I loved those...There was a shady bar near my house with a SFII machine in a dark corner in which Zangief could fly through the screen throwing hadoukens with yoga flames coming out of his shins. I think that was the best version.
EDIT:J/K ofc
Mid air sonic booms
Crouching sagat tiger shots in mid air.
Mid air and electric blanka..
Yet if someone picked dhaslim and did a yoga flame the machine would reboot lol
My vote is for SNES version, sega's 6 button controller just wasn't doing it for me, and it looked nicer on SNES imo
For Xmas my dad built me an arcade cabinet, paid God knows how much for a SNES arcade stick (had an circle gate too!)
