Opening scroll? The text crawl in SP? It's a tga image that you can edit easily enough.
It's hard coded to be displayed after the Star Wars logo roq (this is a video file) has been played.
The 32 bit tga image containing the scroll text is menu/video/tc_english.tga. It contains no information on the RGB channels (just pure white), but the alpha channel contains the text.
