Editing - JO UI
You will need a Program that can Edit ".TGA" File Extension Types. You will also need a PFF Utility to Exract the files needed. You will also need it to Re-Construct the files into the game.
Now you will open the PFF Utility, Open File, go to the Joint Ops Folder and Open "localres.pff" Select all the files within that file, extract to a folder (Ex: JO Files). Now, open your Graphics Editor, then Open JO_epil.tga and JO_epil2.tga, put what images you want for that file, save and copy that from the folder and put into the "localres.pff" file, now your down, open Joint Ops and it should be there. Although it wont be for all screens, you will need to edit further files, .txt files and other files. These, you will need to Research on your own. Look threw the files and you will find them, edit them and your on your way to an awesome looking JO User Interface! :)
