I don't need the PCE version.
Oh, you need it...NEED IT!
Don't worry, any lot buy of hu's will have SF2 and a few Peach boys along with a few F1 Circus looseys.
But to answer your Q, the run button acts as jab(short) and you switch from between punches nad kics using the select button. It's the same setup for Fighting Street IIRC.
[edit, dolp...Nec beat me to the PUNCH!]
