Support Ubuntu core
Feel free to test current snap package at:
https://snapcraft.io/pinball
I suspect some issues with audio or startup, testers feedback welcome.
If you want to test on virtual machine as explained at: https://discourse.ubuntu.com/t/getting-started/19737
Then just run:
snap install --candidate mir-kiosk ; snap info mir-kiosk
snap install --edge pinball ; snap info pinball
snap list

It works using software rendering:
Mar 11 10:19:24 ubuntu pinball.daemon[2609]: Vendor : Mesa/X.org
Mar 11 10:19:24 ubuntu pinball.daemon[2609]: Renderer : llvmpipe (LLVM 11.0.0, 128 bits)
Mar 11 10:19:24 ubuntu pinball.daemon[2609]: Version : 3.1 Mesa 20.2.6
Some warnings should be investigated, though
sudo journalctl -u snap.pinball.daemon
Mar 11 10:19:22 ubuntu pinball.daemon[2604]: _XSERVTransSocketCreateListener: failed to bind listener
Mar 11 10:19:22 ubuntu pinball.daemon[2604]: Failed to initialize glamor, falling back to sw
Mar 11 10:19:25 ubuntu pinball.daemon[2609]: ALSA lib confmisc.c:767:(parse_card) cannot find card '0'
Mar 11 10:19:24 ubuntu pinball.daemon[2618]: > X11 cannot support keycodes above 255.
I also tried on RPi3 but there is a rendering issue/freeze in table modes (I suspect something odd in offscreen swap rendering)

Have you considered using stage-snaps: [mir-kiosk-x11] as described in https://ubuntu.com/tutorials/x11-kiosk?
Thanks @AlanGriffiths
Yes this works too but I wish window to be displayed fullscreen this is the reason I kept using i3 hack from
https://github.com/MirServer/xwayland-kiosk-helper/blob/master/xwayland-preload/xwayland-kiosk-launch
May this launcher be merged into:
https://github.com/MirServer/mir-kiosk-x11-snap/tree/main/env-setup/hacks
Anyway I didn't want to use X11 in the first place but wayland since this project is using SDL2 and it is working fine on ubuntu classic see this video clip on RPi3 :
https://youtu.be/4Ja4TNmBSFc?t=46
But for some reason using wayland launcher for Mir does not display anything, while log did not look suspicious, any hints welcome? (Is Mir stack supporting legacy opengl or only GLES ?)
If interested to replicate this issue I'll open a ticket and push a branch.

Yes, SDL2/Wayland works on mir-kiosk/Ubuntu Core/RPi3. See, for example, mir-kiosk-neverputt,
But for some reason using wayland launcher for Mir does not display anything, while log did not look suspicious, any hints welcome?

(Is Mir stack supporting legacy opengl or only GLES ?)
Mir is irrelevant here. The kernel graphics stack on Ubuntu Core is the same as on Ubuntu Classic. But you do need to include the Mesa userspace libraries in your snap as described in the above tutorial.
If interested to replicate this issue I'll open a ticket and push a branch.
From what you said, it seems likely the issue is in your snap.
Current snap works fine on qemu using wayland-launch
Menus are displaying fine on RPi3 (with this fullscreen option: https://github.com/adoptware/pinball/commit/23fba2b1947ac35ac1c5a4d6ed5edf14547efa7c) but play mode might suffer some locking or double buffer issues, I didn't investigate yet. But I noticed that while playing the table can be refreshed if paused and resumed (hit Esc, select play).
Note that the ubuntu classic image is working as expected on Pi3 but it uses weston compositor not Mir. it can be downloaded from https://github.com/adoptware/pinball/issues/16 Soon or later I'll trace the rendering part to compare with real x86_64 machine.
For portrait display I am tracking this Mir feature: https://github.com/MirServer/mir/pull/1643
Some updates on Pi4, it work pretty fast on default config (landscape view) it's about 40 fps with prof table. for the record:

I may try again with pi3 to understand is GPU is powerful enough
Hi, Some updates about this effort
I built a demo image (on worst table) for amd64 (it works with virtual box):
curl -O https://bashupload.com/ZLYFb/cfep0.gz#./file/pinball-table-hurd-core20-amd64-pc.img.gz
It's super easy to rebuild using this helper makefile: https://github.com/rzr/pinball-table-hurd/tree/master/snap/image
More investigations should be done for Pi3 or Pi4 (I need a UART cable to troubleshoot):
https://forum.snapcraft.io/t/built-uc20-rasperry-pi-image-hangs-on-boot/23891/19?u=rzr
BTW, I'll present those works at next LibreGraphicsMeeting 2021:
Last but not least, I proposed this as an appliance:
https://discourse.ubuntu.com/t/propose-new-appliance-emilia-pinball-pincab-profile/22214
Feedback welcome here or on fediverse: https://mastodon.social/@rzr/106210478055984663#lgm2021

I'm not sure what you mean. That PR landed last year, long before you decided to "track" it.
Yes I confirm portrait works in mir, Thanks @AlanGriffiths for that. I've been using it in "gnu" image, I'll push changes soon.
Been reported about issue with audio
may this help:
