Finally got around to have a closer look at the Style files for the Lemmings 2 GFX.
My documentation is a bit messy on first glance, but I hope everything is understandable (feel free to ask if something is not):
http://207.58.177.175/~geoo89/lemmings/l2gfx.txtInterestingly enough, this file inludes how the sprites (
http://207.58.177.175/~geoo89/lemmings/l2gfx.zip) are linked to tiles (tree, wall block, etc.) which is actually not needed for the level format, however comes in handy for writing an editor.
I don't know what the L2OB section is supposed to contain, and I don't know exactly about the L2SS section, though it seems to be related to the cannon gfx. I made an illustration/interpretation for some stuff I found in this section (the gfx stored as describes are the ones with pink border):

Linking again, the level format description:

http://207.58.177.175/~geoo89/lemmings/l2save.txtApparently no-one has started writing an editor, and I'm utterly lacking programming skill for writing one. No matter whether anyone is going to do or not, I'll try to start learning some stuff on programming with graphical output (WinAPI?, whatever), and while that might take ages, after these ages have passed by I might give it a shot if no-one else is aiming for it. But note that the program would likely be crappy and unprofessional, and as said, only released within ages, literally.
