Fight as Akuma:
Select the "Game Speed" then choose the "Super
X" character type on the character screen. Then highlight
the following characters in order: Ryu for two seconds, T. Hawk
for two seconds, Guile for two seconds, Cammy for two seconds,
and Ryu again for two seconds. Immediately press Start
followed by Three Punches (you can set then to one button,
such as L1). Note: The time that the pointer highlights
a character must be exactly two seconds.

Alternately, to get to Akuma easier, you will need a second controller
and good fighting skills. Go into arcade mode. Select your best
fighter. When the first fight has started, press Start
on controller two before the Cpu hits you. On controller two,
select the fighter you are up against. Then, have player one defeat
player two with a perfect score. Once defeated, you will move
onto the next round. Repeat this tactic until you reach M. Bison,
getting perfect scores every time. When you reach M. Bison, the
usual "Round 1 Fight" will happen, but you will not
fight M. Bison himself. Instead, you will fight a much harder
Akuma.
