Just a correction: PICT Resource 131 (not 810) in the titles file is the big splash screen you see when you open the game, and 8200 is the intro screen you see when you make a new pilot.
You also need to make clut resources for each picture (1000 for the splash screen, and 1001 for the intro screen). I don't really know how to manipulate clut resources myself, but I do know that you need them (and I'm inclined to think that you need to include something having to do with the greens used by the game in number 1000). (In EV Classic, #1000 is in the Escape Velocity App, but # 1001 is in EV TItles. In Override, both clut resources are in Override Titles.)
Hope this helps.

If I write a letter to be put in a time capsule to be opened when time travel is possible, and if in my letter I ask for some item to be sent back in time to the point I sealed my time capsule, wouldn't that item appear just as I seal the capsule? Just a thought...
