This program allows to simulate the dev_flash from USB. Allowing a Custom Firmware. We may modify the files of our new dev_flash (USB) as we please, without running the risk of throwing away the PS3. It is a beta version, probably find bugs. I will continue working on it when time permits me. Remember that suffers no risk to the console. All that is changed the new dev_flash'll be doing really USB.
