There is a good example of using and setting up animated sprites in the Dark Invaders tutorial that comes with DarkGDK.
Alot of the sprites in that game are animated, I think it should give you a basic understanding of how to setup your own animated sprites. Then, once you know how they are working, I dont think it would be too hard to customize the techniques to do what you want or to work with different image types.
Also, the very first DarkGDK "Hello World" tutorial(the one matty halewood is referring to I think) uses a very basic animated sprite method to rotate a pic of an earth globe.
Both of those tutorials have well written PDF docs that you should be able to find somewhere in the folders for the tutorials. The PDF's walk you through, in a step by step, written for new DarkGDK users manner , how the tut's work and how the commands work and how to set them up etc.
Hope it helps
If it ain't broke.... DONT FIX IT !!!
