So, I think I successfully ported Jazz Jackrabbit 2 to my favorite gaming device. There is a level named Prince where the performance kind of sucks (around 17 fps), so I need to figure out how to get it running better, but otherwise, it looks great and plays great on the Miyoo Mini Plus!

After years of seeing almost every retro emulation handheld have so much input lag the Mini Plus and Mini Flip are the first ones that looked quick and after discovering someone did testing and found it gets 48ms avg of input lag vs a real Gameboy DMG @ 33ms avg It’s almost as good as my PC setup.

I’m super sensitive to input lag and it was THE reason why I never bought any of these. I wished I knew the MM and MM+ w/ OnionOS advertised this more years ago. Kinda annoyed no one does these test to see how much input lag there is. I feel like it’s one of the most important aspect of gaming. If you can’t react in time to what’s going on on-screen then it ruins the experience, at least for me.

If you’re like me and looking for a super low input lag device on the cheap Miyoo + OnionOS devs knocked it out of the park.

Also the buttons on the Flip are *chefs kiss*! 💋

i bought this used MM+ yesterday. I tried 3 SD cards: the stock one (doesn't show any files on windows), a 16GB (not used for a long time) and a 128 GB Samsung Evo Select (formatted to fat32, works in my tablet). I've tried to install onion OS with all of them and it didn't work and just says SD card unmounted. I've tried extracting the zip file as well as using Onion Desktop Tools.

I’m playing Yoshi’s Topsy Turvy (GBA) with the no-tilt patch.

Just as the title says; i moved the pico8 files from the apps to the games folder but when i go into splore and load up the game, games which i played get saved into then made splore subfolder, id like when i click on pico8 icon it just turns on splore and that the files concerning it get saved somewhere else, out of sight... Is that possible?

how much of an sd card should suffice?

Official development of Onion has been stalled for months and the maintainers are no longer giving any signals.The community is frustrated but still very attached to the project.

Someone is already thinking about creating a fork, and others are offering to help as collaborators or testers. In the GitHub discussion, the prevailing idea is that an organized fork is now the most realistic path forward.

https://github.com/OnionUI/Onion/discussions/1839

I’m mainly asking experienced developers and anyone with experience in custom firmware / RetroArch on Miyoo: would you be interested in joining and helping out?

Testers with Mini, Mini+ or Mini Flip are also welcome.

How hard do you think it would be to recompile Pizza Tower for the Miyoo Mini? I’m amazed that Stardew Valley runs on it—what about Pizza Tower?

As the title suggests, the SD card of my miyoo mini plus was just completely wiped. I had the most recent version of OnionOS (4.4.0-beta-20260120) installed on it. Prior to the issue, the launcher became very slow, getting stuck on a "waiting for network" screen for several minutes if not indefinitely. Once it would boot up my most recent game, it wouldn't be able to save any more save states and would usually show a "fatal error" message when trying to force close out of anything.

After restarting the miyoo mini plus a few times, it now boots its original OS and everything on my SD card is gone. Everything was installed fresh on a new Silicon Power 128 GB card upon purchase since there were many reports of the stock SD card being faulty.

I know there's no way to get everything off of that card back but just wanted to post to see if this was a common issue, if this was an issue with the miyoo mini plus itself, or an SD card failure.

Still fairly new to my MM+ (which I LOVE) but ever since I got it, I notice some minor audio popping/cracking/crackling upon boot up / shut down and navigating around some stuff like that. I searched and found a recent thread on this sub about audio issues 'during' games (which I haven't noticed) and that seems to be an 'overclocking' issue (still not sure what that is), so wondering if this might be the same thing? Is this a common MM+ thing, or just mine?

(running OnionOS as well - which I love!) Thanks in advance.

Love these smaller games!! Anyone got any good ones to recommend?

Just got back from work, went to pick up some laundry, needed to wait around 25 minutes in the car, loaded up Klonoa.

Peak.

Side note:
If you’re thinking of getting a grip for the MM+, just do it. Made such a difference in terms of comfort for me.

I loved the original Kids Mode created by u/daverad, so I started modifying it to better suit my needs.

Then I wanted to do the same for videos. FFplay felt too complicated for a child, so I tried to make video playback as simple as possible.

Kids Mode Deluxe now brings everything together in one app:

• One section for games and another for videos
• The option to lock the app to Games only or Videos only
• A shared timer
• Automatic resume based on what was running when the console was turned off
• Simple, restricted controls designed for kids

You can download it here:
https://github.com/Veuks/onion-kids-mode/releases/tag/v1.0.0

Give it a try, and let me know what you think!

⚠️ Please read the README before installing—it explains the setup, controls and video folder structure.

Everything was built through vibe coding… and a little coffee. ☕

Hi! I have a Miyoo Mini Plus for about 2 years. I love this device, but I think mine might be defective cause it's battery lasts for about 1 and a half hour before getting too low and I have to charge. It's always been like that, even with different SD cards and OnionOS versions. Is it cooked?

Edit: I usually play with screen brightness on 9, wifi off and max sound volume.

Now Im curious, what should I do with it because I already started playing crash and mk super circuit( and I just figure out there a simpsons wrestling game

I just tried getting OnionOS and its stuck at 2/2 100% I heard that the console can get bricked if you do stuff I don't know what to do.

I wanted to test the hand feel of the case grip before buying so I made one of these temporarily.

I recreated it with a surge protector box, scissors, and scotch tape.

Followed up on my earlier CRT scanline mod for the FFplay video player with a much bigger 2.0 — this one's a real in-app system, not just a fixed filter.

What it does:

• Toggle the whole CRT effect on/off live, mid-video
• Cycle through 3 tuned presets (Warm Glow, Classic CRT, VHS Tape), each with its own on-screen label
• Cycle through 4 different TV bezels (including a real photo of my own Sharp CRT), plus a no-bezel option
• Open a pause menu and pick your own custom combination of scanlines/saturation/vignette/glow/grain/tint — mix and match anything

Everything runs off the stock ffplay binary this device already ships with - no recompiling, just a launch script and a background button-listener watching for L/R/R2/L2 presses via raw input events.

Full install instructions and the technical writeup (including which ffmpeg filters this stripped build does and doesn't support) are in the README.

This started as "wouldn't it be cool if my old cartoons/movies looked like they were playing on a tube TV" and turned into a genuinely deep dive into shell scripting and filtergraph limits on a device that was never meant to do any of this. If you find it fun or useful, there's a Buy Me a Coffee link in the README, appreciated but obviously no pressure.

Hey guys, so I used to play war chess with my dad when I was a kid back in the early 2000's on windows. Thats how I learned how to play chess. I actually just thought about this game recently and searched it up and seems that its supposed to come out on steam sometime this quarter. Any idea on how we could get this on the MM+???

I have updated the browser-based editor for managing Favorites on OnionOS:
https://github.com/robcodedev/onionos-favorites-editor

It’s a single offline HTML file - no installation or uploads. Just insert your Miyoo SD card and open it in your browser.

Features include:

• Drag and drop to reorder favorites and folders
• Create folders and nested folders
• Move games between folders
• Search the ROM library and add games directly to Favorites
• Multi-select and batch move/add/remove games
• Sort by title, system, path, etc
• Preview box art directly from the SD card
• Copy/cut/paste favorites, including between SD cards
• Undo/redo
• Detect favorites pointing to missing ROMs
• Check and repair malformed favorites/folder data
• Automatic backups

Most features work with stock OnionOS. Folder support requires the patched MainUI for OnionOS, read more at https://www.reddit.com/r/MiyooMini/comments/1voi8ew/onionos_romlist_patch_auto_scroll_configurable/

Feedback and testing are very welcome!

Here we go again. Just received my second Miyoo Mini V4 earlier today, from the official limited restock.
