SONY patents method to emulate PS2 on PS3

A patentdiscovered by Siliconera, however, suggests that Sony might be re-thinking this stance. Filed in December 2008, it's basically a patent for a method that would allow the PS3'sCell chipto translate code from the PS2'sEmotion Engine. Not half-assed software emulation (which in previous PS3 models couldn't run some games), full, total replication of the functionality of the Emotion Engine.

Which means, theoretically at least, you could play any PS2 game on any PS3, regardless of the model or year of release.

the amount of Win is overwhelming, My Friends will get to play PS2 games AGAIN :DTheOldOlder

Can't you play ps2 games on PC oh wait .... tos dismiss me from saying any thing about emulation:|

Ps3 cannot outmatch the 360's GPU resistance is futile

This is one of the steps that Sony needs to take if they wanna boost their place in this gen... the other one is also rumored so Sony is probably going to tunr tables here.

There are a lot of steps between a patent and an actual product, but hopefully this pans out.

this is epic win if they can finally implement this.

would be sweet if this turned out to be that false-hyped Update 3.0

would be an amazing Christmas present from Sony to PS3 users.

Didn't Sony also patent something called PS Cloud or something like that? How did that go?

But my PS2 allows me to play import games... will the PS3 will still be region locked?

Though, it is good that they are actually caring about BC... because it'll be a cold day in Hell when MS finally decides to let me play Curse of Darkness on my 360 in HD.

some games will play good without a super beast pc like fire pro wrestling R but big games like God of War won't work.

Triple post?

[QUOTE="JigglyWiggly_"] Not really, there a lot of problems with pcsx2, requiring a beast of a pc is one of them. Also there is nothing illegal about the emualtor, all it does is emulate the hardware, the bios however is illegal.

yea the site was buggy for a while

The PS3's BC ability seems to be a bit confusing to many ppl.

The original 60gb model had the EE (Emotion Engine) and the GS (Graphics Synthesizer) in the hardware.
The later 80gig model emulated the EE with the CELL but still had the GS chip on board.

Today's models have neither and that's why at this point, the newer ps3's cant play ps2 games.

In other words this patent was already used in the 80giggers.

They need to find a way to emulate the GS too. To me BC isn't really that important since i still have a fat working ps2, but up-scaled ps2 games would be great.

LOL the pix reminds me of this:

Eh. I already could play ps2 games on my...ps2.

quick questions to those who have b/c already. is it region-free like ps3?funsohng

Probably not; the PS3 wasn't region free for PS2 at launch and isn't for PS1 titles either.

I'm beginning to suspect there are legal agreements involved that we are unaware of. Developers may have pushed console manufacturers for region locking, for example.

Not really, there a lot of problems with xxxxx, requiring a beast of a pc is one of them.JigglyWiggly_

Without getting into detail: it's actually been very rapidly improving. Using the latest subversions, a number of games are fully playable, at full speed with a powerful processor (Core 2 Duo ~@3GHz or better.) And they look better to boot with texture filtering and a higher internal rendering resolution.

The major issue at this point is that games tend to be really picky about which specific plugins you use and how they're configured.

Also, using a BIOS dump is not illegal if you do it yourself (though I highly doubt anyone actually goes through the trouble of that.)

Edit: Removed emulator name. Might be a good idea to edit it out in your post, Jiggly.

i hope this happens

BC support + price cut = transformation into a cow

a 2ghz PC can easily emulate dreamcast atfull speed, and since PS2 is only a tiny bit more powerful then you dont really need a very powerful pc at all

This is how it for gamecube/wii and ps2:

PS2: Complicated to emulate

Gamecube, easier to emulate, bad documentation.

I have an '07 80GB with PS2 emulation. I've played a few PS2 games on it and it works fine. I have to wonder if this new technology would be more efficient or beneficial.

Also, you think they would be selling it on the PSN or release as a firmware update?

Yeah, I know emulators aren't illegal. It's just that I've been moderated in the past just for mentioning an emulator by name. Also, BIOS dumps & game images aren't illegal, but making unlawful copies/dumps and transferring them over the internet is.

A number of PS2 games emulate at 100% speed if you have the hardware. I'm currently (re)playing through Star Ocean 3 at an internal resolution of 2880x1620 (downscales to 1080p when I'm in full screen. Doing so gives a very high quality anti-aliasing effect akin to supersampling.) ..and my framerate never strays from 60. Still, some of my other games definitely cause my i7 920 to sweat with the emulator in its current state.

And yeah, Gamecube/Wii emulation has definitely been progressing even faster as of late.

I wish Sony in the meantime would just remove the region lock from PS3's capable of playing PS2 games. I have a 60GB one but from Asia so I can't play PS2 games. (by this, I mean most Asian releases don't have English or are extremely rare)

Fortunately a lot of great games got ported to the PC...and I have a pretty beefy PC to boot.

Well they're taking their sweet time about doing anything with it. It's been 7 months already.

awesome if true, cause my PS2 has taken to not reading Dual layered disks recently -_-

Open it up and clean the lens with a q-tip and rubbing alcohol. Especially if it is a fat model. I had to do it many many times back in my PS2 days. It's real easy and has like 29890234898423 tutorials online.

Pcsx2 sucks, really now you can't play fighting games like dbz ('cause they'll only run at abou 40-50 fps tops) also no GOW :(

If this is true and an update featuring ps2 compatibility comes out this year i'll be very happy indeed :D

:3 Would be nice if it added 4xAA like 360's bc. I'll take vanilla PS2 games though...:evil: just add BC Sony!killab2oo5

Not that i tried any original xbox games in my 360(i never owned a orginal xbox) but i do know that the 360 only has bc for some games(don't know which)
