I've converted the files into a fairly readable format. It's not as sophisticated as actual mission scripts, but the files are fairly short so all is well.

Compare the raw data https://pastebin.com/CVUwJcmy with the same data but redundant garbage removed https://pastebin.com/6xUaruD3 with the final converted file https://pastebin.com/GWv15Gud

I've recovered most unresolved filenames, reducing the unknown files from 11000 to 50. Refer to this thread: http://steamoss.com/groups/pd2mech/discussions/0/333656722983521183/
