Well, it all depends on how your original map works. jamonathin's method isn't too bad - though for a more detailed map you'd likely use a series of Pic.New()'s and Pic.Scale()'s. Another possibility (if your map has some grid-like basis to it) would be to assign a specific colour/shape to each type of object on your screen and display them on your map. For example, traversable terrain could be green, non-traversable could be brown, your player could be an arrow pointing in the direction of movement, etc etc. This would be pretty easy to pull off if you already had your entire map stored as grid-pieces in an array.
