The titletext is:
titletext ["Any text you want","PLAIN DOWN",1]
If you use custom Rsc's defined in the description.ext and use titletext the same time the other one wont show up. I've found a solution to this by using titlecut instead of titletext. The syntax is the same for both. This way the Rsc and text will show up the same time. PLAIN DOWN can be replaced with PLAIN which makes the text apper in the middle of the screen. PLAIN DOWN makes it appear at the bottom. 1 is the time which the text takes to fade to it's "full visibility".
titlecut can also be used with fades.
titlecut ["text to be shown during fade","BLACK OUT",4]
BLACK OUT will make the screen go black and BLACK IN will make the screen fade back so that you can see. 4 is the time (in seconds) it takes until the screen is fully black/faded back.
Hope this helps!
