PS3 Hypervisor and Bootloader Dumped from RAM and More!


Sponsored Links
237w ago - We are happy to report that the PS3 Hypervisor LV1 and Bootloader LV0 are dumped from the PlayStation 3's RAM after getting our SX28 Hardware a few days ago, utilizing code for glitching and mashing buttons for hours - the exploit eventually will get triggered!

We tried a few different ways to dump out the real memory - the biggest "problem" was the fact that you can't just simply use File I/O code in a kernel module. Furthermore, you can't call the lv1_peek function from user mode either.

Luckily, resident DEV kakarotoks was up to the challenge. After some trial and error (and too many PS3 crashes!) he made a kernel module which maps the "real" PS3 memory to a device in /proc. The /proc area lets the kernel and userland interact some.

Basically, the device /proc/ps3_hv_mem is created when the kernel module is inserted. Once it is inserted, you can use dd to read the device. By doing this, the device gets passed arguments, which is passed along to lv1_peek - which in turns reads out the real memory.

Be advised, don't go beyond the PS3's upper memory limit. At around 260MB, the PS3 tends to crash - it does not like trying to read beyond RAM limits! So, for usage:

First, run the exploit, and get it triggered and working - that's the hard part!

Next, download the attached file, inside are three files, a Makefile, the ps3_hv_mem.c and a pre-compiled version. Stick these in a folder, and run make. It will then compile a kernel module for you (ps3_hv_mem.ko, or use the pre-compiled one). Then simply type: sudo insmod ps3_hv_mem.ko

Enter your password and check /proc for a ps3_hv_mem entry, or your dmesg. If it is there - let the dumping begin!

You can dump out the PS3 Hypervisor and Bootloader (and the rest of the real memory) via dd. You can use the command:

dd if=/proc/ps3_hv_mem of=PS3_Memory_Dump.bin bs=1024 count=10K

That command will dump out 10485760 bytes, or about 10MB - which nicely includes the goodies like LV0 and LV1. Finally, you can also increase the count, which will increase the amount dumped (multiply by blocksize).

lol well abandonware is just a term that pretty much means its either too old to be made again or the company that made it went under so no its not hippy term, just a term that is loosely used.

Technically no - hence they don't retail those products anymore it becomes Abandonware (i mean Nintendo don't support it anymore).
Actually, this is just an excuse that some people use to pretend that they aren't breaking copyright laws. Abandonware is just some made up hippie bs word that only serves as a softer euphemism for copyright infringement.

You might own the cartridges for all of the games you play, you might not. I won't judge because I don't really care if you do or not. Just admit that it's, at least in the eyes of the law, no different from someone downloading a game that came out last week.

On the actual subject of the PS3, I'm far more interested in just seeing it get cracked than anything else. This is all good progress, and I'm sure some of the things I'd like to see will come eventually.

Congrats/thanks to all of the devs involved. Interesting stuff.

Thanks for your work. I'm looking foward full linux on ps3. I have question full linux means linux like on 3.2Ghz proc pc, because now it so slowy.. and no 3D support. I keep my fingers crossed for you. Good luck!

Sorry for my english.

There are Demos out on PSN. That's no excuse here, the demos they already offer are feature-rich and would indeed be good enough to "try before you buy".

imo, I hope they don't release a backup laucher. ISO, sure, but backup DVD launcher = no.
I beg to differ. Demos are useless as they are. The last one to truly show anything interesting to me was that for infamous. I personally don't buy games I haven't pirated. Can't speak for everyone though.

Technically no - hence they don't retail those products anymore it becomes Abandonware (i mean Nintendo don't support it anymore). Besides if you own the cartridge (yeah so damn old) you have purchased the game and therefore would be allowed to use a "backup" of the game and play through an emulator.
Most people actually own these cartridges then? This argument goes for ISO loaders as well. Why should you assume all those using the system for emulators own the disc whilst those using it for loading backups don't? Emulation is just piracy of old or same as piracy. Even just having the rom even if you have the real game is shaky.

Last time i checked playing SNES games via an emulator is also pirating.
