For the next two weeks, it’s BASIC Week 2 at Reddit r/retrobattlestations. You can participate with your Commodore 64 or at least play along with your favorite emulator. I’ve ported the code to the C64 and you can get the code from the thread on Reddit. Or you can download the D64 image here to make your own disk or to use with an emulator like VICE.
Have fun!
