Gaming

If you only play old games for story mode, the CPU read inputs so you are gonna have a bad time anyway if you don't exploit their tendencies. Don't spam fire ball cause I think by the 2nd or 3rd match you start to getting jumped on. In fact, if you know how to do anti air(couch heavy punch from Ken) with proper timing you can beat the run pretty easily except char with command grab.

Like for CPU don't even try complex input, read on internet for most basic punish(like empty jump in and then throw against zoner) cause throw is really high damage & strong in SF2. If you push them to wall then you do the light punch fireball with some distance to bait them to jump over then do your punish.
