.
If you power down the device while a game is running, it will automatically create a save state1.
Navigating between recent games
If you quit the game (using the
FUNCTION2 button) it will exit into
Onion Launcher mode. If you press
Right on the
D-pad, you will navigate between your ten most recent games. Press the
FUNCTION2 button to launch the game with its most recent save-state.
Disable Onion Launcher mode
- Quit the game using the
FUNCTION2 button to get into the
START(this takes you to the usual OnionOS menu)
- go to the
Appsection and run the
Onion Launcheritem again.
If want to let someone else use your Miyoo Mini, but you’re concerned they might mess up your save points or configuration, you can put the device in
App -> Guest mode and switch off the device. When you switch the device back on, your guest can play games without overwriting your save states.
To return the device to normal, just run
App -> Guest mode again.
- This is the Operating System that runs on your Miyoo retro handheld device. It provides numerous improvements to the stock firmware.
- Retroarch provides most of the cores/emulators that run the provided games. The Retroarch menu is used to configure its cores.
- A Core is an emulator that has been adapted to work with Retroarch.
- An emulator allows your device to pretend that it’s a different device. For instance, the PCSX4ALL emulator enables your Anbernic retro handheld to pretend that it’s a PlayStation and run games designed for the PS1.
- A few systems do not support this feature, including ARCADE and Pico-8
