Ifcaro has released the source code to his PS2 USB Advance ISO loader which currently only runs on the first Japanese PS3 console released. You can find the project over at Google Code. I suspect even if this can be made to work on other regions of PS3, you still need the early revision with PS2 hardware included.



YES, you must have a console with ALL the PS2 Hardware, which is the first release 20/60GB consoles; to even TRY to get this to work in the USA.
