Shin Akuma as the secret last boss was always absurdly cheap, He was a secret fight for the best players in the arcade back in '94 that is why he's hard
I used to be able to beat him as Guile even on 8 (the hardest setting), it required a lot of turtling, but I could
The point is Shin Akuma is cheap no matter who your playing as because it was a bonus for the best players
I HAVE A DOUBLE DRAGON CAB IN MY KITCHEN!!!!!!
