The Staff Credits game -
The option to select the STAFF button on the options menu becomes
accessible after playing through & beating every stage in Quest mode. It
doesn't matter if you score a gold, silver, or bronze metal on the
stages. All you have to do is manage to beat them all.
After completing
the final boss in Quest mode, the game will make you play the Staff game
once, then once it's done, you'll be able to access it and re-play it
anytime you want!
