... where does Dragonball use the Mode button? I've never heard of that.
It's the "run" button. No need to tap the direction twice with it.

Oh, fuck you.

Nightmare Circus does; Sik can tell you more.
No, I don't, never played it, just saw playthroughs (though I recall the game having full 6-pad support anyways). Though that may be the game using the Mode button as part of a cheat.

Also, wasn't it needed for SMS games?
Um, no? The 3-pad itself was designed to be compatible with the SMS controller, after all, and the 6-pad is backwards compatible with the 3-pad, so in turn it's also compatible with the SMS. Though some SMS games fail to work properly even with the 3-pad, in which case you're screwed pretty much.
Back on-topic: Shadow Squadron uses it to switch between first and third person camera. Metal Head also switches the camera with it. UMK3 seems to respond to the Mode button in menus, but it does nothing in gameplay.
