Not quite that easy. Without building and programming a new cpld file you could only swap a game that uses the same romboard originally. Most likely not a match for a less-desireable game.
Yeah that's a constraint, but fantasy zone 2 runs on a 5704 rom board, so we could just replace a specific game that uses that no?
171-5704: Bay Route, Aurail, Cotton, Wonder Boy III, Wrestle War, Tetris
Similarly destroyer from jail can be a 5704 or a 5797, so depending on which rom files we use we could also swap out one of those

Hi, isn't Fantasy Zone 2 running on System16C specifically made for this game which has more work RAM I believe?
So how would it run on a System16B? I'm confused
