How to Load METLDR in SPU Isolation Mode on PlayStation 3


Sponsored Links
245w ago - 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 [Register or Login to view links].

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."

metloader=meatloader ie in the middle loader, metaloader loads all the other loaders lv2ldr (gameos), isoldr (isolation mode spu NOT iso9660 pirated games etc.), appldr etc basically we can also decrypt things with metldr too.

Indeed, am in no rush here. PS2 emulation is the holy grail for me.

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??

Basically the Devs would just be able to dump lv2 to examine, and I'm sure if CJPC did it he would "leak" it (assuming nobody beats him to it) for others without the required hardware to check out as well.

For end-users and non-Devs I'd say just to remain patient... the more people working on this the better of course.

well we could accomplish a multitude of things by running the METLDR such as mapping more of the cells architecture and i personally hope we can someday unlock RSX support for Linux so that i can run games in Linux... but right now its all still just a pipe dream
