[Characters]
;How to add characters
;---------------------
;Use the format:
;    charname, stagefilename
;
;eg. For a player with filename "kfm",
;    and stage filename "stages/mybg.def"
;type (without the semicolon):
;    kfm, stages/mybg.def
;
;If you want to load a different def file, you can enter it
;as a directory plus the def file. This example loads up
;chars/kfm/alt-kfm.def:
;    kfm/alt-kfm.def, stages/mybg.def
;
;If you put "random" as the stagefilename, then a random stage will
;be selected for that player. eg.
;    kfm, random
;
;Zipped characters are also supported (experimental).
;Place the ZIP file in the chars/ directory. The name of the
;character's .def must match the name of the .zip. For example, if
;you have suave.def, then the zip file should be named suave.zip:
;    suave.zip, stages/mybg.def
;
;Optional parameters may follow on the same line, separated
;by commas. Each parameter has the form:
;    paramname = paramvalue
;where paramname is the name of the parameter type, and
;paramvalue is the value to assign that parameter.
;The optional parameters are:
;
; - music
;   Set the paramvalue to the name of the music file to use
;   as the BGM for that character. This overrides the bgmusic
;   parameter in the stage's .def file, so you can re-use the
;   same stage for multiple characters, but have a different
;   BGM playing for each person.
;
; - includestage
;   Set the paramvalue to 0 to avoid including this stage
;   in the stage select list (in VS, training modes, etc)
;
; - order
;   Set the paramvalue to the ordering priority to give the
;   character. Valid values are from 1 to 10. A smaller value
;   means you will fight the character sooner. You will never
;   fight an order 2 character before an order 1 character,
;   and never an order 3 character before an order 2 one.
;   For example, you might want to set your boss character
;   to have order=3. The default order value is 1 if you omit
;   this param. See *.maxmatches under [Options] for how to
;   limit the number of matches per order priority.
;
;   Some examples:
;        kfm, stages/mybg.def, includestage=0
;        kfm, stages/mybg.def, music=sound/song.mp3
;        kfm, stages/mybg.def, music=sound/song.mp3, includestage=0
;        kfm, stages/mybg.def, order=3
;
;You can also add a randomize icon to the select screen. To do
;this, put the word "randomselect" on a line of its own, with no
;extra parameters.
;
;Insert your characters below.

[Options]
;Here you set the maximum number of matches to fight before game ends
;in Arcade Mode. The first number is the number of matches against
;characters with order=1, followed by order=2 and order=3 respectively.
;For example, for 4,3,1 you will fight up to 4 randomly-picked
;characters who have order=1, followed by 3 with order=2 and 1 with
;order=3
arcade.maxmatches = 4,6,8,1,1,1,1,0,0,0

;Maximum number of matches to fight before game ends in Team Mode.
;Like arcade.maxmatches, but applies to Team Battle.
team.maxmatches = 4,6,6,1,1,1,0,0,0,1
