2. Put game ID to game ID field
3. Browse for needed files (there is no check so be sure u selected all)
4. Slect the Game folder and disk drive (8 chars only, hdd0 it should be)
5. Select the FW version
6. Click on EXECUTE
7. Watch how all it is done for you
Note: Path to game in the PS3 it is always: "dev_[selected drive]/[folderGameName]/USRDIR"
