Dean who is known for his work on the popular PS3 backup manager, multiMAN has confirmed that the Direct Boot function that is already incorporated in his manager doesn’t have to use the syscalls but instead directly executes the EBOOT.BIN so that it will work without path redirection.
What does it means to the end users? For starters, when Geohot releases his tools that are needed to sign the homebrew, the multiMAN can also be signed and then the Direct Boot function can be used which means you can play backup games on Geohot’s CFW. However, not all games support Direct Boot function. Like Dean says, it’s 3 out of 10.
I posted about that couple of days ago. multiMAN’s direct boot doesn’t use syscalls, but executes the EBOOT.BIN directly, so it will work without path redirection. Of course it will work just for couple of games (I have 10 and 3 of them work).
You need a way to make the PS3 system to execute an EBOOT.BIN, not the game itself.
