There is a special option that lets you pick between "Manual" and "Auto". Auto will block for you automatically for the first 9 attacks the opponent tries on you. However this was turned off in the American version, you have to turn it back on in the operator menu. The "Manual" option lacks a description too.

NOTES

-All versions of the game have a mode where you can have Ryu and Ken fighting against Bison/Vega. However, the Japanese version has an exclusive music track to this mode which is a version of "Itoshisa To Setsunasato" without lyrics. This song was first heard in Street Fighter II Movie. You can hear the Street Fighter Zero version here.
