[0.5.0] [Duke] Duke splash screen corruption

[sinisterseed]

Seems the issues with the intros are back with a vengeance, but only in Duke as far as I can tell - Blood and SW are fine.

This is how the Duke splash screen looks like in 0.5.0.

I really need to do something about the palette hackery in these games. Using a global variable for determining which palette to use is a constant source of irritations and problems because the backend is no longer synchronous.
Too bad that this would mean a major bit of refactoring and possibly scripting trouble with the EDiuke frontend...

Well, it doesn't look like it's fixable without a refactor tbh. It just keeps coming back, doomed to never be fully fixed, so I suppose it's time to bite the bullet. Hopefully it won't cripple something else in Duke.

The corruption actually extends to end level screens as well now.

Fixed. For some reason these colors got a brightmap set.
