[@dadou193]

How long did it take you from start to finish? Curious. I a am newb

[@PhyrexTechs]

It takes about 10 - 15 min. Most of that is waiting for the transferring of files to the SD card or Onion OS install process. Might take longer if you have a lot of roms to move over.

Probably too short for a video and want to avoid showing people how to download roms. However If you Google it you should be able to find the archive. org link for it. From there you just want to click the link on the right called zip. Then depending on how large your SD card is pick the option you want to download and then drag all the files onto your SD card after you have finished the onion installation. Hope that helps. If not, feel free to ask any questions.

@@PhyrexTechs Coming back to this since you're clearly pretty experienced with this stuff, I've just been made aware of something called a VNC server and that it can be used to stream my game from the miyoo onto my pc. But for the life of me I haven't been able to figure out how to get it to work. Do you have a video on this? Or would you mind providing me with some insight if not?

[@PhyrexTechs]

From what I could find about using VNC Server for this device, it would not be something you would want to use as a stream option for any type of gaming and mainly used for sharing demos or tutorials as it get 10-20 fps and costs a lot of CPU power.

Best guide ever ! Just a small suggestion, please also post or mention where we can get a ROM collection. I had to search the web for a couple of minutes before finding some archive ROM collections. Keep up the good work !

[@toycoma98]

You have to enable the power button single press to standby, just like it was when it was stock. Long press is shut down.

[@PhyrexTechs]

You can change what the single press power button does. It is located under Apps > Tweaks > Button Shortcuts. Then the setting "Power single press" can be changed from Standby to Shutdown depending on what you want it to do. I like it set to Shutdown.

[@toycoma98]

[@QueakScope]

Getting mine in the mail soon. Looks like an amazing guide to follow! My questions would be what is a good but inexpensive SD card to buy to replace the bad quality one that comes with the device initially? And how can I find all the ROMs for the Pokemon games and other games that I want to get & play? Is there an easy way to just trasnfer all the games/ROMs that come on the initial bad quality SD when purchasing?

[@PhyrexTechs]

I have some links to SD cards in the description of the video you can check out. I would recommend what ever has the best sale or is the cheapest. I also have a video where I go over finding roms kzbin.info/www/bejne/hpSze2aea7J8nqM. You can copy over the Roms and Bios from the Stock SD card (locations shown in video description) by just moving the folders to you computer then moving them onto the new SD card after installing Onion OS.

[@KuhDoda]

I lost everything bc I forgot to backup. I didn’t read the description:/ Anyway I found the ROMS and BIOS online and bc of this video, I’m back in business with the newest OOS. Thanks man

[@KuhDoda]

If this happens to you and you need to find the games again, just google Tiny Best Set and there will be guides and links to download! Godspeed

Where did you find the roms and bios I did the same thing

[@jaymcgheeb8476]

Excellent step by step guide. One question, after you've done the Onion OS install, how easy is it to go back to Miyoo's OS? Is it just reinstalling the old SD card? I'm assuming it's more involved than that.

[@PhyrexTechs]

If you installed Onion OS on a new SD card, You are right to go back to the Stock OS all you have to do is insert the Stock SD card. If you installed Onion OS on the Stock card you will then have to reinstall the Stock OS from a backup.

[@moztheravensfan]

Nice guide, thank you!

[@PhyrexTechs]

Glad you enjoyed it! Thanks for watching.

[@ultimatebreak827]

thanks it was in a loop, this is a lot better.

[@PhyrexTechs]

You're welcome

[@PhyrexTechs]

*WARNING* Back up Roms folder and bios(/Retroarch/.retroarch/system) from stock SD card if you are going to use it for this install. If you don't do this you will lose the Roms that came with the device. If you lost or need a copy of the Stock SD card search "Miyoo Mini Plus Stock SD card" on Internet Archive to find backups people have uploaded. Update: Onion OS 4.2.3 recently came out and I would suggest using that one as of now. In the future download the latest version or if you already have it installed you can use the OTA update app on the device to update it. If you need help with the OTA update I have a video walking through the process.

[@yoshsuperstar]

Thank you so much, perfect tutorial I backed up my bios and roms before install onion os, I'm super happy with this OS

[@PhyrexTechs]

Awesome! Glad you are liking it. It really is a great OS.

[@endermouse8094]

@@PhyrexTechs At the start, did you just plug in the named sd card so it picked up the miyoo mini plus folders and they would be accessible in the folders?

[@endermouse8094]

@@PhyrexTechs Just asking because im a HUGE beginner (literally knows next to nothing about this)

[@PhyrexTechs]

@endermouse8094 Yeah, you will need to put the SD card into an SD card reader. If you are going to install onion OS on the stock SD card you can pull the roms and bios from the card to your computer before formatting it. If you are going to install Onion OS on another SD card (not the stock SD card) you can pull the roms and bios from the stock card then take it out of the reader and put the other SD card in format it and add the roms to that one after installing onion OS. I hope this answers your question. If not please let me know.

[@kyo3124]

Just getting a miyoo mini plus today. Should I replace the version in your video to the most recent version of onion os? I see version 4.2.3 just dropped probably a couple weeks after you made this video. Or should I just use the 4.2 that you recommended?

[@PhyrexTechs]

You can go ahead and use the updated version. It works great.

Hey sorry! don't know how this comment got past me. I'm not to knowledgeable on the cheats side of things but it's something I will look into.

[@germanstelmakhovich2069]

Does this offer any preview of the actual games ? Or any of this systems... Ive noticed that powkiddy offers a brief video of each one while scrolling the library however my Miyoo does only show the Game box which sometimes is not very helpfull since you have 3000 games and no clue of what is what.

[@PhyrexTechs]

That is a cool feature, but the Miyoo does not support it that I know of. I tend to only have a small list of roms and add more as I need to not have that overwhelming big list.

[@Enterprisingengine93]

When you add more games, does it delete your save files?

[@PhyrexTechs]

You save files are stored in the Saves/Current profile folder. So unless you are editing that folder or changing the names of your games you should not have any issues. If you do change the name of your games you will have to make sure the save file is the same name as your rom name.

Hello friend. This is really awesome! Appreciate the work you did for this video. I get my Miyoo Mini + tomorrow and plan on using this guide. One question for a noob like me: I plan on adding the Done Set of ROMS (you can find them on the Miyoo subreddit), would you be able to make a tutorial for it? If not it's ok, Ive read the directions and they seem straightforward however the instructions say to unzip entire large folders of ROMs and other sruff straight to the root of the memory card. Will the ROMs somehow put themselves into the correct folder? That part confuses me a bit. Thanks!

[@PhyrexTechs]

Thanks! I have not tried the Done Set yet, but I have heard good things. If it is setup anything like the Tiny best Set Go then it would be organized into folders that can be dragged and dropped into the root folder. I also have heard good things about the auto setup for the Done Set. github.com/doakyz/done-set-auto-setup If you try it out let me know how it goes. I do plan on making videos for both of these sets in the future however with your device coming tomorrow that won't great help to you. Good luck and let me know if you run into any issue and need help.

[@redfoot2]

@PhyrexTechs awesome thanks man! I'm going to do my best, hopefully don't brick my device. I'm confident about the onion OS installation because of your video, we'll see how everything else goes lol I'll let you know!

[@PhyrexTechs]

What's great is that because everything installs on the SD card it's very forgiving. The chance of bricking a device is extremely low, almost impossible. If you mess something up you can format your SD card and start over.

[@redfoot2]

​@PhyrexTechs hey man, everything worked great! I'm currently playing Pokémon Unbound. I followed your video guide then just manually extracted zip files of the Done Set to the root of my SD card and voila! All good. Thanks again for your very helpful installation guide!

Can I just format the card through disk utility on Mac or do I need rufus. I’m sure disk utility on Mac has fat32 what other changes would I need

Yeah if you are on Mac you can just use disk utilities. Set Format › MS-DOS (FAT) Set Scheme (if it exists) › Master Boot Record and you should be good.

[@Saitamacz34]

Hello, did you back up the Roms from the original MM+ prior to any step shown here? If yes, do I simply need to copy the original Roms folder onto my PC before making the software upgrade to Onion, or do I need to back up all the orginal folders? Sorry, I feel like every one got it but me :) Starting at 2:35 from your video you're dropping files from your PC to the MM+. What is the PC folder where you get the files from, is that a back up you made earlier? Thanks for vid! Much appreciated

[@PhyrexTechs]

Yeah, you will just need to back up the roms folder from the stock SD card if you are going to use that one. It's recommended to use a separate SD card so I think most people are doing that.

Yeah the 2 main folders you want to back up are : Roms location = SD Card/Roms Bios location = SD Card/retroarch/.retroarch/system You can also back up the whole thing if you want to be able to go back to the stock OS. Just a fair warning that the stock SD cards are not great quality and might fail at some point.

[@Austinredstoner]

Once you install Onion OS is there anyway to go back to stock firmware that came with the device?

[@PhyrexTechs]

If you still have the stock SD card you can just put that back in. If you installed Onion OS on the stock card then the only way to get back, that I know of, is to download a copy of the stock. You can find a copy by searching Miyoo Mini Plus stock SD card of Internet Archive

[@jackbass898rb2]

Great tutorial and got Union OS installed. Just one question, where did you find the roms? Both Folders are emty of roms.

[@jackbass898rb2]

Not sure if something got corrupted and doubt I deleted them because I never touched the folder.

[@PhyrexTechs]

If you did not back up the roms from the stock SD card. You will need to acquire them again. On Internet Archive, you can find backups of the stock SD card if you want that or find a collection like Tiny Best Set Go. I also discuss this topic in my video called where to find roms and bios.

[@dadou193]

How long does it take for a newb who is not very tech savy? And then to download quality rooms and set them up nicely, how long does that take ?

[@PhyrexTechs]

That will be hard for me to answer. If you feel comfortable with all the steps in the video, it should take about 15 min. If you are a little unsure about things It might take 30 min. Maybe someone else might be able to give you a better answer on how long it took them.

[@LuisGonzalez-dbz]

This guy is the goat!!!!

[@PhyrexTechs]

[@JBqui08]

If where I buy it from it doesn't include any SD card, I just format a new branded one and add the Onion OS then roms of my own collection to it and put it in the device right?

Yup that is it! Honestly that is the best way to do it.

[@too_savage8016]

Do I have to do this a second time for another sd card or will the same onion download work?

[@PhyrexTechs]

Because onion OS is installed on the SD card. You have to do this for any SD card that you want to use OnionOS on.

im so confused. i got a brand new empty SD card and put the onion file on there but when i plug it into my miyoo it turns on like normal without downloading the onion. Ive been trying to figure it out all day now

[@PhyrexTechs]

Make sure you formatted the SD card as Fat32. Double check the folders you added to the SD card and make sure that the .tmp_update folder is showing. If you are missing the .tmp_update folder you will have to enable "show hidden folders" in your computer OS to see it

[@joshuagarza9988]

So for some reason when I reinsert the sd card it just boots up regularly. I found the one hidden file, but it's not workin. Please help!

[@Catluvr28]

I have a question, if you used a new micro sd card could you put the old one back in and still save your progress?

[@PhyrexTechs]

If you use a new SD card. You can switch back to the stock one if you want to go back to the stock OS. If you want, you can move the save games from either card to the other one whenever you like. Save states are another story cause they are only compatible with the same emulator/core.

[@arey256]

If I just got my miyo mini plus and it’s got the stock firmware do I need to do anything else before I do this? Or I can just go ahead and this right away without having to do anything beforehand? Thank you

[@PhyrexTechs]

A couple things you can try are: 1. Reformat card and download an older version of Onion OS like 4.2.2 or 4.2.1 and try again you can update it over wifi if it works github.com/OnionUI/Onion/releases 2. Try another SD card if you have one to make sure there is not something wrong with that one. 3. Try another computer to format and unzip Onion OS into the SD card

[@itsblue0102]

Im new to all this I thought I followed all the directions to the T but when I turned my mini plus back on I had no games in it. What did I do wrong?

[@PhyrexTechs]

If you used the stock SD card and didn't copy your games off of it, you will need to replace them. I recommend searching for Tiny Best Set Go for a complete collection pack. Or you can find people have made back ups of the stock SD card on Internet archive.

[@IVAN2233]

if I ever want to change to a different Bigger SD card can I just copy paste the files to the new SD card or how would that work?

[@PhyrexTechs]

That would be an option as I have done it. It just might take a long time depending on the speed of the SD card and the card reader. The other option is to just install Onion OS from scratch and then move just the roms over again.

Im not that good with theses kind on tech stuff, im having problems with the roms part. I got onion installed on the mm+, but the consoles show no games... it just says empty. How do I add the games?

[@PhyrexTechs]

Did you put them in the roms folders after the onion OS install? If you did that hit the select button and refresh roms when at the console screen. If not you will need to put the SD card back into the PC and move over your roms. If you installed Onion on a new SD card you can pull them off of the stock SD card. If you installed Onion on the stock SD card without taking any roms off of it. I highly recommend getting a rom set. You can Google "Tiny Best Set Go" and follow the setup on the Internet archive page.

[@ArjayNemis]

Hello thanks for your video. I just ordered my miyoo and the rom titles and games are all in Chinese. Im planning to install onion os and replace all the games. Do i need to copy the Bios to the new SD card?

[@PhyrexTechs]

Yeah, you will want to get a brand-name SD card if possible. Then you can install Onion OS on that. If you don't have your own bios, using the ones from the stock SD card should be fine.

[@NickyDeeVlt]

Is it necessary to format the SD card even though it's brand new?

[@PhyrexTechs]

Yeah, it needs to be formatted with the correct file system. In this case FAT32.

[@Amirichi]

Hey bro I just bought the miyoo mini plus advertised with something like 27k games.. I've never owned an after market handheld before so I never tweaked around with custom os. I'm planning on just using the out of the box os that comes installed with the mm+. If I decide to switch to onion os, will I lose all access to the roms that came pre installed on the mm+? Or can I salvage them from there to the new ssd with the onion os installed

[@PhyrexTechs]

What is really cool about how the MM+ is setup is that the OS's are just installed on the SD cards themselves. So, I would recommend getting a new SD card, installing Onion OS on it and keeping the stock card unchanged. That way you can always just swap back to the stock card and go back to the stock experience. You can copy over all or just some of the roms from the stock card to the new one with Onion OS and it will not affect the stock card. The quality of some of the roms on the stock SD card are somewhat questionable. A lot of people get community packs like Tiny Best Set: Go! that are made specifically for the MM+. Or you if you run into any issues with one you might just have to find a replacement as most of them seem ok.

[@Amirichi]

@@PhyrexTechs alright thanks so much for that. Is the quality of the stock ROMS questionable due to the stock OS perhaps? Or is it solely the result of playing the stock ROMS on Onion OS? I've now seen some videos where you can copy over the roms from the original SD card that comes with the device, together with certain bios files and save states / images.

[@Amirichi]

I'm still new, it's one of those learn as you go along, but as long as I can just copy over all the roms over to the new SD with onion os, I'll work my way from there!

[@PhyrexTechs]

@@Amirichi They are only questionable because we can't know how or where the roms were sourced from. I would say most of the roms on the stock SD card should work fine but you might run into some duds.

[@PhyrexTechs]

@@Amirichi Yeah that should work fine. If you run into any issue or need help with anything just let me know.

[@GamerReyansh12]

But the miyoo mini plus comes with games pre-installed, so if i add onion os will they disappear? Some miyoo minis comes with an SD card with games

[@PhyrexTechs]

Yes, If you use the stock SD card, which is not recommended. If you choose to use the stock SD card anyways you will want to backup/copy over your ROMs and Bios from the SD card to your PC so you do not lose those games.

wait i am confused, did u format with the stock SD card or another SD card with rufus? i’m planning to use a new branded SD card, but i plugged the stock SD to my card reader first (since i assumed that’s what u did in the video). ik u said to accept the warning message but i didn’t do it cause the word ‘destroyed’ scared me 😂 i don’t want to somehow accidentally delete anything that came with the stock SD, that’s why i wanted to make sure if this was meant for the stock or not. sorry i’m a complete noob, this just flew over my head. i’m quite embarrassed asking this haha

[@PhyrexTechs]

Hey no problem! Sorry I was not more clear. You will want to do this with your new branded SD card and not the Stock SD card.

[@PokeAlan-Aristos]

Thank you!! Also where can I find the BIOS files for PS1? Thanks!

[@PhyrexTechs]

You're welcome!

[@randomweirdo3899]

Do I have to back up the BIOS and ROM before formatting the SD card and after that put the BIOS and ROM back on the SD card?

[@PhyrexTechs]

Yes, that is what you want to do.

[@melonarcotics]

I watched this but I need a tutorial or advice bc I am trying to download it currently but it won’t show Rufus and I’m thinking that is because it says download 4.2.3

[@PhyrexTechs]

4.2.3 should work fine. You will need to download Rufus separately.

[@ltkelltrainer]

This may be a dumb question but where are/when did we get the BIOS and the roms?

[@PhyrexTechs]

The locations of the Bios and Rom files on the stock SD card are listed in the video description. If you formatted the Stock SD card you can download a back up of it or a collection like Tiny Best Set Go! from Internet Archive. If you are wanting to get your own Bios/Roms I suggest checking out my Bios and Roms video.

[@sakismiou]

Nice video thank you. Where do we find games to download?

[@PhyrexTechs]

I discuss this topic in my latest video.

[@elviscastro6064]

When you copy your Roms from your old SD card Do you create a new folder onto your onion OS SD card or do you install it into the bios file????

[@PhyrexTechs]

Drag the roms folder you got from the stock SD card into the Onion OS SD card root folder and it should put all the files into the correct system folders. The bios files will need to be placed into the Bios folder on the SD card.

[@naresargsyan8917]

hey, thank you for tutorial! I have got one question, what's the reason that we cannot use SD over 128gb?

[@PhyrexTechs]

After more research and testing, that was a misunderstanding on my part. I think the max for FAT32 is 2TB however that would be overkill. So 128, 256gb would be my recommendation. 512 for the extreme library of PS1 games (300+). The only downside would be the time it takes loading the game list may increase with that many games. Thanks for asking I forgot I still had that in the description.

[@naresargsyan8917]

@PhyrexTechs thank you so much, I have empty samsung SD with 256gb, so I was wondering if there is still a need to get a new one with lower space. Can I ask one more question? I am very new in consol games, and I was wondering, which consols would you not recommend adding to miyoo Mini?

[@PhyrexTechs]

Any time! I would add any console that you are curious about, that it supports. It won't support N64 and above so you can cross those out. But everything else runs pretty well on it and is enjoyable. It's still my favorite PS1, GB, and GBC handheld at the moment.

[@whitekoala2959]

I have no idea how to do the backup, I don't even know what the bios and roms are, and my Rufus doesn't allow me to change the formatting part, I'm so lost

[@PhyrexTechs]

If you have a windows computer this is something you could try. github.com/schmurtzm/Onion-Desktop-Tools/blob/main/README.md It should be a lot easier as it is just an application that should walk you through the process.

[@mizzycreations4043]

im trying to figure out where the emulator folder is where your dragging games to the sd card

[@PhyrexTechs]

There should be a roms folder on the SD card. Within that folder there are different folders for each emulator. Make sure this is after you install onion OS by putting the Onion OS files on the SD card and then putting it in the SD card into the device where you choose what emulators you are going to use.

[@itsHangiee]

my x,y,b,a buttons do not work while playing a game in my regular miyoo mini plus. if I install the onionOS, will that resolve the button defect?

[@PhyrexTechs]

If it's a software issue it will fix the issue. However it this is a hardware issue it will not. If you have another SD card you can give it a try then always go back to the stock SD card if you need to.

[@mckaylathornton4781]

Hello. I am confused about adding the roms and bios. Where are these files coming from to go onto my sd card?

[@PhyrexTechs]

These roms and bios are either going to be from the Stock SD card or from your own collection.

[@polyrendr]

I just got my Miyoo Mini Plus and the SD card is unmounted. Should I reformat it or do I need the stock SD card to work to have access to all the games/are they redownload able after reformatting? Thanks!

[@PhyrexTechs]

It's recommended to not use the stock SD card however if you are going to try it. Make sure to back up the roms by copying the ROMs folder from the stock SD card to your computer.

[@polyrendr]

@@PhyrexTechs the SD card was showing unmounted so I lost access to all the ROMs. I used it for 5 minutes, charged it up and once I turned it back on SD card stopped working. Anyways to access all the stock files online anywhere? I’d hate to have to return it just because of the SD card, the device works perfectly otherwise. Thanks in advance for the help!

[@PhyrexTechs]

You can get a copy of the stock SD card files from Internet Archive if you just search for Stock SD card Miyoo Mini Plus. The Stock SD card are notorious for dying so I would recommend you just get a name brand one.

[@polyrendr]

@@PhyrexTechs do the stock files come with the roms?

[@PhyrexTechs]

Most SD card backups I have seen on Internet Archive are full backups of everything that was on the Stock card including ROMs unless they state otherwise.

[@lucasmontana6163]

im having trouble with rufus it keeps failing. I get the directory name is invalid and error access to the device is denied. its a brand new micro usb just purchased.

[@PhyrexTechs]

If you are using an SD card reader I would try another USB port. If that does not work try to format the SD card with the windows tool to see if you get any errors or if that work. Something else that might cause this is Microsoft Defender’s Controlled Folder Access. you can see if you can disable that temporarily and try again.

[@derekcheung3069]

Hi mate, if I want to use the default SD card that came with my miyoo, can i follow this tutorial without reformatting the SD card? or do I need to reformat the card using rufus in order to install onion?

[@PhyrexTechs]

You will need to format the card in order to install OnionOS. If you choose to do this make sure you get everything you don't want to lose off the SD card first. Like Roms and Bios files. Roms are in the Roms folder and bios are located here(/Retroarch/.retroarch/system)

[@derekcheung3069]

Thanks foe the quick reply mate. What do Bios files do? Just so I know whether I need to keep them@@PhyrexTechs

[@PhyrexTechs]

Some systems like PlayStation require a bios file to run games. So it's best to back them up and if you ever need them you will have them.

[@grayschae4761]

literally just want to play heart gold soul silver for ds games and everything else does it do that ?

[@PhyrexTechs]

The Miyoo Mini Plus is not powerful enough to run DS games. It can only really go up to PS1 games. For something like that I would recommend an Ambernic RG405 or even better if you can find a good deal on a used 2ds or 3ds. There is a way to mod the 3ds/2ds to run regular DS games and it's great because of the dual screen and you can play all the 3ds games too. Also the HShop on a modded 3ds allows you to download them all for free.

[@PhyrexTechs]

Did some more research and it seems that I was wrong that the MM+ cannot play DS games. However, it needs to be installed differently than the native emulators. Here is a guide on how to set it up. I have not done it before so if you run into issues you may want to reach out on the reddit for help. miyooguide.fireblend.com/docs/FAQ.html#nintendo-ds-emulation-with-drastic

[@matthewcantrell1489]

Im looking into mods for the Miyoo mini. What is in the usb c port under the speaker?

[@PhyrexTechs]

That is connector for a charging dock. I go over it a little here in this video: kzbin.info/www/bejne/fHyVfomkZdSkmZI

[@jonathanmorillo1438]

I'm alittle lost. Got onion installed with no problem on a new sd. But having a hard time getting the games on the new sd card. ThT emulator file is from where? The old sd card? You have to both sd cards installed to move games over to new sd? Im a noob when it comes to this

[@PhyrexTechs]

You can move files from the stock SD card to your computer then disconnect it and connect your new SD card and move the files onto it. I have the location of the bios and ROMs files for the stock SD card in the description.

[@georgechatzopoulos136]

I am not sure if my miyoo is broken but I tried with the curent onion os and the previous one, the first time after installing I only got a black screen, then I formated the card again, added the previous version of the onion and after installing it just looks same as without the onion. I am following the guide exactly, I have a new sandisk card etc and it just dopesn't want to work. Did anyone else experience the same?

[@PhyrexTechs]

Hmm, Double check that you are moving over the .temp_update folder. Some people have reported that it is hidden and they have to enable "show hidden files" to see it.

[@92bhavik]

which emulators would you say need installing from package manager or would you say all of them? Thanks.

[@PhyrexTechs]

You will want to install any of them that you plan on using. You can always go back to it from the apps section so you don't have to worry if you miss any.

[@jarvisvachon5902]

is there any rufus alternatives for a mac user?

[@PhyrexTechs]

On Mac, you can format your SD card with the built-in Disk Utilities: Open Application › Utilities › Disk Utilities From the sidebar, select the USB drive Choose Erase from the toolbar Set Format › MS-DOS (FAT) Set Scheme (if it exists) › Master Boot Record Click Erase and wait for the process to finish

[@ejbonds8736]

Damn I can’t use Rufus because I have an old chrome book any pointers ?

[@PhyrexTechs]

You can try the built in chromebook formatting tool. I have not tested it, I'm so not sure it would work. But I think you just open the files app> then right click the SD card> select format device >then see if there is an option for FAT32

[@chillvillmancuecas6513]

Not sure if this is fixable but I got the handheld an not even 5 minutes I ran into problems were when I close a game it locks up and now majority of my roms are empty all I can play is genesis and other random games but gba ps1 all the stuff I want is gone anyone have this happen?

[@PhyrexTechs]

If you are using the SD card that comes with the device it's not unheard of. I would recommend checking the SD card on a computer to see if it asks to repair it. If that does not work you will either want to get a new SD card or try to install onion OS on it and see if it works after that.

[@gustavvson]

I turned on my Miyoo Mini Plus and it stayed on the boot screen and would not progress any further. The buttons would not respond either are there any solutions or software to solve the problem?

[@PhyrexTechs]

If you take the SD card out does it boot?

[@faekri]

After doing this will we able to finally do in game save for pokemon?

[@PhyrexTechs]

Not sure if Onion OS will fix this exact issue. From my understanding, this is an issue with either the Stock SD card or the Stock Roms that come with the device. You will either want to replace the Stock SD card with a name brand one.Replace the stock Pokemon Roms with your own Roms. Or both for good measure. You could still give it a try to see if it works just make sure to back up any roms and bios files on the stock SD if you are going to use that one.

[@robertdaone]

Does Onion OS improve performance of the device or just add some new features?

[@PhyrexTechs]

If there are any performance improvements they are negligible. The best feature hands down is the game switcher. It utilizes auto save and load states that allow you to switch back and forth between any game quickly almost like alt tabbing between games. Another great thing is when you turn the device off it will save the state and load state when powered back on.

[@suhtangwong]

​@@PhyrexTechswhat if you didn't want it to save and just wanted to turn off device?

[@PhyrexTechs]

@@suhtangwong So by default when powered off or closing a game it makes a save state incrementally this is what allows the game switcher to work and should not interfere with your manual save states. If you don't like this feature, you can disable it by going to: Apps > RetroArch Settings > Settings > Saving > Turn off "auto save state" and "load state automatically." Back out to the "Settings" menu of Retroarch, then go down to Configuration File > Save Current Configuration. And if you want the MM+ to start at the main menu on every boot: Then go to Apps > Tweaks > System > Startup... and turn off Auto-resume last game.

[@dear_nhi]

i missed the step and didn’t backup anything so the roms got deleted. how do i get all of them back?

[@PhyrexTechs]

Your best option is to go to Internet Archive and search Miyoo Mini Plus SD card and download one of the backups people have made.

[@miawalthour7330]

Please, I need help on the part where you add Roms to the SD card; I thought I followed each step closely- I see you're adding Roms, but I don't know which folder you pulled up? Is it the unzipped Onion v4.3.0?? Because I opened that folder and I couldn't find where the games were that are showing on your screen. Help appreciated, thanks.

[@PhyrexTechs]

The ROMs will come from either the stock SD card or your own collection. If you don't have your own or already wiped the stock SD card you can search for "tiny best set go" or download a back up of the stock card by searching "Miyoo Mini Plus stock SD card on Internet Archive

[@yourusernamesucks]

I have installed all the files on the SD and Onion pops up and the systems are on there, but no games. What did I do wrong?

[@PhyrexTechs]

You will need to copy the roms/bios from the Stock SD card. If you are using the stock SD card you can look online for either a digital copy of the SD card or look into something like Tiny Best Set go.

Can you explain the ps1 bios part please? Once you put the sd card back in the computer the second time, where do you go to find the bios to copy in the ps1 folder?

I'm good. unless someone here could tell me step by step, this video literally got me confused and stuck. after downloading I couldn't extract and nothing was happening In my miyoo.

[@PhyrexTechs]

You should be able to download the Onion OS 4.3 .zip file from the Onion OS website. Some Mac systems will auto unzip files and you will then just get a folder or if you did get a zip file, double click it and your Mac will unzip it. You then will need to format the drive Open Application › Utilities › Disk Utilities From the sidebar, select the USB drive Choose Erase from the toolbar Set Format › MS-DOS (FAT) Set Scheme (if it exists) › Master Boot Record Click Erase and wait for the process to finish After that drag over all the files from the Onion OS folder to the SD card. Make sure you see one called .temp_update. if you don't, Press Command + Shift + . (period) to show hidden files. Then place the card into your Miyoo Mini and it should start the Onion OS install.

There is nothing necessarily wrong with it. If it works for you and enjoy it that is fine. However, Onion OS adds a lot of features that are amazing. Things like game switcher or adding ports. A full list can be found here: onionui.github.io/
