it is possible.
you just make it that way.
you need to have every character you intend to use, all of there sprites in the SFF. you COULD palette this character and include everyones colors on the palette, or NOT which is alot easier.
So you have there sprites for the moves.
all you need to do then is just code it.
its the same way you make a character.
Do you know how to make a character?
