This discussion was created from the release Onion V4.2.0-beta-dev.

[Ttch21]

Sorry if this is a dumb question, I have a previous build of 4.2 installed right now, is it possible to do the MMP firmware update to enable wifi while that is installed or do I need to do a clean install of the stock OS first, do the firmware update and then install this public beta of Onion?

[Aemiii91]

Try a smaller card, or try moving all your files into a single subfolder on the card (then move them back out when finished)

[Ttch21]

Unfortunately I don't have any other microsd cards right now, but I tried moving everything into a subfolder. It reinstalled the stock OS but my firmware version hasn't changed.

Thanks for the help, I don't really plan on using the wifi anyway so it's not too much of a problem for now I guess

[tdimaggio]

Small SD card does the trick...tried with 64gb and it didn't work. Swapped to a 16GB and it worked.

[Ttch21]

Yup, went out and bought a smaller card, it instantly updated. 128GB was my original, that didn't work. 4GB worked for me.

[kyaroru]

For those who are using 128gb or 64gb sd card (which is me), we can actually Press & Hold the menu button while booting up the miyoo mini then it will go straight into Super Upgrade with a rocket icon xD

Just upgraded to 20230505 firmware yesterday for both of my MMP using 64 and 128gb sd card

[amudary]

does anybody know the username and password for ftp server? also what does connection look like for http file server? does it use any port? I couldn't connect to any of these.

[amudary]

ok figured it out.... username: root and there is no password,

[arsophan]

HTTP: root/no password
FTP: anonymous

[birby0]

I could not for the life of me get my core overrides to work. It would save aspect ratio settings fine, but would not save input settings across games using the same core or just would not save the settings at all. I set R2 to toggle fast forward, saved the override, tried it in game after and it would only let me hold to fast forward. It also kept resetting the notification settings even after turning them off multiple times. Everywhere I've looked just says to save the core override. What am I doing wrong?

[Ahotoxin]

I had a similar issue where if I disabled auto save and auto load save states it would reset the aspect ratio to stretched and vice versa. What worked for me was deleting the config file and then saving the overrides. This was on the default GB/GBC/GBA cores so not sure if it will work for other cores as I haven't checked

[jbenak]

fixed* my roms arent showing up in the games list after installing onion and refreshing. i can only run them through retroarch.

[Aemiii91]

Which roms/system? Did you follow the Emulators wiki page?

[jbenak]

all systems. i just renamed the folder to romsbk, let onion create a default empty roms folder, and copied all my roms back into that.. didnt help.

[jbenak]

yes, i double checked im following the wiki. thanks for the quick response.

[jbenak]

i was using the cheapo 128microsd that came w my mmp from keepretro.
bought a 512samsung evo select today, and that works fine.
but, if it helps anyone, i tried the newer Onion-v4.2.0-beta-dev-0763d40 on the cheapo sd, and that is also working now. problem solved. great job guys!

[G7200]

Thanks for the amazing beta version. I already dig it a lot. Is the expert mode only reachable within the Apps section? I have seen a video where the expert mode is directly reachable from the front gui menu:
https://www.reddit.com/r/MiyooMini/comments/11kvd18/advancemenu_advancemame_for_miyoo_mini/?utm_source=share&utm_medium=web2x&context=3

Thanks for your hard work!

[Aemiii91]

Yes, you can enable the Expert tab in Apps -> Tweaks -> User interface

[G7200]

Wow, I missed that option then, thanks for your very quick reply!

[AdmiralGonzoIII]

No ' or ? character available in password section for WiFi. Perhaps I am missing something?

[BKBN20]

Expanding the list of special characters will be necessary to help people who require them as part of their wifi passwords.

[Aemiii91]

Yes, we're currently using Miyoo's closed source frontend's Wifi menu. This will likely change before going out of beta, and we'll have our own wifi menu using our own keyboard (the one you see in search).

[Wilk19]

Also I found out that if your SSID has any special characters in it then you can't connect to it. My home wifi has an apostrophe in the SSID name (password is just text and numbers). I created a mobile hotspot without any special characters in the name and was able to connect to that but when I added an apostrophe to the SSID I got the same error.

[therealdickieadams]

@AdmiralGonzoIII There is a workaround to manually add the password with special characters by editing the /appconfigs/wpa_supplicant.conf file.

[Mortimus]

Do I have to do something extra to unlock RetroAchievements? I have my username/password set, and it logs in correctly, and when I load a rom like Donkey Kong Country it realizes how many achievements are available, but when I complete an achievement it doesn't register.

[Aemiii91]

Which platform?

[Mortimus]

super nintendo. I tried Donkey Kong Country, and Kirby's Dream Course

[hermitek]

The default SNES core (Beetle Supafaust) isn't supported by Retroachievements, you have to use different one.

[Mortimus]

using snes9x core worked. So hermitek is correct as to what the issue is. Is there a way to set a different core as "default"?

[tdimaggio]

Apologies in advance is this is a noob question. Not new to handhelds or emulators, just the Miyoo line in general. What's the best method to start a fresh SD card (no roms) Do I need the original Miyoo OS image? I initially tried copying 4.2 to a clean card but it didn't boot to the OnionOS installer, just the stock OS. When I copied the OnionOS beta files to my existing card it worked but I'd like to start with a clean SD and tweak my ROM files. Thanks!

[Aemiii91]

https://github.com/OnionUI/Onion/wiki/Installation#installing-on-an-empty-sd-card

[tdimaggio]

I followed those and it didn't boot to install, just Miyoo OS.

[Aemiii91]

Did you format the card correctly?

[tdimaggio]

Nope! Re-formatted with Rufus and it worked like a charm! Thanks for the assistance!

[davidzhao98]

This doesn't really affect the experience of using the beta but I noticed that upon applying a new theme or opening and closing the theme switcher, there is now an "Activity" label at the top of the MainUI instead of the usual miyoo-topbar.png. This label seems to disappear only if I open the GameSwitcher and then go back to the MainUI, or if I reboot the device.

[davidcsz]

Noticed some slight choppiness (fps) in Pokemon Emerald (mGBA). Unsure if it's related to any changes within 4.20, but definitely noticeable. I tried removing filters to see if it helped, but the choppiness is still there.

[thepailking]

Unable to connect to WiFi network when password includes "&" character.

[XK9274]

Very weird, both of these scripts work flawlessly for me and I have an oddly named wifi. Does the Orbi need to be given a WPS pin?

[devilsangel360live]

Not that I am aware of. Thanks for your help though. I'll wait for the keyboard to come through and see if that solves. But, yes it is weird!

[therealdickieadams]

It's probably not your password. I just spun up a temp wifi hotspot with an SSID of "BM0" a password of "Miyoo2023$" and the MM+ connected to it without any issue.

[devilsangel360live]

It's something to do with the network then. I will see if I can get a cheap extender and configure it for a separate network

[devilsangel360live]

Yes you both are right. I spun my mobile hotspot and it could connect. It's my network

[escenkay]

Hello,

Just updated via OTA and was stuck on the boot screen. Did a battery pull and rebooted and it seems the update is applying now.

[chrisfanwj]

Dear onion team,could you please add an option: press menu button in game = pop up the retroacrh menu?
the user experience of gameswither menu is not suitable for user like me, it doesn't content any useful funtion like saving, loading, or auto saving when quit. which means if you use this menu to quit it won't save, and thers is no button to save in this menu.... I want the original menu button back...
one more buggy thing about this gameswitcher menu: when you pressing menu in game to call it up, pressing B should maens cancel and resume to game, but it means quitting the game (and it won't save)...

[chrisfanwj]

I think after all that “menu button" means poping up a menu every time you pressing it (common mind logic), so where is that menu...
and in ffplay, when you try to change the brightness level by using menu+volume, the video has already been quitted.... why it can't be set as poping up a menu which contains "quit" , instead of quitting, come on that's a MENU button.

[davidzhao98]

That's strange. For me, leaving a game using the menu button has always saved the state the game was in, and selecting the game again from the gameswitcher loads that same state

[chrisfanwj]

right, anyway i don't want that menu button changed into a gameswith button which the function i don't need at all. thank you buddy.

[hermitek]

Switching to gameswitch should automatically save your game state (unless you have enabled achievements with hardcore mode turned on). Also you can configure what Menu button does in Apps - Tweaks - Button shortcuts - In-game: Menu button.

[chrisfanwj]

yes, but the menu button can only be set for gameswitcher, quickswitch or nothing...... it's all about their switch thing..I don't need that switchthing , I want my menu back....

[dreams897]

I can see that this version is meant mostly for Miyoo + which I do not have, however my understanding is it's supposed to be compatible with both? Yet I am having an issue of not being able to quit retroarch and having to physically remove the battery otherwise I get a blank screen forever. I tried this version because it has some notable additions like accurate battery reads (I have a custom larger battery that has been completely inaccurate) and better volume control. Maybe someone could confirm this is supposed to work with Miyoo V2.

I almost feel like there needs to be 2 different versions offered now, one for Miyoo and one for Miyoo + as things like Wifi, etc. are irrelevant to me.

[jbenak]

i plan on keeping up with nightly installs.
after i updated from last nights build to todays, the apps tab works fine, but we are greeted with an "all options off" screen for the verified tab.
please store selected emulator info so we don't have to turn our systems back on every update.

[KenFreez]

Sadly, I did an online OTA update today, and after the update was complete none of my games would load. I have a Sandisc card. Everything was fine with my original Onion 4.2 beta build I downloaded when I first got the Miyoo Mini Plus. Everything was fine when I did the first OTA update that was available, but this latest update rendered all my games unplayable. Apparently there are no cores associated with any of my roms anymore, and Retro Arch doesn't launch either. I am super sad. I wish I didn't do the update because at least I was able to play almost all my roms before. Now nothing will play. I will have to revert to the original OS now if I want to use my Miyoo Mini Plus. :-(

[escenkay]

Performing beta update on MM+ via OTA seems broken for me.
Originally discovered issue on the beta update on 06/14/2023 where the Game Switcher button wasn't working. Then trying to run any application (Retroarch, Tweaks, etc) would try to load and then bring me back to the home screen. I performed the install manually via downloading beta ota zip and moving over the SD card (after formatting FAT32 via Rufus).

Noticed there was another beta update on 06/18/2023 so performed update via OTA and similar issues. Game Switcher button not working. Retroatch works launching from apps but the other apps do not work. Performing another manual update now.

Using a 256GB Sandisk Card.

[escenkay]

Wow never received a reply so fast :)

All good I don't mind going over this process again. Really appreciate what you guys are doing. Just wanted to report this in case other users were experiencing similar issues. Look forward to the update~

Thank you

[theisdahl]

Same problem here. I will revert two versions back and wait for a more stable version.

Keep up the good work guys 🤟

[KenFreez]

Aemiii,
Thank you so much. My whole life flashed before my eyes when I couldn’t play any of my games on my Miyoo Mini plus. I hope I’m able to update soon and it’s fixed. Thank you, thank you, thank you!!!!
😊
🙏

[Aemiii91]

Haha, I'm just the messenger this time - the fix is coming from @schmurtzm and @XK9274 ❤️

[KenFreez]

Much love ❤️ to all those working on getting Onion OS as close to perfect as possible. You all are Super Heroes. I don’t know if you guys realize how important this is to many of us. Life can be tough and sometimes down right cruel, and something that can bring someone back to their childhood to remember the good memories can be priceless during those bad times. My dad introduced me to video games when I was a young child and we gamed through good times as well as the hard times. He’s 73 years old now and we still game together. I setup his Miyoo Mini Plus (black) with Onion. I told him not to update yet. 😂
Thank you kindly gentleman. You guys will surely not loose your deserved reward for the good you’re doing for us.
🙂✌️

[Steamkraft]

new Version works for me now - Thank you alot :)

[XK9274]

This is great to hear, we've all had some pretty late evening so this one so fingers crossed it's fixed for everyone now!

[KenFreez]

Me too. I downloaded the new update last night and games are playing no problem. All is calm in the universe now. 😁

[theisdahl]

@XK9274

How would I go about trying to get the latest version via OTA - When I press the OTA menu it only comes back out to the Apps list again.
I also tried to format SD and install older 4.2 beta version but device would not boot up in firmware mode?

What are my options at this stage. Thank you.

[XK9274]

You're likely going to have to do an SD card rebuild.

If you connect your SD card to your pc and browse in you'll probably notice the folder .tmp_update is missing. (It's a hidden folder so make sure your OS has this enabled).

If it is missing you can download the new (fixed) build here:
https://github.com/OnionUI/Onion/releases/tag/latest

And follow the instructions here:

https://github.com/OnionUI/Onion/wiki/Installation

[theisdahl]

Thank you - I'm up and running and back in the game again 🙌

[Legandos]

hi all after update GBA games arent running fullscreen. how to fix this? plz help

[KenFreez]

Try looking up the hot keys for Onion OS.
To change the aspect ratio hold the option button and press start button at the same time. You should be able to toggle through all possible aspect ratios this way until you find what you like.

[KenFreez]

I tried playing my dad on his Miyoo Mini Plus a 2 player net play game. I was able to succeed on nes games, but on other platforms like SNES or NEOGEO it would not work. I noticed the host unit would show “Netplay UpNp port mapping failed.” Not sure what’s going on there but I thought I’d bring it up to the Devs attention. Thanks.

[XK9274]

Can you check the notes on this PR: #891 regarding setting your default core. You'll have to set it to a core that supports netplay while in GLO. Some cores don't.

We're going through some and testing but we could do with more people helping testing netplay ;)

There's a spreadsheet here with more info on what cores do have support:
https://docs.google.com/spreadsheets/d/1y1esG3HcNagPG8cy-ulZK_mhhUb93pqG5_XEtRRgKQ4/edit?usp=sharing

Re: the UPNP mapping error is normal as lts used for global connections & enabled in retroarch.cfg but it's a red herring and doesn't affect local netplay, it's likely a core issue.

[KenFreez]

Awesome! Thank you for that. 😎
Ok, so far, I have been able to run NES games in 2 player netplay pretty much perfectly. I got NEOGEO to work also, but it ran kind of glitchy with a lot of unsynchronized moments. I couldn’t get SNES to run. I couldn’t get NGPC to run. That’s all for now. Im going to try SEGA GENESIS and MASTER SYSTEM next. I’ll come back and let you know how that turns out. Im going to try SNES again. I want to make sure I try every core on ONION OS because I only tried the cores on the spreadsheet that were marked “yes.”
That’s all for now…

[TurboTronix]

Anyone knows why i keep getting no core found when trying to play Mario Kart with 2 miyoo on the snes emulator?

[schmurtzm]

I have created this issue on the core few time ago :
libretro/supafaust#21

You can choose chimeras snes or Snes9x 2005 by using GLO menu, it will give good performances and Netplay compatibility.

[TurboTronix]

What's the easiest way to switch the cores?

[schmurtzm]

Select your rom in the list and press Y to display GLO menu. Then from here select "Game core"
Video demo here : https://www.youtube.com/watch?v=IQQi8A6M_zw&t=1035s

[TurboTronix]

ok cool now I tried to get both myioo to have one as player 1 and the other as player 2 but for some reason when I make one host and other connect to this host, they both just show the same as if it's just a mirror image and not 2 player view.

[TurboTronix]

Ok its working! Used Snes9x 2005 as core. Had to do the following:

1. host device: start the game, start the host
2. second device: start the game after the host device is hosting it

[GaroPpo]

Sorry if my question is OOT or the wrong place. I just got my device and it came with "202303292051" Firmware. Do I Need to reinstall the firmware or install the Onion v4.2 without changing the firmware? Thanks before

[Aemiii91]

You should be good to go

[STX84]

Hi, thanks four your hard work on OnionOS for MM+, but sadly few last beta releases are just broken for me. It all started with the use of updates via OTA. Now even when I do a clean install via SD card, some games that are important to me still don't work. I know one version worked very well for me (before using OTA) but I can't seem to find it anywhere to download. This is version 072c73c. Can I download it from somewhere? I would be grateful for help.

[Aemiii91]

What's not working?

[STX84]

As far as games are concerned, Fire Emblem: Mystery of the Emblem for SNES (with translation installed) has stopped working and Demons Crest for SNES. The menu button doesn't work either, the achievements in the Retroarch menu are gone and everything is so "unstable". Sometimes it works, sometimes it doesn't. I can't enable OTA anymore either. After buying MM+, I uploaded the 072c73c version and, interestingly, everything worked stably and I just want to go back to it. I understand this is a beta version so it's not that I'm complaining, I just want to play my favorite games :)

[omallz]

Hey team,

Appreciate all the hard work you all do to provide us with this great software.

I'm not sure if this will be one you'll want to answer, but i have two mini pluses i have been waiting to setup but i am a bit pedantic so i want to wait for the activity tracker to work first.

I have been keeping an eye on the commits, but i was hoping for a conservative estimation on when the next beta release may be out with activity tracker?

Thanks again.

[soj0]

does anyone know when the beta version for the plus will be available again

[STX84]

What is the default user and password for SSH?
root with no pass does not connect

Update:
It's onion:onion

[tGecko]

as stated here, onion:onion

[astearon]

Found it after a bit of reading the release notes of the beta, thanks!

[zazennoir]

Hi everyone, I was wondering why the version 4.2 seemed to not be downloadable anywhere? Is it not possible to get onion os on the mini plus anymore? So sad, I was hyped.

[Aemiii91]

It's right here: https://github.com/OnionUI/Onion/releases/tag/v4.2.0-rc

We're soon releasing the full V4.2 though

[TheAncientAnimal]

Hello, I just installed Onion-v4.2.0-RC-snapshot-a5064207.zip, but after installation, the Mini+ reboots and then a charging battery icon is displayed for a couple of seconds. Then it powers off. If I try to power it on, it shows the battery charging icon again and then powers off and doesn't seem to boot. Any ideas? Thanks!

[Aemiii91]

Charge it

[TheAncientAnimal]

I was expecting it to charge when connected to a computer, but looks like it needs to charge with a power adapter instead. It's booting without issues now. Thank you!

[0023-119]

Are we far from final 4.2 release? It's been quiet for quite some time now...

[XK9274]

Are we far from final 4.2 release? It's been quiet for quite some time now...

We're wrapping some things up.

Aemii has put together an incredible new website & it's currently being filled with documentation/release info by the team ready for release.

[0023-119]

Thanks for the heads up! I asked, because I also own a RG35XX and its alternative OSes seem to have stalled with develeopment for a while now after the initial burst of interest. Glad to know the 4.2 is on it's way :)

[XK9274]

No worries! Nah, Onion dev is in full swing, there's always a lot going off in the background. All the Dev team are constantly looking for new ways to improve the experience

[Allismeaningless]

I'm sure there will be a separate announcement, but just went up to 4.2.2 via OTA update on the mini plus. Worked like a dream, unending thanks to all who have contributed to the latest release.
