McMurphy’s Mansion
https://www.myabandonware.com/game/mcmurphy-s-mansion-271
A puzzle solving text adventure where you go around your relative’s estate trying to uncover 12 gold bars. I have fond memories of playing this as a child with my Scottish grandmother.
Make one with a bunch of arcade buttons and an RP2040 running the GP2040 firmware:

However, having done this, you will learn NOT to cheap out on buttons. Cheap Chinese clone buttons absolutely suck. Once you buy a set of proper arcade buttons or keyboard switches, plus a bit of wire, you’ll have spent as much as the 8BitDo stick costs anyway.
