I've been thinking for a while on programming board or other finite state games on the Pronto, like these mathcing pairs memory games or tic-tac-toe. The toll one has to pay for the total absence of computational capabilities is to build dozens or hundrends or ... of screen, covering each possible state the game could be in. The number of panels needed grows exponentially, but a memory game of matching 8 pairs should be feasible, but a memory eater.
One could also make a tic-tac-toe game on a 3x3 board, board rotations allowed to cut down panels.
I started programming the pair matching game but got really bored halfway. It however is enough to both demonstrate functionality on the emulator and guide to completion. I sent it to Cary, to see if its worth the effort to complete.
