The only controllers you can use Keranu are 3DO controllers.There is a adapter out there that lets you use Snes game pads.Look for it on ebay,as it pops up every now and then.Hori made a good arcade fighter stick in Japan,and sometimes it pops up for sale too.I hated those Capcom Soldier pads.They were awkward,but you may like them fine.
My fav game pad for the system is the FZ-10 systems game pad.Its small and comfortable,and is easy to use on Super SF 2 Turbo,Way of the Warrior,Primal Rage,Yu Yu Hakusho,Ultraman Powered,Sailor Moon,and Samurai Shodown.
You can always have someone convert a game pad over to a fighter stick.
Games wise.

Ive owned all these at one time or another,and they all were titles I really liked.There are others on the import side of things,but those were obscure items I thought were more or less cool to own,but not that fun to play as a game,like the Tarrot Card game I had.
