Okay, now I made another file (freighter02dc.pof). Now how can i insert it, pass the grog! How can i make a mod, to be sure? How can i create VPs? Is there any tutorial?
For what you want to do you don't need a VP...not unless you want to distribute it..
Basicly put that .pof in your Freesapce2/Data/models folder and re-name it back to the original. Now it will override the one in the VP's..
If you edited it with PCS2 (and made the .tl change) it will now have an additional subsystem in-game and in-FRED.
EDIT; .tbl files are simple text files with changed extension. You can open them with any text editor (Notepad, Wordpad, etc...)
