I just beat Ryu 5 min ago and now I'm stuck because I saved my game at a checkpoint but everytime I hit 'R' i die instantly bc theres an enemy flying into the screen. I have tried to edit my save file with this http://punkrockhacker.blogspot.com/2014/10/hacking-i-wanna-be-boshy-game-saves.html

but I dont understand how to do it. Please help. :)
