Which fighting games make useful use of Start and Select/Back buttons?

With the goal of use both buttons for many FG think I will put these buttons together with the six buttons layout(vewlix at the moment). Until where I know these games make useful use of both.

Start
KoF 2k arcade: strike gauge; SFA2/3 arcade: some specials and super combos; Samurai Shodown IV, V: suicide; CvS2 some Dan moves.

Select/Back
SFIV console(PC too?) series: S/BLink; SFAA: same above.

I use my start button for pausing games. I only use back in Skullgirls and in arcade sticks that I need to use Start+Back=Home functionality. Six buttons and 4 directions. That’s all that matters.
