hm ... one more guy...
Well, I've just started writing Ultima 0.40 today, and I think I'll keep trying around with these formats the next weeks. However, my documents are very out-of-date now. You should ask mirex, he's got a working converter, perhaps his format description is more up-to-date ...
I'll publish a new version of my description, as soon as my suspicions are proved...
