so what are the EX version of some of the moves?
are they like JFs for SC?
To follow what iKotomi said, they aren't like JFs in terms of input. They're done by doing the normal move input (i.e. + Punch for Fireball), but you hit two attack buttons instead of one (so to get EX Fireball, you would do + LP + MP). So there's no special timing required, but they (obviously) use up an EX meter per use.
