In the Theme Repository, clicking on the "2021 Stock by Miyoo" theme downloads a zip called Theme-OldStock.zip. But inside this zip is a folder called Theme-OnionBoy. Installing this in Onion OS gives the OnionBoy theme.

Discord conversations today around 11:30-11:40am Eastern brought up some interesting thoughts.

If OnionOS installation is as simple as placing a zip of the contents and a .sh script into .tmp_update/updater, you could reduce install complexity by automating the entire process upon boot after copying it to the SD.

It would be equally nice to zip a copy of the stock SD layout for safe keeping by the user should they ever want to revert.

Shift icons
Update config.jsons

Allows cleaner theming for future releases (copying one folder)

Downloaded correct .cht files onto SD card (RetroArch.retroarch\cheats), enabled cheat entry in quick menu, enabled and applied cheat but nothing happens even after restarting the game. Tested on PSX (Final Fantasy VII) and SNES (Breath of Fire)

Hi are you my friends
When i play pok crystal/gold/silver, the system always freezes when i shutdown the device and load the game again.
Or it goes to a gray screen or freezes on the last game frame before i quit.
I thing it may be related to these games internal clock, but i'm not sure.
any solution for this?

It would be kind of neat to have a simple MP3 player as an app, with a lockout that disabled the keys and turned off the screen but kept playing.

Poligraf regrets the removal of some standalone emulators :
" fceumm and a bump on picodrive from memory
And I think we are missing the Atari cores.
And fuse should be standalone like god intended "

OnionOS-20220121 (latest)
Miyoo-mini/20220108 (latest)

Device shuts off/crashes when quitting any application. Tested with Commander, Retroarch and even the onion manual app.
Tried starting fresh and setting up everything from stock twice, same issue.
Setup:
Format SD
Copy Miyoo 'Wildcard' folder contents
Copy 'TF card' folders from latest Miyoo update
Installed Onion as per instructions
Load roms

I copied over the "Cave Story" content download from my desktop-install of Retroarch to the rom-folger "NXENGINE".
Upon trying to launch "Doukutsu.exe" it attempts to start and then returns to the UI.

I tried several alternative versions of the game from various sources online, but none manage to launch.

2x filter affects the performance of blueMSX running Coleco games. Disabling filters yields soft pixel edges. Using the Null filter will restore the hard pixel edges without the overhead.

(if upgrading from a previous Onion build, delete all folders except BIOS, Roms and Retroarch)
I don't understand why I need to whack my imgs folder. That was a ton of work to get that right.

Could it be possible to add Amiga + Amiga CD emulation in "Emu" folder (in new folders "Emu\AMIGA" and "Emu\AMIGACD") ?
Pointing respectively on the existing roms folders "Roms\AMIGA" and "Roms\AMIGACD"
Many thanks for your great job

It appears that there is an issue in terms of configuration for the PSX core (Consoles/1194: PSX from the main menu).

In many games, controller 1 is disabled.

• For example, it is not possible to turn left or right in Ridge Racer Type 4 (E)
• Another example: the nofification "no controller 1" appears in Need For Speed - V-Rally

Workarounds but disable rumble effect:

• Put contfroller 1 as standard instead or Dualshock
• Or create another PSX_stock folder in Emu and copy here the PSX emulator from Miyoo stock firmware

I wish you a nice day

SMS is better ran with genesis_plus_gx and the crop-side-borders option. Normal2x. (Use Grid2x for GG only)

FC should have "display horizontal overscan" disabled. Normal2x gives a better result than Normal4x - it's not as pin sharp, but it doesn't corrupt 45 degree lines as badly. (Normal2x_Width is better again, but I suspect the jump from 4x to 2x_Width is more extreme than people looking for crisp LCD pixels would like)

MD. Normal2x.

PSX - disable all enhanced resolution settings as default. Device can handle PSX well, but ER is hit and miss. Better off as a default.

Arcade: Aspect Ratio = 4:3, Crop Overscan = OFF

Hey team, just a quick thought.

Currently: [start] +[select] brings up the retroarch menu. Hitting them again exits back to the main UI.

It feels a little counter intuitive if you want to tweak a setting and return to your game to check it out.

Suggested changes: set [start] + [select] to open the retroarch menu and close the menu - returning to the game. Utilise the miyoo option button to exit back to the main UI instead.

I had some isssues during install and I lost some of my EMU files. Is there any way for me to get them back? Any link or if anyone can send them to me thanks!

The latter struggles with F-Zero and Yoshis Island. The former can handle both at full speed with Normal2x

Please check out the upload. Also the retroarch theme is back to default instead of the gameboy theme.

I selected Cartridge from the apps menu, then immediately decided to swap themes instead of choosing a game. This causes a variety of issues:

First, the system thinks that changing to a new theme is the cartridge, so every time I turn the system on, it re-selects the theme, which shuts the system off again without an option to remove the cartridge. I can mash buttons right after the OS boots to escape the sequence of trying to select the cartridge, but at the end of the sequence, the system continues to press the A button on its own indefinitely (once per second, maybe more). I can remove the cartridge by navigating to a game while in this state then pressing Menu, but this introduces a new issue: games no longer boot... at all. All games crash immediately upon startup, even after resetting the system.

The only way to set everything back to normal once this happens (as far as I can tell) is to go into settings and do a factory reset. I was able to recreate all this using the described order of events, so it's not a one-time fluke.

Adding the languages from https://github.com/MiyooMini/language-pack to the next release.
There are slight adjustements for the english translation as well as the addition of a german translation as of right now.
Just copy the key.lang and key.lang.short files to miyoo/app/lang/.

Hello, thank you very much for such a great job!
I'm currently waiting for my Miyoo Mini unit, and would like to try Onion OS.

Only have one question:
Is it possible to flash back original firmware?
If something goes wrong or just for any other reason.

Thanks 👍

Some user has difficulties to understand :
5. Drag and drop your legally acquired Retroarch BIOS set to "/BIOS"
They don't know it is in .retroarch/Systems

Maybe not directly onion related, but I am somehow unable to get scummvm running.

I see there's a Beeb emulator on the Miyoo CFW page.
https://github.com/salvacam/beebem-rg350
Pretty pretty please can you have a crack at dragging this across to Onion. :)

menu+L2/R2 appears to have no effect

When I try to run Rondo of Blood or any other PC Engine CD games, the screen states "loading" and I get kicked back to the main PC Engine CD rom list.

I checked for the syscard1 through 3 bios files and all three are showing in both the SD card Bios folder and Retroarch's system folder. Additionally, I've also attempted to run the games in both bin/cue and CHD formats, but all attempts resulted in getting kicked back to the rom list screen.

Tried a clean/blank SD card AND a stock Miyoo Mini SD card update.
In either case, CP3 games attempt to load and crash back to the rom select pick-list.
Meanwhile CPS1, CPS2 etc work just fine (using the same/unified retroarch core).

Tested with both a clean/blank SD and one fba CP3 game (confirmed working on PC)
and the stock Miyoo Mini SD card (where the Onion installer self-relocated the CPS3 games
and not a single one loads. Same romset loads fine under stock firmware and core setup.

Could it be possible to add an AUDIOBOOKS (MP3 + M4A) player as an app?

Functionalities:

• One folder per audiobook because 1 book = 1 or n files
  File structure \AUDIOBOOK\BOOK1*, AUDIOBOOK\BOOK2*)
  Example of file structure:
  \AUDIOBOOK\BOOK1\position_file (txt? Json?)
  \AUDIOBOOK\BOOK1\chapter_001.mp3
  \AUDIOBOOK\BOOK1\chapter_002.mp3
  \AUDIOBOOK\BOOK1\chapter_003.mp3 <- files are read by order (chapter_001.mp3 then chapter_002.mp3, etc.)
  \AUDIOBOOK\BOOK2\position_file (txt? Json?)
  \AUDIOBOOK\BOOK2\one_file_audiobook.mp3
  \AUDIOBOOK\BOOK3\position_file (txt? Json?)
  \AUDIOBOOK\BOOK3\chapter_1.m4a
  \AUDIOBOOK\BOOK3\chapter_2.m4a

   The list of book for this example is (the book name is the folder):
   BOOK1
   BOOK2
   BOOK3
  

• Sync the last-reached location on start application (one position kept per book: cf. “position_file” above)

• 10 seconds forward button (R? or right cross pad?)

• 1 minutes forward button (R2?)

• 10 seconds backward button (L? or left cross pad?)

• 1 minutes backward button (L2?)

• Play/pause button

• "lockout that disabled the keys and turned off the screen but kept playing" (like requested by fggause for its "MP3 Player App" request)

Many thanks for your great job

When using a function such as "save state" "fast forward" "change save slot" the on screen notification does not show regardless of the Retroarch settings. I find this particularly useful when using shortcut commands in game to make sure they worked correctly.

I'm sure I read something about this somewhere, but I now can't find it, so I hope this isn't making you think RTFM....

I've invested a couple of long nights on Civilisation (SNES, taking me back to my yoof) and I'd really like to migrate the save games to Onion from the stock FW (2022) is this possible?

The last line of launch.sh from the /Emu/CPS3/ folder (the actual launch command) is commented out on the latest version of Onion:

Tested on a .chd version of Symphony Of The Night, I have been unable to save my game through traditional save rooms. After restarting the device, the 'memory card' appears empty as if playing the game for the first time.
Save states appear to be fine, so not a huge issue. I just like to feel that my progress has a hard backup.

Fallowing a YouTube guide, I was informed moving or deleting folders from the "roms" directory would remove the corresponding consoles from the console option in onion os. I relocated the folders related to systems I would not be using to a new folder in the root directory, however the systems still appear in the "consoles" option in onion os.

This might be on purpose but it looks like the expert mode mame2003plus points to the mame2003 rom folder vs the 2003plus folder.

It is not possible to use the mouse in Amiga emulators (uae distributions).
It is certainely due to the fact that uae uses analog pads to emulate mouse. But we don't have analog pad on the Miyo mini.
As the direction cross is visibly already mapped as joystick, we can perhaps imagine using using combination like start + direction cross.
But it seems not possible for the moment.

Many thanks in advance and again thank you for your great job.

Could it be possible to add a simple FLAC player as an app, with "a lockout that disabled the keys and turned off the screen but kept playing" (as requested by @fggause for its "MP3 Player App" request)

Many thanks for your great job

A suggestion, copy the OG theme in the theme folder so we don't loose it by overwriting it.

Is it possible to restore the on screen menu that comes with the stock launcher/os that's displayed with just pressing the menu button alone?

Please add color.png from stock theme to miyoo/app/skin to fix the missing color-settings icon.

Github seems to have let a ton of dummy.gitignore files everywhere, we can see them as a rom is the systems

Video settings in RA let you specifcy screen width and height but do not seem to have an affect on veritcal or horizontal games. Possible specific combination of options preventing this from working?

I've noticed that Atari Lynx games are not able to run either. Entering a game brings up a screen that states "loading." After that screen, I'm booted back to the Lynx rom list.

At the moment I'm trying to edit the Hotkeys for retroarch in the "consoles" section (sadly I really dislike the current shortcut setup) But everytime I remap them and quit out, it reverts back to how it was.

Also on the snes because you have fast forward toggle and hold, set to the same command key they cancel each other out. Nothing happens. But When I remapped the toggle to Y it worked perfectly.

.srm and .state files are currently saved in RetroArch/.retroarch/saves and RetroArch/.retroarch/states respectively, regardless of core. I think it would be helpful to keep them in either a separate root-level directory, or in their respective Roms subdirectories.

This will serve two purposes:

• Make it easier to keep saves when upgrading Onion
• Prevent problems in the event that roms from different systems have the exact same name

Could it be possible to add a simple VIDEO (multiformats) player as an app, with a lockout that disabled the keys and turned off the screen but kept playing (as requested by fggause for its "MP3 Player App" request) ?

Many thanks for your great job

It's not possible to use fast forward (menu+R2) on many games since if you hit A to mash text, this hotkey (menu+A) actives too and resets your game

blueMSX will appear to be stuck on an error screen when running Coleco games stating you need to power the console down before inserting a cartridge. This error screen will remain no matter what games are launched. It’s simply showing a resumed save state that is misleading. Modifying the configs and restarting the game will exit this screen.

Headphone volume is very low. If I crank the volume knob to max it gives what I'd call medium/low volume.
