It's real simple. Make a folder on the root of your usb drive called GAMES (it has to be all caps). You can put your game folders (usually something like BLUS***** or "BLES***** - (SoAndSoGame)" in there. When you plug that drive into your ps3 and start multiman they'll appear in your game list. You can either play them from there or copy to your internal drive.
Remember that the USB drive needs to be formatted as FAT32 and that you can't put files on there larger than 4 Gigs. If your game contains files over 4 Gigs you'll either have to split the files or ftp them to internal
Fiery the angels fell. Deep thunder rolled around their shoulders... burning with the fires of Orc.
