Thanks for the info. :). If you look at the description you will see that the graphic is by an artist called Ansimuz (Pixel Art) and this is freely available. The version of me was adapted to 32 colours, so that the graphic is usable for the Amiga. It's all in the credits.
Well they ripped someone off... :(
