...That's not bad who ever really did those combos without any programmable joystick or joypad with turbo buttons. In those days when street fighter 2 was out, thats the kinda combos I was doing...
Jump in fierce, or roundhouse land with a standing fierce or short and do the summer sault kick or do the sonic boom and then back slap. and lots more I use to do, now sence they brought Guile back, althought I mostly use Akuma, Ryu, Ken, Sagat, M. Bison, Zangief, and Blanka with others I sometimes use, I've lost interest to play with him, so today, I'm trying to master him again. He's an average player to me compare to my 3 best players which appearantly every1 knows, but if I had a choice to pick Guile or Charlie., I'll definitle pick Charlie. To my opinion, Charlie perform the summer sault way better then Guile.
P.S. Something fishie about that video clip, if i didn't know any better, I'll say maybe that person use Game Genie codes to do another Sonic Boom and then another and then.....
