6 buttons game question

[wilykat]

Of all the game that supports 6 button mode, would any of them benefit from rapid fire option on III, IV, V, or VI?

I have a Genesis clone controller that has 6 switches for auto fire and I was going to hack it into 6 buttons PCE controller (IC replacement, rewiring, and all) and I just wondered if I should make all 6 buttons have auto fire or leave it to I and II only.

It's useful for SF2 moves like Chun Li's kick and E. Honda's Hundred-Hand Slap.

Auto fire is also useful for fire-roasting the extra-tasty thigh in Colonel Sander's Chicken Chomp.  Option III is good for the swift Finger Lick.
