Hi there,
I somehow came across this board when I stumbled upon Lemmings custom levels on YouTube. In 1996 I had written a Level Editor for Lemmings 2 The Tribes for the Amiga. A friends of mine, my sister and I had created a good bunch of levels with it and the 2.0 release in 1997 included 33 custom levels. I also had patched the game to allow selecting different level sets and the ability to just paint levels with a painting program (and of course you would still need to add some standard objects).
Way back when Hermann Schinagl wrote a converter (DOS tool) for those levels which fixed the big endian / little endian conversion between the Amiga and PC versions. I never owned a PC until 2008.
Anyway. I found an archive on my harddrive with the Lemmings 2 game, the Level Editor and the custom levels. I never had published it in this form due to copyright reasons regarding the original game. The archive (2 MB) can be extracted to any harddisk image of an Amiga emulation with basic Workbench installation and should be running both the game and the editor nicely from the Workbench.
I would be happy to provide the archive here to you, if anyone's interested. It's been a while, but it would be a shame to see the stuff getting lost after such efforts.
Let me know what you think and where to send the file to.
Cheers
Chris
