Recently I've been decompiling PAK files with PAKExplorer to get a better look at some of the mission pack assets. Luckily the source code for the Hipnotic and Rogue map packs are open source, so I've been trying to compile a new progs.dat with all the monsters and weapons to map with. I'm getting close... but there's always some conflicts with the data. Let me know if you are interested in this project, if you have any tips, or if anyone wants to take a whack at it themselves, I can provide some files to help.
