I just spent HOURS on this, redoing it from a scan of my ColecoVision box, only to find out that there was a second release with the exact same box as the CV version!!! Aaaargh! Had to move all the smurf locations from the front, and redraw the top part of the image. Ggggrrrrr! Oh well - it is my favourite Coleco game - so it's nice to spend time with it one way or another.
