Apparently a well-known developer by the name of naoneo is working on her very own PS3 ISO Loader — FERROX! She has released a video demonstrating its supposed authenticity… Nothing more has surfaced for the moment, but on a brighter note, it is reported to work on ALL firmware versions — up to 1.51; thanks to a security vulnerability in the PS3’s Hypervisor.
Again, this should be treated as pure speculation, at least until something concrete and usable is released to the public. Nevertheless — time well tell!
