No "666" splitted files are done by Multiman and similar tools because the PS3 is shit and only really supports FAT32 and 4 GB large files (in general, you could hack in NTFS). Even on a real PS3 you must join them or the game will never work. So join them with the splitter tool as Digitaldude mentioned.
