I have now ported the #Stage, a Tile and Sprite Engine to CircuitPython's 4.0 displayio system, so now it runs on any of the Adafruit boards. Here is the Jumper Wire example game running on the PyBadge:
The screen on the PyBadge is a bit larger, so you can see a bit of trash on the right hand side of the screen. If the game was written for a bigger screen, it wouldn't be there.
Unfortunately the Stage library is sensitive to how the MADCTL register of the display is set, as it doesn't do rotation in software. That means I had to modify the initialization code on the pybadge, to make it fit what ugame does. Fortunately displayio doesn't care, as it does have software rotation, so the two could be brought in sync.
The sound on the prototype of PyBadge I have is pretty bad, so I have sound disabled in this demo. Hopefully the final version will be better.
