Pewmulator is an emulator for the PewPew library that lets you play the games writen for the PewPew devices on your computer. It comes in the form of a Python 3 library that uses PyGame under the hood to implement all necessary parts of the PewPew library.

Note that the code is then being executed with Python 3 and not CircuitPython, so there may be some differences. The most obvious difference is the amount of RAM memory available — so if you write a game in Pewmulator, chances are it won’t run on PewPew because of lack of memory.

You can get the library from the github repository. Just place the file alongside the code of your game, and run your game with Python 3.
