Any chance you could post a > little HOWTO to the list on setting this up? :-) It's a good solution for Linux, though I don't think JACK or the other stuff runs on Win32 though; it's *possible* you could build a similar kind of toolchain on Win32 though with whatever SDL is using for sound delivery. I'd be glad to write up a howto. It was fairly easy to do once I figured out the little gotchas.

The way I'd gotten it working before wasn't to write on the cdgSurfArray, just on the finished buffer right before it got sent to the screen. I think :) If that's still true, then yeah, I just need to update the UpdatedTiles chunk to tell it I've written changes there. Of course, the way I was doing it, I was just drawing the text on every frame anyway. I think I saved the rendered text and only changed *it* when necessary, then blitted it onto the finished output buffer right before it got displayed. Bleh. I need to dig some more to remember how I did it :) -- Looking for something to read?
