Dolphin on PS3

OC your Cell to 6Ghz (dont know how ?)

1. Install some PPC Linux on the PS3.
2. Install Qemu on PS3 Linux.
3. Run WINE in Qemu.
4. Run Dolphin in WINE.

Probably wouldn't run or run well, if it could run it would be molasses slow. VM's and emulated hardware don't have acceleration, and if they do have acceleration they don't have adequate features to run an emulator such as Dolphin efficiently.

VMware has acceleration and yet can barely boot any games in Dolphin, I got Windwaker to boot but was slow as hell. PS3 doesn't use the x86 and x86-64 architecture, so they would only be able to run applications compiled for PPC, same reason VMware can only run guest operating systems compiled for x86/x86-64. Without hardware acceleration or access to the GPU, it is moot anyway.

and then you would have 2MB-4MB of free ram to run the emulator Wink

what the PS3 needs to be usable at all is:

-at least 1GB (better 2GB) System-Ram (+512MB ram for the GPU)
-a GPU like the xbox360's with unified shader support
-complete hardware access in Linux.

only then it would make sense to write the emu from scratch for ppc.
only then you could expect a playable speed.
only then i would buy it ^^

the PS3 is NOT a PC like sony is trying to sell it to the stupid.

a personal computer has no restrictions in hardware access.

have you seen how long it takes to boot winXP with Qemu?

it is worse than booting XP on a 486/DX2! (you click start and wait 30 seconds for the menu to pop up ^^)

Yes jk ^^

Btw , as seen here : http://geohotps3.blogspot.com/ , finally , someone made it ,and has now full access to hardware of the PS3!(friday 22 january 2010)

Frickin Awesome ,

Cheers!

Hello hypervisor, I'm geohot
I have read/write access to the entire system memory, and HV level access to the processor. In other words, I have hacked the PS3. The rest is just software. And reversing. I have a lot of reversing ahead of me, as I now have dumps of LV0 and LV1. I've also dumped the NAND without removing it or a modchip.

3 years, 2 months, 11 days...thats a pretty secure system

Took 5 weeks, 3 in Boston, 2 here, very simple hardware cleverly applied, and some not so simple software.

Shout out to George Kharrat from iPhoneMod Brasil for giving me this PS3 a year and a half ago to hack. Sorry it took me so long Smile

As far as the exploit goes, I'm not revealing it yet. The theory isn't really patchable, but they can make implementations much harder. Also, for obvious reasons I can't post dumps. I'm hoping to find the decryption keys and post them, but they may be embedded in hardware. Hopefully keys are setup like the iPhone's KBAG.

A lot more to come...follow @geohot on twitter

^Good news indeed

**Xtreme2damax** · 01-25-2010, 04:38 AM **#16**

He didn't mention the GPU, just the processor and read/write access to the memory and the ability to run unsigned code. Access to the RSX GPU is what everyone is after and without that running emulators or anything that requires graphics processing power is moot, no the SPU is not enough as mentioned.

I see nowhere where he mentioned he gained access to the RSX GPU for unsigned code, if I happened to miss that tidbit I apologize.

You re right Xtreme , but its a nice step for Emu ,sort of ... ^^ Right ?

**Xtreme2damax** · 01-25-2010, 09:13 AM **#18**

Yeah, pretty much. Better than the former situation where the PS3 remained a brick, steel and mortar fortress for little over a few years. I don't think the Dolphin team would be up for porting the emulator though, a third party developer not directly associated with Dolphin would probably pursue the tiresome task of porting the emulator to another platform.

Ok now going into full hypothetical mode.

Seeing how the PS3 hardware is mostly the same on all models, is there the possibility to make a kind of platformless emulator that boots the console like an actual OS?
That would save the RAM used by a Linux OS and allow games to directly acces it instead of emulating it, and emulating the missing devices wouldn't be such a resource hog after all.

... this of course, if all that there is to be known about the PS3 was already reverse engineered.

I'm glad you said you're in full hypothetical mode, because you won't be as disappointed when I say no. Technically, it's possible. However, the massive amount of work required to target that tiny possible userbase isn't worth it for the developers, who are working for no pay and are doing this in their free time. Besides, console specifications are lacking, so it would run games very slowly. Not only would they have to rewrite the emulator core to support the Cell processor, but they would have to create their own software interfaces with the PS3 hardware, effectively creating their own operating system when a perfectly usable one, Linux, is already available.

TL;DR: Not going to happen. Sorry Sad
