For some reason I've always wanted to see the "insides" of Superfrog levels, and recently I've accomplished that and wrote an editor for Superfrog's levels and most graphic data. With the excellent help of JOTD it can directly manipulate the data files from the CD32 version. Even the Project-F level can be viewed, which reveals something odd...
Anyway, if you want to have a look yourself or play around with it, here it is;
As mentioned above it will need a CD32 version of the game, extracted to a folder on your harddrive. But all of that is explained in the included FAQ.
I should also mention that it can export maps and the objects on it to a bitmap, which might be useful for extracting complete game maps.
