please note that this tool does not work on the neocities mirror.
this tool is no longer required, as PS3 Toolset is now back online. when i hosted this, it was down. i'm leaving it up just in case.
this tool is designed to be run from the ps3 browser. it requires the 4.90 HFW to be installed. more info can be found at the PS3Xploit Flash Writer thread.
if you know what you're doing, you can continue to the tool here.
