How to Load METLDR in SPU Isolation Mode on PlayStation 3
Just over a month ago the PS3 Hypervisor lv2 (GameOS) was dumped and GeoHot hinted that it was accomplished by commanding an SPU to load METLDR.
Today dondolo let us know that simone has detailed how to load METLDR in SPU isolation mode on the PlayStation 3 and included some source code.
While this is definitely a step forward, he still doesn't specify what the read/write u32 functions are... or which functions to add to the recent XorHack release.
Those interested can check it out below, and to quote:
"After some experiment I succeded to load METLDR in spu isolation.
You need geohot's exploit to do this, because you need to turn spu relocation off (MFC_SR1[R]=0) and not let know the HV you are using a SPU (so no calls to lv1_construct_logical_spe or similar). For some strange conf, it doesn't work in HV way."

This is absolutely awesome! Thanks for the amazing discovery and all your hard work simone! I just wish I had a fat PS3 to try this out .. sigh ... I'll wait!
Nice to see things are moving forward but it looks like a usable hack is still a while away for the average user. Anyone care to share any information/theories about what loading METLDR will accomplish?

nice one, lets see if this will face the direction in the right way.
For end-users and non-Devs I'd say just to remain patient... the more people working on this the better of course.
now I'm not saying a hack is impossible but guessing that the encryption is based on mathematical prime numbers, and there are "quite a few" of those and since they never leave the chips they are built into a proper hack may never be found, but i hope to good god I'm wrong!!! and a homebrew hack is in the pipeline....
in the end i guess the only question we really need to be thinking about (long term) is what business model will win, will the Microsoft "we make money on every console so feck the software makers and loose on software licensing" or will sony "sell the console at a near loss but make a killing on software sold for our box" win out, this is the battle we really need to keep an eye on.... but will anyone at M$ or S0NY read any of these posts??
It was a while from a real progress till some time, nice to see that we are going ahead! Yeah ps3 is going down! At this time i hope that Sony cannot mess up all this work with software patches or can they?
