Hi @MicroGuy,
You would not be able to easily interpret/compile MakeCode Python code into a game and run it on a RPi, since MakeCode Python is only an translation layer on top of MakeCode Static TypeScript(JavaScript), which can be run online in the simulator or compiled into executables for different supported hardware.
However, when first compiled to the supported RPi0 hardware in the editor and downloaded to .elf files, these games actually work on most ARM hardware running Linux(RPi0, 1, 2, 3, 4 etc.).
Not only on “pi0” and not requiring the “arcade pi0 os” as @robotosaurus incorrectly/inaccurately claims above.
Lacking internet access for your RPis, you could transfer the .elf game files by e.g. USB thumb drives.
