- Another brief update based on the yesterday's findings: the PS3 Flash is quite accessible as the majority of it is mounted inside the PS3 as a filesystem (think PSP), and is able to be read/written.
A picture is below for a peek at a partial filelist. As you can see there are quite a few sprx's. These are encrypted of course, however they function quite the same as their PSP counterparts. For the majority of the PS3 OS's functions, there is a sprx that is tasked to do the job.
For the big chunk of interesting news: Every single scene release ever released for PS3 will not work without being patched.
Why? It is because backup PS3 images lack some data that we will call a key. On an original, when the disc is inserted, the PS3 reads the key, and it is used to decrypt any encrypted files on disc (the DISC layer of encryption). On a backup, the PS3 can not read this key so it will not be able to decrypt the file. Of course if a hardware mod surfaces this could change.
Making a patch is simple though, use an original disc, copy the file back off through the PS3 OS, and rebuild (we are currently using a modified BRDGen for our tinkering). This is being done via debug machine as we can both make and run our own code on it, but should retail consoles ever be able to run backups it may...
