OG MM and Allium

[axiel7]

I'm trying to get this to work with my setup: OG Miyoo Mini with Allium

So far I only had to rename some paths and folders but now I'm getting this error at launch:

pico8_dyn: error while loading shared libraries: libfreetype.so.6: cannot open shared object file: No such file or directory

Any idea what is this lib? Maybe it's a lib that's included in Onion but not on Allium?

Hi sorry i don't have any cards with allium on atm.

You'll be using the same firmware though, so if you'll need to set your LD_LIBRARY_PATH in the launch script to include the location:

/customer/lib/libfreetype.so.6

It will look something like this:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/customer/lib

It seems I was missing the /mnt/SDCARD/miyoo folder (I think because I was in an old fw) that contains some required libs.

After upgrading the fw and putting the miyoo folder now I get another missing lib:

pico8_dyn: error while loading shared libraries: libpng16.so.16: cannot open shared object file: No such file or directory

I tried exporting /customer/lib as you said with no luck.

Has been this tested in the OG Miyoo Mini (not the plus)? I'm starting to think this is not compatible with the OG.

Works fine on the OG mini. You're missing libraries or library paths in allium.

Works fine on the OG mini

Thanks for clarifying

You're missing libraries or library paths in allium.

Does your miyoo folder contain the libpng16.so.16 lib? I tried looking for that lib in the root filesystem but I couldn't find it and the official firmware doesn't have it either.

My guess is that maybe OnionOS adds that lib and maybe others while installing?

Okay I got it working, for reference these are the steps:

1. Follow the instructions from the README.

2. Rename the /mnt/SDCARD/Apps/pico folder to /mnt/SDCARD/Apps/pico-8.pak so Allium detect it as a program.

3. Modify the file /mnt/SDCARD/Apps/pico-8.pak/script/launch.sh so it uses the new path:

   export picodir=/mnt/SDCARD/Apps/pico-8.pak

   And the mount dir at the end of the file:

   mount --bind /mnt/SDCARD/Roms/PICO /mnt/SDCARD/Apps/pico-8.pak/.lexaloffle/pico-8/carts
   start_pico
   umount /mnt/SDCARD/Apps/pico-8.pak/.lexaloffle/pico-8/carts

   Note: make sure your pico-8 roms directory is /mnt/SDCARD/Roms/PICO and the roms file extensions is .p8.png

4. Modify these two lines in /mnt/SDCARD/Apps/pico-8.pak/.lexaloffle/pico-8/config.txt so it uses the new path:

   
   // Location of pico-8's root folder
   root_path /mnt/SDCARD/Apps/pico-8.pak/.lexaloffle/

// Location of cartridge save data cdata_path /mnt/SDCARD/Apps/pico-8.pak/.lexaloffle/pico-8/cdata/

5. Put this file [libpng16.so.16](https://github.com/OnionUI/Onion/blob/main/static/packages/RApp/SCUMM%20(ScummVM%20standalone)/RApp/scummvm/libpng16.so.16) from the OnionOS ScummVM inside `/mnt/SDCARD/.tmp_update/lib`

Ah good stuff, glad you got it sorted, sorry i couldn't be more help - working long hours atm.

I think we can leave this issue open for some time as i doubt it's just you who will be trying to get this working on Allium and it's great that it will be supported on other UI.

Thanks for investigating this issue!

I have packaged the required changes here: https://github.com/goweiwen/pico-8-wrapper-miyoo/releases

Steps

1. Download and extract pico.pak.zip to /Apps.
2. Put the pico8_dyn and pico8.dat files into /Apps/pico.pak/bin (create the folder if it doesn't exist)
3. Run the Pico-8 app

If I (or anyone) have time, I will try to get this build to work with both OnionOS and Allium.
