Ok, this is gonna be quick
First, you open your fight.def
then you go down until you see this,
[Round]
match.wins = 2 ;Rounds needed to win a match
match.maxdrawgames = 1 ;Max number of drawgames allowed (-1 for infinite) *2001.11.01 NEW*
start.waittime = 30 ;Time to wait before starting intro
now where match.wins at, just change that 2 to any number you want. Now you're done. Told ya it was quick.
