Actually these weren't composed by Danzig, they're all converted .mod files (again!). I only know the authors to a couple of them, but I can try to track down the others.
The "Realm" trainer uses acidbat2.mod by Keith Tinman, from some Batman game on the Amiga:

http://modarchive.org/data/downloads.ph ... 17#ars.modI'll try to look for the other three later, but I'm fairly certain that they're also converted .mods (it mentions it in the scroll texts, I think)
