If you mean using the fade_in() and fade_out() routines, they won't work in truecolor modes because there is no palette to do the fade with. I know this sounds silly, but a simple fade-to-black is quite a tricky thing to implement in a truecolor mode. It can be done by repeatedly drawing translucent black rectangles to gradually darken the image, or using the lighting code to blit a series of images onto the screen while changing the brightness, but I think this will be too slow to get a nice smooth fade. Your best bet is probably just to think of some other cool transitional effect, and avoid the fade altogether! -- Shawn Hargreaves - shawn AT talula DOT demon DOT co DOT uk - http://www.talula.demon.co.uk/ "Pigs use it for a tambourine" - Frank Zappa
