Lime 7.0.0 and openfl 8.4.0 should work.
you can try this manually by installing openfl with
haxelib install openfl 8.4.0
and going in the lime directory that was cloned in my script and do a hard reset to tag 7.0.0
git reset --hard ffe75cb33c73febcd8f5ae2d016e533e01932edc; git submodule update
and then rebuild lime:
lime rebuild lime rpi
I’ll work on my setup-script next
