Play old Arcade Classics on the Teensy4.0

Very cool! Thank you for sharing this! I would like to try my hand at adding a couple games that I love, Joust and Dig Dug. Did you encounter any pitfalls during your development that would lead you to believe this would be hard or impossible? I want to avoid wasting the time if this is a road that you've already been down. If I can get those working my next step is to _try_ to port this to SAMD51.. and play on a PyGamer. Those are the only two games I like playing all the time, so I think it might just squeeze on there if they work at all in this early version of MAME. Any assistance your can offer would be most appreciated!
