What was the MODE button for?

Another one for the list: IMG International Tour Tennis works fine with a three-button controller or a MK-1653 six-button controller (with or without MODE). It does NOT work with my MK-1470 six-button controller, regardless of whether I hold down "MODE" or not.

(Of course, the game's completely broken to begin with, so it really doesn't matter that much.)

Wow I never knew the mode button could be used to disable 6-button mode on power up! Well I might have heard that somewhere before but thought it was incorrect. I figured people just assumed it was for 3/6 button mode. But I noticed it doesn't toggle and I figured that was what people expected. I just knew it was used in certain games as an extra button. If I remember After Burner on 32X can use it to fire a missile.

Now I wonder why Sega put a 3/6 button switch on the 6 button arcade stick if the mode button could do that. I figured you needed that switch to use it on the mentioned games like Golden Axe II. I guess it's just easier than holding down something while you turn on the Genesis.

In Wolf32X, MODE toggles the automap.

I had problems with the 6 button pad playing Castlevania Bloodlines. Had to reset and hold the mode button down to play.

Herzog Zwei would not function with any 6-button pads.
I tried everything (at least I think so) with the mode button and could not get the controller to operate properly.
Had to dig out a couple 3-button pads.

Weird, I've never seen a problem playing Castlevania Bloodlines with a 6 button controller.
