Soooooooo...
The first custom .lev file.

(The crate is from my attempting to set up a tile cache effect, but it doesn't appear to work in 1.00.)


(LINF: from what I can tell, all sections are padded out to a multiple of four bytes, whatever their contents. That means that LINF doesn't just have a lot of padding; instead, it has eight (layer-related?) longs, all of which seem always to be zero, prior to the padding.)
