wrong place much?
to make a new title screen just take an image that pertains to your game, re size it or crop it to 640x480. Add in a title using paint or photoshop then your done.
Changing fonts can only, to my understanding, be changed blanketly..if that makes sense
go to the main script, and i believe its line nine, change the name of the font to whatever you want.
animated title screens can be done with one of mogs scripts
