Hi, I'm an amateur/demi-pro coder.
In the effort of making a first person dungeon crawler, I've remembered that F40 own an exploration section, and use a set of pictures to hint rotation and steps.
I was able to decrypt pictures many years ago, and there was some clever idea I cannot remember (and apparently no one nowadays seem to come with...).
So, in a word: did someone own such pictures, or an archive I can download? I don't mind the entire game, just those pics (or the .dat that contain them).
