Title screen palette

Man, who would have thought the palette would have been the bitch part of this.






This turned out to be one of those situations where I have no idea why they did what they did. 

Changing the palette worked fine until I noticed part of it just magically reverted itself a little way through the title screen.  Turns out to achieve the text fading and transparency effects they do with the text that rolls across the screen, they keep about a million fucking modified copies of four of the palette's colors, and swap them in and out over time.  Once I picked through all of this and started generating all of these in the ROM export, everything was good.


Triple compression on this thing.  Compressed tiles, referenced by a compressed block of data that lays them out, all processed by a compressed block of code, and then they throw this giant table of colors in here, presumably to.. make up for the space saved by compressing the whole thing, I guess.  Sigh.  Whatever, it works now.
