Hi,
Just finished a work-around for running MakeCode Arcade games natively in RetroPie and from the Raspberry Pi OS text console, with keyboard and controller support for up to 2 players:
https://github.com/Vegz78/McAirpos
Not sure if this could be of interest here, meaning if it could work with/be integrated in a similar way into Recalbox?
Br,
Vegard
Managed today to run MakeCode Arcade games on Recalbox with McAirpos, with menus in EmulationStation and everything.
Still working on the the last few details:
-How to keep the game .elf files executable inside the default /recalbox/share/roms/makecode folder
-Automated installation script for McAirpos on Recalbox
-Implement and compile a few small changes required for launCharc to detect and work on Recalbox in addition to RetroPie.
Hopefully back again with good news here soon!
Hello @Vegz78
i think you need to go discord channel to ask bkg2k to help you on recalbox because, recalbox use different things to manage gamepads (configgen)

Thanks for the tip, @acris!
But since the MakeCode Arcade games use raw GPIO inputs or EV_KEY scan codes for controls, the game launcher handles gamepad detection and setup itself, via uinput-mapper and independently of Recalbox/EmulationStation.
I was positively surprised that almost everything, even the Python parts, worked out of the box on the buildroot system underlying Recalbox. Only had to remove 4 sudo commands from the source code.
However, there are, as mentioned, still some small details remaining before I can announce a viable solution for MakeCode Arcade on Recalbox, like automated installation and some work-arounds for the overlay mounted file system.
Happy to announce a working solution now!:

Only for Recalbox 7.1.1-Reloaded! on Raspberry Pi and maybe still experimental, but working on my RPi4 4GB.
Feedbacks on GitHub are very welcome!
Theme for working McAirpos solution:
Wow, impressive ! 
Happy to announce Recalbox 8-Electron support for MakeCode Arcade games, with McAirpos!:
