"Grand Theft Auto IV," commonly abbreviated to "GTA IV," is an action-adventure game for the PlayStation 3 console. Rockstar North developed it and Rockstar Games published it in April 2008. If you've already followed protagonist Niko Bellic through the game's single-player story mode and are looking for something new, you can try installing mods. Mods, short for modifications, are user-made content for the game. Mods can include anything from gameplay tweaks to entirely new content.
Start your PS3 and enter the dashboard.
Start your PS3's FTP client. Record the PS3's IP address. You will need this in order to transfer mods from your computer to your PS3.
Launch your PC's FTP client. If you don't have one, you will need to download and install one.
Find and open the "Host" setting in your PC's FTP client. Type your PS3's IP address into the "Address" field. The exact name of this setting and field may vary depending on your FTP client. Click "Connect" to connect your PC to your PS3.
Locate the GTA IV folder on your PS3's hard drive. The file path may differ depending on your system, but it is commonly located at "hddo\GAMES\GTA4." Open the GTA IV folder. Locate the "USRDIR" folder within your "GTA4" folder.
Find your downloaded GTA IV mod files. These are "common.rpf" and "PS3.rpf." You may have downloaded them in an archive file, so be certain you have extracted them. Transferring the archive will not work.
Drag-and-drop or cut-and-paste the two files from our PC to your PS3 using your FTP client. Overwrite the old files if the client asks if you wish to do so. Close your PC's FPT client once the files have finished transferring and return to your PS3.
Exit your PS3's FTP manager. Return to the PS3 dashboard and load your backup manager. Find and open GTA IV. Return to your dashboard. Delete any GTA IV game data. This ensures game compatibility with your mod.
Launch GTA IV. Refuse to update. Updating will render your mod incompatible, and may also prevent you from successfully launching the game. The game will install your mod.
Create a backup of your original "common.rpf" and "PS3.rpf" files so that you can reverse the mod when you finish with it. You may need to "jail break" your PS3 before you can successfully install mods.
