where find the default skins?
all the skin are in the repertory PaintSchemes except the default...

even with the keygetis "mod" i can't find this dawn skin...
( it would be usefull for minor modification for exemple put your name... )

I would imagine the defaults are hard coded some place, set away so they can't be played with
