mk64's game loop depends on a series of states. It runs a wide branching series of code based on these states. State 1) Clear framebuffer State 2) Run menus State 3) Process race related logic State 4) Ending sequence State 5) Credits

Note that the state doesn't flip-flop at random but is permanent until the state changes (ie. Exit menus and start a race).
