Xbox arcade stick pad. what does it work on?

I want to know if the blazblue arcade stick will work with street fighter 4? Just the street fighter stick looks like it has 8 buttons but the blazblue has 6. I'm guessing it does just the arcade stick pack (with game) is 64 on amazon so if anyone knows where there is a cheaper one link it.

Street Fighter uses 6 buttons... and the stick will work well with a lot of XBLA titles and other fighting games.
