If your background uses the second half of palettes 0 and 1, then no matter how many Fade Fix patches you apply, the background will probably never fade. The status bar uses those colors.
So I'm having some trouble with the fade fix patch. I know I'm applying it correctly because I've done it before with success (I'm using Xkas GUI, so it's not really easy to mess up, anyway). Now I don't know why, but it's just not working. The ExGFX I'm using for the BG can be found here http://www.smwcentral.net/?p=showexgfx&id=717. Now what happens is that the windows and streetlights don't fade out. Any suggestions on how to fix this?
