Nice find. I noticed the people creating that site are well known in the Amiga community. Especially "Chain".

As for stripping game assets. There are quite a few tools for doing this in the Amiga scene. The demo scene groups were especially good at creating tools for this, as they often asset stripped content from games to use in the demos. These tools can normally extract the sprites, mod music files and other graphics from the game code. It would be cool to create a thread to explore these tools and see how well they work.
