Miyoo Mini Onion OS full simple upgrade tutorial | KEEP YOUR GAMES | **OUTDATED**

This is the best, concise video on how to do this, and the only one I've seen that actually tells us how to keep our games! Thank you so much, subbed 🤘

[@RetroBreezeYT]

You're welcome! I'm glad it was helpful!

[@JojoMinimalSchizo]

I followed your steps and it all worked out very well. Thanks man! I used a Chromebook instead of a Windows PC and it all still turned out fine. My only minor problem now: In PS1 the Onion OS now says it does not find a BIOS. But all PS1 Games I've tried so far still run great..

[@RetroBreezeYT]

Thanks for the feedback! Actually my video has a silly mistake. Instead of copying the system folder to Retroarch/.retroarch/system, you should copy the contents of the system folder to the BIOS folder on the SD Card root (make it if it doesn't exist). I'll note this in the description and in the video if possible!

[@JojoMinimalSchizo]

@@RetroBreezeYT that's true. I read a lot of stuff and then I got the BIOS from the PSP and put it there. Also important: If you add additional BIOS you have to be careful because it's case sensitive. My PSP BIOS came named in all big letters and I had to rename it in all small letters to work. Took me a lot of additional reading also making .cue files and stuff. But finally my FF7 is working and the PSP BIOS for PS1 is recognized. - Oh and even with the mistake you made, I still found your Video to be the most helpful guide for this I've seen so far. Oh and sorry for maybe bad English. I'm not a native speaker...

[@JojoMinimalSchizo]

@@RetroBreezeYT Oh, another question: in the expert part of the Onion OS there is the Arduous Emulator for Arduboy Games. I've installed it and download 2 ROMs (Siren and ArduVenture) both are recognized, but wont start and revert to the game selection menu. Any Ideas?

[@KRATOS_XIX]

@@RetroBreezeYT I have a few question regarding the "Theme Switcher" in the Apps menu, I have 13 themes in there that came from the update but only 6 of them have an image preview, the rest just shows a text saying "No preview available"? How do I fix this? My onion version is 3.10.5

[@RetroBreezeYT]

The six themes that have preview images are the ones included with Onion OS. The remaining themes without previews come from the TF Card(1) folder for the official firmware update. For some reason miyoo didn't include the preview.png file for those themes. You can either add your own preview.png (any image at 480 x 360 resolution) to the theme folder, or try to find a download that includes the preview. Most (but unfortunately not all) of them are on this page: github.com/jimgraygit/Onion/wiki/4.-Theme-Repository

Great video....I did all this on a fresh install but when I go into my Onion OS, there are no Games or Consoles showing under 'Games'. What have I missed?

Did you copy your games over to the SD Card after installing Onion? Also, did you go to the package manager and activate the systems you want?

[@Dan-sr2lc]

for Imgs aka boxart, each system .pngs have to be copied into Roms/"systemname"/Imgs folder as the emu configs point there. You could just change the path in the config but I prefer the .pngs to be separate.

@@RetroBreezeYT thank you! So for the miyoo mini you technically don’t have too. I also had another question. If you’re using a new micro SD card do you have to install the latest miyoo mini update on it ? Or do you simply skip the update if it was already done on the old SD card? If that makes sense.

[@RetroBreezeYT]

@@manny1524 @Manny The firmware update itself remains on the Miyoo's internal storage, so after you've done an update you can switch cards all you like. The only think to note is that some things for the OS like BIOS, themes etc. Are stored on the SD card, so you might want to copy the system files from the old SD to the new.

[@manny1524]

@@RetroBreezeYT so I wouldn’t do the same process you did ? Install Onion OS then drag everything into the root of the new SD then everything would work normally? I would have to add things into BIOS? Or am I confused lol

Mine did the same with the stock SD Card (I mention this in the video). Are you using the included card? If so I'd recommend trying again with a Sandisk or Samsung card.

[@fabiotc]

Thanks for the tutorial. Question: If it's already on the last firmware version and I have a brand new SD card, which files/folders do I need to copy to the SD (apart from ".tmp_update")?

[@RetroBreezeYT]

If it's a brand new SD with nothing to copy back over, just the .tmp_update file will do!

[@pennyandrews3292]

I purchased a Miyoo Mini as a gift for a friend that I intended to be kind of a pick-up and play device. Will the SD card still fail within a few weeks of normal play regardless of whether the person does firmware upgrades or installs custom firmware, or does the stock SD card just respond badly if you add/remove a lot of files? It's just that this kind of process involved in backing up data from an SD card to a computer to put it on a new SD card will likely be way over their heads, and I am not there to help them through it. I already advised them to backup their games to their MacBook (they don't have a PC) in case the SD card fails, and they said they would, but they barely understand how to do that and I doubt they will actually bother. They picked it up and started playing, and they really love the device the way it is. That shipping with a bad SD card thing is kind of inexcusable if so, because a lot of people are not going to understand the concept of backing up an SD card and putting the contents on a new one. That kind of ruins the whole "pick-up and play" aspect for people that don't really understand computers. I have a feeling that in a month or two I am going to be dealing with them crying their device is "broken" and have to struggle to get them setup with a new SD card that has no games to start... I may need to put together a much simplified tutorial that shows people how to make a microSD card interface with a computer and how to remove/insert them from the Miyoo Mini, and then just simplify the process down to copying all the contents from the root of the old SD card to the root of the new one, and that way they can at least enjoy the device without worrying about it failing in a month...

[@RetroBreezeYT]

Unfortunately it is par for the course with Chinese devices. The SD cards included are literally bottom of the barrel. They might last forever, but more than likely they will fail eventually. My recommendation would always be to get a better SD card as quickly as possible. You could format it to FAT32 for the user, then all they need to do is drag everything from the included SD to the new one. It'll prevent disappointment down the line. I'll hopefully be uploading a video soon regarding common FAQs for this type of the device which should help new users learn a bit more!

[@pennyandrews3292]

@@RetroBreezeYT Yeah, I am thinking I will have to buy a microSD card for them, format it, and ship it to them. I might also have to get them a USB-C microSD card reader for the macBook, since the included dongle is full-sized USB and might not fit without an adapter. So that's the real pain point... if they do it themselves, they have to be sure to get microSD instead of full sized SD, and also be sure to get a microSD card reader that supports USB-C. The main thing that makes this difficult is they live so far away that all this has to be done via the Internet and postal service.

[@RetroBreezeYT]

It's a pretty good idea to get just a little familiar with this stuff anyway, and the process isn't difficult at all. You could also screen share over zoom etc.!

[@manny1524]

Out of all the videos I’ve watched this one is the most clear on everything! But it’s just missing one thing. I downloaded the roams to my computer. Some are zipped. Do I gottta unzip them before I drag them back into the new SD cars?

[@RetroBreezeYT]

Hi there! Thanks for watching and I'm glad you found it helpful. Whether you leave it zipped or not depends on the emulator/system. Check this page for a list of systems and which file types are acceptable. If it says ".zip", ".7z" etc in the extensions list then you can leave them zipped. Otherwise you'll need to unzip them.

Hey man, love your work so far! I've got a question, so I've tried both MiniUI and OnionOS, I'm having an issue getting the screen scaling correct only in OnionOS, MiniUI allows me to select "Aspect" which fills the screen with near perfect scaling but I can't find a way to get the same results in Onion. I can actually see what I'm having an issue with right at the end of your video, on the genesis games you show, there's a column of dead pixels on one side of the screen. I've tried all the settings I can think of to fix it but all to no avail. I'm curious if you know of any way to get a true fullscreen picture, without the dead bar of pixels on one of the image borders.

So i didnt end up doing anything, skipped that step, did what you said about copying system golder contents into the BIOS folder, again multiple options to “replace” “skip” and in some instances “merge” i selected “replace” for all and now thats completed absolutely no emulators show up under the consoles tab in the miyoo mini 🙈 im completely lost and have no idea how to fix this

There's no set list nor any way to find one. The SD cards included with the mini are illegally loaded with games by the sellers themselves.

Great video, but I copied over my 'saves' and 'states' files to my new SD card which now runs onion OS and cannot access the save/state from the original SD. Upon further inspection the 'states' folder on my original SD is empty although I had save/states on there, or so I thought unless these are stored elsewhere? I'm new to all of this so I don't know if I'm even describing the proper terminology, but basically is there another folder on the original SD card where a save/state might have gone if I used the functions 'menu' and 'save state' in game to save my progress? Should I try manually saving the game? It's Pokemon yellow if that's any help. Thanks! Edit: incidentally I just accidentally overwrote my main save state on my stock card so if I can't access it somewhere in my backup folder that I made during this video, it is gone. Unless there is a way to undo save states on the stock mini which I do not believe is the case.

That's odd. On the stock OS States are in the RetroArch/.retroarch/states folder 🤔 you could use the search function in your backup folder and search for the name of the ROM file. The state should be named the same.

There's no basic list. The "stock" SD card is filled with random games depending on who and where you buy it from. Never buy a version with more "storage" because its just a very bad SD card that will break quickly. Best way is to get a reliable SD card and source your own games.

You can even check the firmware version with no SD installed, it doesn't matter. It's extremely unlikely, in fact I'd say an almost impossible chance of bricking as long as you don't remove the SD or battery during the firmware update. After your firmware is updated, 0 chance of brick while installing Onion. And yes, you can copy the firmware update to a blank SD card too!

Thank you for the amazing tutorial. I have a question after I installed onion I found that there is a new firmware on the web, can you update the firmware with onion installed? Or can i use the original SD card and update with it?

[@RetroBreezeYT]

Good question. Unfortunately no new firmware has released whilst onion is a thing. I'd use a spare SD just to keep your Onion install in-tact when the time comes.

[@PencilHunter]

So with the original SD that it came with the miyoo you can update the console without bricking it and when it's done you can change the SD to use onion?

HI, it's there any way to put cheats on the game? I would like to catch shiny pokemon on my Fire Red pokemon game

[@RetroBreezeYT]

Yes it is! See here: github.com/jimgraygit/Onion/wiki/3.-FAQ-(Frequently-asked-questions)#adding-cheats-credits--erazemk

Thanks a lot!

[@patrickwall6316]

I don't see game cover images, any idea? Yet they are in the same folder as the roms consoles

[@RetroBreezeYT]

You put the cover images into the 'Imgs' folder inside each rom folder, right?

[@patrickwall6316]

@@RetroBreezeYT Thanks I had not done that so I'm doing it now, I found an image scraper and deleted the Chinese image names. Also any thoughts on separating GBC and GB easily? I understand about putting them in different folders, but it's not easy to sift through all the games manually and drag and drop :)

[@patrickwall6316]

I'll also mention that the file structure with the Miyoo mini is a bit of a mess I'm trying to make the Atari games appear and find myself going into lots of config files in the emulator section.

[@RetroBreezeYT]

hi how big memory card can be use ?

[@RetroBreezeYT]

Anything that can be formatted to FAT32. I've tried up to 128gb successfully but I really enjoy a smaller 32GB card on the miyoo mini. It's not really the best system for a massive card.

[@mashudmiah3820]

Hey if you can answer this i see you have a samsung evo 64 i was looking at the same one will i be able to format it to FAT32 ?

[@RetroBreezeYT]

Yes! Just use a program called fat32format: www.ridgecrop.co.uk/guiformat.exe

[@sparksterknight]

Do I Have to repeat all the procedures when I like to update from a older version of onion OS to the latest release? Or do I just download the newer files, place them on the root folder of the sd card and that´s it?

I have an upgrade tutorial video literally coming out within the hour!

Hey I can't get PS1 games to play. I get the can't find bios screen when I try and load them. I've looked on reddit for a fix but I can't seem to get it to work or can't figure out the steps to what the fixes are explaining on reddit I think. Did you have any problems with this?

[@RetroBreezeYT]

Probably a bad bios or it's in the wrong place!

[@notsrynot]

@@RetroBreezeYT Yea it was in the wrong place. I had it in the .retroarch folder instead of the BIOS folder on the ROOT of the SD. It's all good now. Something else I ran into that you can share with anyone that might have the same issue is with the Box Art. I followed your video and it wasn't working at first and it was all because I had a lower case "I" in Imgs folder name. Then when I would change it on the SD card it was default back to a lower case. So I had to create a folder on my desktop and drag it on to the SD card and volla it worked

[@curiouslittlemeowmeow]

hello sir, i want to ask. I tried to use a bigger sd card. After formatting to FAT32 and do all the copies to the new sd card. I put it on the device, it state that there's no game 😅 i do refresh the roms, but still shows no game. Do you know why? or did i do something wrong 🤔

[@RetroBreezeYT]

Are the ROM folders definitely named correctly? Check my boxart video for a list of common folder names

i ordered one without SD card. will its still gonna work? newbie here. please help

Yep, check out my updated beginner's guide and Onion OS guides

You can, but you'll need to remove dotfiles before you eject your SD card: lifehacker.com/delete-mac-system-files-with-dot_clean-377011

I'm trying to use an SanDisk Extreme 256gb and it's not recognizing the Onion OS file and it's not instaling, but the shitty SD Card that came with the console yes. What can I do? When I go to Device Info, it's there, recognized, 256gb, but don't install the fckn Onion OS

bro u literally broke my miyoo because of that error in the guide is there a way to redo it when ur already on onion or am i gonna have to cough up another $120 just because i didn’t read the description

[@RetroBreezeYT]

What on earth are you talking about? Just copy the bios out of the system/bios folder. It won't break anything. If you deleted the bios files, you can easily find them online. If you tell me what is actually going on with your Mini, such as an error message, I will happily assist you. Feel free to reach out on discord too.

[@allanpequet1007]

What if we don’t have the .retroarch folder?

Oh, if you're backing up the original SD and there's no RetroArch folder, just ignore it I guess!

The TRUTH HURTS folks. This has happened to me on the RG351P..... Thank God I bought square trade. And sent it back. I lost out on tax and the cost of the warranty.

[@RetroBreezeYT]

There's no in-built storage on the RG351P- there's absolutely nothing software-side you can't fix by flashing the SD Card. Unfortunately this kind of thing is just a reality with handheld devices. The actual truth is that you'll have a much better time if you learn the basics of flashing an SD card and managing a Rom library. If you become familiar with these simple tasks, you will really unlock the potential of your devices and learn more about them as you go. It's a win-win! As I've said, I have content like this coming, so keep an eye out.

[@XelaShade]

PSA: make sure to delete tmp updater from root of your SD card once the installation of OnionOS is done, this is because if you don't when you boot back up it will try to install Onion again and you might have bigger problem on your hand.

[@RetroBreezeYT]

That's absolutely not true. The tmp_update folder is a part of Onion OS and the GitHub states specifically: "Don't delete the .tmp_update folder, it is now part of the Onion installation." You may be mistaking it for the official firmware update file, which has to be deleted after updating.

[@XelaShade]

@@RetroBreezeYT oh yeah, I mixed it with stock firmware, you need to remove update file for updating stock Firmware, which you need to do if the device has old firmware before getting Onion. Thanks for pointing it out!

[@RetroBreezeYT]

@@XelaShade No worries, and thank you very much for watching :) I appreciate any and all feedback!

Not everybody knows what you do. The Mini especially has reached a broader crowd than just enthusiasts so tutorials like this can be helpful, and much better than a bricked device.
