I've been a little reluctant to give it up... I started trying to convert it just before I was invited to join the mod team. I haven't touched them since 2006 according to the last modified date of the files.
I started converting them and then learned about send-message-list sexp and decided to start from scratch again, using that. Then I found out about the pit-falls of using them so I restarted using a few new skills I picked up, so I've got a few different sets of missions. The only reason I'd include them if I pass the set along, is because I may have gotten further on the translations (that is managing to interpret what the poor Russian-to-English already in the missions actually meant to say) of some of the earlier incarnations of my missions than on the later ones.
The original missions used a specially modified Nova, including new textures, special weapons, and a stronger hull. In the missions I just used texture replacement, some more powerful weapons from the existing pack, and the special hitpoints option in FRED. The missions also used a Sathanas as a stand-in for a Shadow Vessel, but I switched it for the proper model. The newer Nova model may require some new textures for the replacement, but SPOILER since the ship is basically a shadow Nova, someone may want to take a crack at actually modifying the model with more than a texture replacement.
