In the early days of PS2 modding, loading games from a USB drive was a notorious exercise in frustration. Gamers were strictly chained to the ancient FAT32 file system. It was a digital nightmare because FAT32 could not handle any single file larger than 4 gigabytes. To play massive, cinematic masterpieces like God of War or Gran Turismo , players had to use clunky computer software to manually chop the massive game files into tiny, fragmented pieces just so the console could read them.
