To quote from his comment on xorloser's blog, linked above:
I just release my lv2 kernel decrypter You need metldr, lv2ldr, RL_FOR_PROGRAM.img and lv2_kernel.self. You have first to dump your metldr from FLASH memory. lv2ldr you will find also in your FLASH memory or in decrypted CORE_OS_PACKAGE.pkg from PUP files.
RL_FOR_PROGRAM.img is a revoke list for programs and can be also found in PUP files. lv2_kernel.self is on your FLASH memory or in decrypted CORE_OS_PACKAGE.pkg.
First i send all files to PS3 and store them in memory. After that i load metldr in isolation mode and pass it the addr e ss of lv2ldr. The code is very low level and many things are done by directly manipulating SPU registers
If you have any questions or problems then feel free to contact me or ask here. I will try to help you. I will try to document my findings on my homepage
I also uploaded a code which can communicate with USB Dongle AUthenticator by using Dispatcher Manager without using any GameOS functions It’s exactly what GameOS does, just low level
Have fun guys
lv2_kernel.self from 1.10 firmware decrypted
Guys, just to make sure that you know LV2 decrypter is also PS2 emu decrypter, just change LPAR auth id in code PS2 emu is like GameOS, it’s LV2 and is decrypted by lv2ldr
Just decrypted vsh.self from 1.10 firmware Just like old good days
I decrypted software_update_plugin.sprx but didn’t have time to reverse it yet
Physical/Virtual memory address of an isolation module that should be loaded by metldr is written into SPU register SPU_In_Mbox. The SPU register SPU_In_Mbox is 32bit, so 64bit memory address is written in 2 steps.
MFC relocation is turned off by clearing R-bit in SPU register MFC_SR1. By doing this, HV enables real address mode for MFC of SPU.
On GameOS, it also works with relocation on. You just have to initialize SLB of SPU and insert valid SLB entries.
Physical/Virtual memory address of metldr is written to SPU registers Sig_Notify1 and Sig_Notify2
Isolation load request is enabled by writing SPU register SPU_PrivCntl
Isolation load request is made by writing value 0x3 into SPU register SPU_RunCntl
SPE_load_request_metldr - 0x002B00A4 (3.15)
lv2ldr is used to decrypt lv2_kernel.self
syscalls 0x10042 and 0x1004A use lv2ldr
syscall 0x10042 is used by HV Process 3 during LV2 LPAR construction
syscall 0x1004A uses different parameters as syscall 0x10042
SPE_load_request_lv2ldr_1 - 0x002AE82C (3.15)
SPE_load_request_lv2ldr_2 - 0x002AE8D8 (3.15)
64 bit memory address of lv2ldr is written into 32 bit SPU register SPU_In_Mbox
metldr is loaded
Decrypting SELFs with appldr and lv1_undocumented_function_99
lv1_undocumented_function_99 loads and prepares appldr for SELF decryption.
When appldr is ready to decrypt data, it sends a message via mailbox.
The address and the size of the encrypted data is passed to appldr via a shared memory.

since the original playstation was originally developed as an add-on for the super nintendo, this patent may very well become it's own console. as far as gaming goes, sony was software only until nintendo screwed them over by canceling the disc drive add-on in favor of remaining with carts.
I think for this it would be like a cartridge like system interface...except it will house CPU+COOLER in these cartridges. Maybe 2 slots, and if the CELL had stayed on it advanced track as initially proposed, would just be swapping them out ever 4 years for the faster, smaller, less heat version.
This would only work with digital only content, because prior to purchasing the newest game it could then prompt you that your hardware is inadequate (that's not what she said ) and suggest you buy the upgrade. (maybe trade-in?)
I think, for the developers who put months or years of their lives into these games, they'd want to do those updates and make their work really shine. It's the publishers, and sony's own restrictions, that would make things difficult. Publishers don't want to spend any more money once a game is released, and sony would of course require the patches to be run through the full QA again, which means it's not just a fire-and-forget patch - the publisher has to keep the developers on payroll long enough to make sure it passes QA.
Ouch, so much for that. Oh well, one can dream... and nice Office Space reference.
In the next generation of consoles they should design them with upgrades in mind. It would have been nice to upgrade the PS3 to play games at 60fps instead of 20, and dare I say it... in real 1080p (outrageous, I know, since most games are not really even 720p). This is unlikely, especially since older games may have to be patched and we all know how lazy-as-hell developers are... especially those at Sega, Namco, Tecmo, Capcom, Squarenix, EA, THQ... okay, all of them.
