Okay, rules I would put down would be.
2/3 games, double elimination
Necos are not banned (Why would they be, also remember to have NAC unlocked in case someone wants to use him)
Able to switch characters if lose, if win keep same.
Default time settings/damage scaling
Also PS2 is obsolete (Speed is way too fast, lack of playable White Len, move properties changed, move buffer is more frames iirc.)
