But it doesn't seem to be in the port either. At least it doesnt show up for me when i play it.
Actually, is there a list somewhere of what models are in the mediaVPs and which arent? I looked at the HTL Status thread, but i think some of the models in there are in the mediaVPs even though it doesnt say so there.
you have to put it in the ports' data folder. the data folder has the same structure as the vp files do; however, data in the data folder overrides what is in the vps if it has the same name. Place the files inside the data folder in the correct subfolders and you'll see the new apollo. It's like this for every mod - each one of them will have a data folder, even the mediavps.. this way you can override what's in the vps by putting stuff in the data folder of the mediavps directory. You should never put anything in the Freespace2 data folder; it might work but it can break retail and it's just a messy way of doing it. You can use the Freespace2 data folder for an idea of the general data folder structure for each of the mod "data" folders tho.
If you get really advanced, you can create your own vps of those datafolders and give them names starting with a_ so that they override the mediavps or mod vp files, this way you can modify your stuff without affecting the data, and throw the vp files you created away when a new version comes out that incorporates some of your additions / changes (this happens to me often)
