Before I would do the following:
main loop {
Prepare screen drawing stuff
if(TITLE_SCREEN) {
    GsSort Title Screen stuff
}
elseif(GAME_SCREEN) {
    GsSort Game stuff
}
etc

if(ONE_PLAYER) {
    Proccess for 1 player
}
elseif(TWO_PLAYER) {
    Process for 2 player
}
etc

} end of loop

However, I'm wondering whether it's better to get rid of these checks
every loop by checking what screen it is first, then going into a
special loop for that screen, and doing similar for the number of
players. Do those checks cause much of a performance hit - is it worth
worrying about? Or is it better to keep the amount of code down (due
to the 2MB limit), rather than duplicating it? I suppose I could use
pointers to functions, so the main loop would be the same code, but
somewhere else changes which function is pointed to, which does the
specific proccessing. Could this be a good method?

Cheers,
Rikki
