PS3 Where does PS3 OPL look for a hard drive?

[Rib]

@Rib Could you attach hex view of start of that executable? If it is XLF (signed ELF, some have stripped header), it cannot be changed just like that. Yet still, possibile external validation as another factor.

Not sure which executable you meant so here are all three:
OSDSYS (where the strings for the games that use HDDs + the Base64 strings are)

XPARAMS2 is also interesting, for every HDD game it has the parameters 0x02, 0x0B. Can't find any documentation on the parameter meanings (they seem different to the ones here) but might be worth looking into.

All these ELFs seems be just normal one, not XLF. So at least one problem less. Validation if exist (and seems to) is for sure fully on emulator side.

XPARAM2 rather not have any connection to security but IOP emulation. Maybe @uyjulian or @El_isra could have better insight on it.

 

[MrEWhite]

Has anyone by chance looked into this further? As previously mentioned, I can help test if need be.

@MrEWhite Not yet, but it is on TODO list. ;}
