Sony Patents PS2 Emulation for Cell Processors

Siliconera - As the article states, the only reason for Sony to do something like this is for software emulated PS2 backwards compatibility in the PS3.

It just leaves the questions of if they will follow through, when will it finally happen, and how will it finally happen (disk + downloads or just one or the other?).
 
It would be great if all PS3s could finally play PS2 games. Hopefully this isn't just to sell digital releases of PS2 games.
 
I'd like to see a massive library of PS1, PS2, and PS3 games in the Playstation Store. Coupled that with their other entertainment products in the same store and Blu-ray, it'd be a hell of an entertainment system.

No wonder they were so liberal about HDD upgrading.
 
This will enable me to play the entire God of War series instead of just the third. I like this.

Even that would be better than the 0% for the current generation of PS3 hardware.
 
I'd actually put it more likely to be "per title" emulation. There's got to be some sort of return on writing this sort of software, and it's not going to come from used PS2 game sales...

I believe I read it on Kotaku, but they said it would allow for near 100% compatibility.

I read that article on Kotaku, and they claimed that this wasn't "software emulation". They have no idea what they're talking about.
 
So how is this different than what they did for the first version of 80GB PS3s? Wasn't that implementation already emulating the PS2 CPU (Emotion Engine)?

Yes, it is actually the GPU emulation that is the missing component. So on the surface this patent doesn't really mean much.

There was actual PS2 hardware in the G1 PS3s, iirc.

Yeah, it was but this is a patent that was filed in 2008. Well after the 80GB PS3s were already emulating the Emotion Engine. This PC World article picks up on that is wondering if this is something new or just a 'routine followup on old technology'. He goes on to state not to get your hopes up. 🙁

Correct me if I'm wrong, but I think:

PS3v1 had an EE chip for PS2 BC
PS3v2 had software emulation for PS2 BC
PS3v3 have no PS2 BC

Almost...

PS3v1 had an EE and GPU (GS) for PS2 BC
PS3v2 had the GPU and software emulated EE for PS2 BC
PS3v3 have no EE or GPU and thus no PS2 BC

So then they took it out of the G2 PS3s only to turn around and sell it to customers? It seems like they're optimizing it then. Furthermore, they probably also wanted customers to miss the product enough even though it's something that should've come with it initially. Kind of like Apple putting cut-n-paste into iPhones, lol.

Well, there goes my theory.

You're wrong. The PS3v2 had a hybrid BC scheme, where the CPU was emulated in software and the graphics chip was not (it was on-board physically). If it was pure software, it would make zero sense to drop it.

Patent applications take time to write and file... it's not entirely implausible that this is deriving from the previous PS3 hybrid emulation scheme.
 
It seems that the important bit is the Graphics Chip not the Emotion Engine. So they need to file a patent on that part too. Also I was reading on GAF that on every PS3 firmware there are special files for PS2 emulation. These files are there even on the new non BC PS3's. Another interesting thing I was reading was that engadget Japan found out that Taiwanese firms have been awarded contracts to create the PS3 slim and ship it by early July. These Taiwanese firms are the same firms that made the original PS3s. So I guess the only thing missing (now that we have slim coming and BC coming) is a price drop.

This

My PS2 died and I never got to play any of them. I want to pick up a PS3 later this year with the rumored price drop and want to play the whole series.
 
Ok so I have to ask. Why do they need a patend on something they should have the rights to anyway? Also I still after all of this time do not understand why they are having sooo much of a hassle to get BC working on the PS3. You can easily get an emulator for the pc that will do the PS1 and the PS2 that works. I understand that the playstation has a different OS but its simply a software code type of issue not a hardware one.

You have to remember that patents in some organizations are just another thing that engineers use to make themselves look good and pad their resume. I doubt it has much to do with "need".

They're not having a hassle. They're _not trying_. PS1 emulation works on all PS3s - it's just software.
 
Right but im refering to ps2 BC that they did away with. Erwos I know we dont see eye to eye on alot of things but I simply dont get why they had to have this chip to do ps2 BC and then they took it out and did software emulation which was what 75% compadable only to take that out as well? I remember all the stuff sony claimed saying that they were loosing too much money on the consoles etc but I still argue that there is no way that the numbers released to us were true. No business would run a product that they didnt make a profit on.
 
/shrug

Doesn't interest me since my launch PS3 can do everything. Nice for people that bought a newer PS3 or none at all yet though.
