This is a very rough translation of the installation steps for this mod. I pieced it together and hope this is correct. All of the credit goes to the developer of this mod.
In addition to a map change, many vehicules also have new handing, vehicle boosters, rockets and reinforcment. To find out more, you'll have to play.
1 Get "packgtaxbox" from this site:
http://elrayzeur.fre...packgtaxbox.zip 2-Extract "packgtaxbox" into a folder on the desktop
3-Install GTA: Vice City onto the HD of the Xbox
4-Through FTP, transfer the files "gta3.img" and "gta3.dir" (they are inside the "models" folder). It is very important to make sure that both of these 2 files are in the same folder on the PC.
5-Download and install the program, "imgtool_1.3" (sorry, site not given.. try Googling it). Now, after opening the imgtool program go to File->Open and open the "gta3.img" file that you recently transferred (step 4). Next goto Tools from the dropdown menu and select Sort->Name This leads to step 6...
6-In the "packgtaxbox" folder there exists 2 folders, DATES and MODELS. Open the MODELS folder and notice the GTA3.IMG folder. Inside of this you will see folders for each vehicle (bateau=boat, motos=motorcycles, voiture=cars, sexy=billboard change, radar=radar change). The only goal for this section is to replace these new objects in place of the old ones. To do this find the file from the list in IMGTOOL, select them all, and in the COMMANDS menu select delete.
7-Then, in the same COMMANDS menu select ADD, and replace all of them with the ones given in the packgtaxbox folder. Do this for the entire list.
8-Now, go into COMMANDS and select REBUILLD ARCHIVE and then YES. Now wait for this entire process to finish...
9-no FTP the new "gta3.img" and "gta3.dir" files back into your copy of Vice City on the HD. After this is done replace the"data" and "models" folders (along with the rest) with the ones you received from the packgtaxbox folder. Before you finish you must delete the GTA_VC.CAP.Final file from the Xbox in order for the game to work. Now you can enjoy Vice City all over again with the new Ferrari, Porshe, Toyota, Ducati, etc... I believe that the same process edge Be made with with GTA3, "new" goal in the place of vehicules voces irao to uses "old vehicules" (did not know how to translate this last sentence.. sorry.. never took french).
