Title says it, is it possible to change textures and music without closing the game? Like on title screen or something?
What do you mean by "Closing the game"?
What does closing the game mean?
I think he means without exiting the game and restarting after adding new content to the card. It is pretty tedious.
Try this (http://forums.kc-mm.com/index.php?topic=51912.0).
just take out the sd card, edit it, put it in, and back out of the css.
