No promises or implications here regarding me ever releasing work, buuuut is there a still-living codex link anywhere on the world wide web? Darkfire's ancient post is unsurprisingly gone and the links in posix's LL tutorial are dead. I wouldn't begrudge a PM, but if it is being hosted publicly anywhere, this topic could hopefully make it easy to find for anyone else trying to hack a 22 year old game
EDIT: jfc I didn't even know we had that game utilities page. feel free to delete.
