While browsing the Spanish dorums daxhordes, I noticed a very interesting topic.
Apparently, after officially stopping production of Ps2 system, Sony has started to hire Ps2 developers to work on Ps2 emulation debugging.
Here is the picture from daxhordes:

And if you don’t believe this, then you can see the source in the official page here.
Now, I’ll just use this as an excuse for one of my lectures, this time, about Ps2 emulation on the Ps3 and the history behind it.
The Ps2 was a very complex system, it was hard to code for and this has also resulted in being harder to emulate. This explains why the Vita can emulate the psp, and why Gamecube/Wii emulation was done faster than Ps2, achieving higher compatibility in less time.
To achieve Ps2 backwards compatibility, Sony didn’t even resort to emulation, they basically grabbed a Ps2 and incorporated it into the Ps3. Both the Emotion Engine (the Ps2′s CPU) and the Graphics Synthesiser (the Ps2′s GPU) were soldered into early Ps3′s mother board. This allowed perfect Ps2 compatibility for the Ps3. The Ps3 models that used this hardware were the Japanese and American 20Gb and 60Gb models.
As time passed on, Sony decided to cut costs, they did so by removing the EE and using the Cell BE (Ps3′s CPU) to emulate it. At first, this caused a decrease in compatibility, due to the crappy EE emulator, but it then became better and games such as MGS3, which previously lagged, now run smoothly. The models that saw this change were the 60Gb Pal and 80Gb American models.

Wanting to reduce more costs, Sony decided to remove the GS and tried to emulate it using the RSX (the Ps3′s GPU). This was a complete catastrophe, not only didn’t it work well, but it dropped compatibility down to 30%. Now, this (crappy) emulator exists in every Ps3 out there, so in a sense, all ps3s are backwards compatible, but they have that disabled for discs. This is the reason we see Ps2 games on PSN, because these Ps2 games were lucky enough to be on that 30%.
Here is a sum up of Ps3 consoles and their BC status:
Ps2 Hardware: EE GS IOP
20/60Gb US/JP: Hardware Hardware Software
80Gb US, 60Gb PAL: Software Hardware Software
Others: Software Software Software
So, what is needed to have full backwards compatibility?
First, the RSX can only partially emulate the GS, to fully emulate it, the RSX might need help from the Cell BE. The problem is, the Cell BE is already fully used:
Core: task
SPU0: IOP (the ps1 CPU found in the ps2)
SPU1: EEDMA
SPU2: Isolation
SPU3: IPU
SPU4: GSEGFIF
SPU5: PS2-SPU2
SPU6: VU1
SPU7: not used (factory disabled)
PPU0: PS2-Devices
PPU1: Emotion Engine
As you can see, the way this emulator works right now leaves the Cell with no room for anything else (except the SPU5, which is about 50% loaded, and the SPU7, which is not used), so to have the Cell BE assist the RSX in emulating the GS, there has to be a complete re-map of what the SPUs and PPUs do to get more room. Maybe enabling SPU7, but if Sony disabled it for a reason, I’m willing to bet that reason was overheating.
With all this said, it’s up to Sony to decide what they want to do to the Ps2 emulator, will they leave it like that? will they improve it? will they re-write it? only time will tell.

Sony has stopped PS2 backwards compatibility for cost reduction and because the PS3 catalog wasn’t empty as the beginning! What Sony wants now is having a perfect compatibility PS2′s emulator 100% software only in order to sell more games on PSN : Sony doesn’t re-introduce backward compatibility for PS2 games discs !
-
It’s late in the game but I wouldn’t mind seeing PS2 emulation make a comeback to the PS3…
-
I hope this means they will perfect the PS2 emu for the PS3, but maybe this is actually about an emu for the Vita or even the PS4? The preferred skills lists makes it sound like PS3 but who knows?
-
Seriously…. I don’t really care if they are gonna resume ps2 emulation project on ps3 or not. I just want to play some of my favorite ps2 title on Vita, all in all, I wish they start making ps2 emulation on Vita instead.
-
I have the first generation of PS3 ( the one with Emotion Engine inside ) means full PS2 Backward Compatibility , is there is a way to play PS2 Backups or ISO’s with the current CFWs out there ? I am crrently on 3.55 Kmeaw.
Any tips will be appreciated. Thanks
-
Of course, you will just have to buy the Cobra USB Dongle for the PS3. It allows PSP and PS2 back up loading on any PS3. (Non-backwards compatible models though can barely play any PS2 games and none of the ones that load play almost at all, BC models play the games just as good as they would play the original disc games).
-
-
mayb they made there mind to make a ps2 working with psvita yeah they looking for a ps3 experience devs so that they can easily understand the psvita system
-
i doubt it’s for ps3..
ps4 and vita are more likely
-
Sony!!!! Make that emulator for vita!!!! pleace!!!! that will be really nice!!!!
-
Some PS2 titles only use standard libraries for the VU1 and the IOP and Sony could use HLE for those. Then they’d only have to really emulate the VU0 and the 5900 which the PS3 and Vita ought to handle without a problem. That would probably account for around a third of the PS2 library.
-
LOL all of you are missing the point here – sony is making it for the PS4 , vita won’t get this or ps3, the ps4 will come out with a few surprises
.
source – Sony snitch employee.-
The next PS is apparently going to be called the PlayStation Orbis, and not the PlayStation 4 (as 4 is Shi in Japanese which apparently means death) – also, the Orbis will not be backwards compatible with PS/PS2/PS3 games (at least not discs – but by either downloading from PSN or streaming to your PS Orbis – complete with ads). The Xbox3 will have BC, though uncertain as yet to whether that is Xbox and/or Xbox360 – or whether that will be region-free or not)
-
-
As much as I would love to see it for PS3… I think Some people are right as far as it being developed or “fixed” for use on the PS4, But I also think that this could be also available for the Vita, and POSSIBLY (just a speculation) the Sony Xperia line of phones…

Job was posted 6 months ago. What makes this so NEW?
Abraham Lincoln was shot in the parking lot with a 357 upside his head many years ago. It’s not New NEWS. It’s old and thus should be labeled as such.
-
Not to mention it ENDS in 3 days.

great article! answered some questions I had about emulators for a while. thanks
-
I enjoy browsing the Spanish dorums too.
Its naughty
good read though

I know one thing and that is this will never lead to full software ps2 for old discs. $ony will do this only in the name of more money. It could be they want to get more PS2 classics on PSN or they want to get PS2 classics on Vita. I would be shocked if they do anything for PS2 discs on PS4. They are not going to do anything to help you play old games you already own on PS3 or PS4. They made this clear when they ditched the UMD loader for Vita. As a result I have repurchased numerous PSP titles on PSN so they seemed to have made a good financial move even if it blows. Thankfully now we have eCFW for Vita so I can stop paying $20-$30 per game for PSP titles I already purchased once. My whole gripe with PSN and Nintendo is the price structure for classic games. If last gen (PSP and PS2) games were all 10 and under and older games were 5 and under then I would buy a lot more stuff…..my god Nintendo is charging 5-10 for old GB and GBA games. It is a crock as that stuff should be like 1-2. These dumbos could learn a lot from apple and the app store model. Most of these classic games have already made millions and millions of dollars and cost next to nothing to develop unlike todays full releases. Why not show some love and share the joy and let us old school types enjoy our nostalgia for a reasonable price? End of rant…lol

It’s called capitalism?
Basically, they will try to squeeze every last dollar out of their market, and the temporary nature of their management and compensation ensures that they will consistently prioritize short term profits over long term brand loyalty, dedication, or customer satisfaction. They don’t care if you owned the game before, because if you really liked it then you’ll buy it again – you’re a mark, in the scammer sense. It might make more sense to sell with slightly less profit to make two to five times as many sales, but it’s not as easy a decision for the people in charge.
Despite my snarky introductory sentence, I completely despise capitalism as a model for society or the economy – almost as much as the crony capitalism of the US and most of the world – and it’s clear that it causes companies to essentially plunge to their “deaths,” but there is little to do to prevent it other than large scale social and (some) educational reform. People who are distant from the negative effects of their actions will always choose the option which benefits them the most personally.
-
Well I have to disagree with your spin on capitalism being a US citizen I don’t think any form of social design has allowed so much upward mobility. I came from very humble beginnings and did not even finish college but managed to use my technical prowess and love of tech to build a succesful career as a consultant and then used my entreprenueral talents to start a business that I used to both employ numerous people and made a decent purse for myself when I sold my shares in 2010. I essentially pseudo-retired by time I was 40, although I am cooking a new concept now and getting ready to start a iOS/droid development company to make diabetes apps. Corperations don’t hold a gun to anyone’s head to make you purchase anything. They rise and fall strictly on the merits of there products and services and their profits are based on the quality of their management team and their decisions. All social systems have shortcomings but I would far rather be placed in a captalistic system then stuck under the socialism of Russia/China or the tyranny of the 3rd world. The only people who suffer under capitalism are the talentless or the un creative, but even then in America we have created such wealth that many people just suck off the system and do little to be productive but still have PS3s, cars, and iPhones someven the poor here live like kings compared to those in poor dictatorial nations! Long live captilism and America!

@Acid_Snake, wtf are you talking about within these comments? Kill3r is totally right, you honestly think that Sony after having the PS3 out for the last 6 years and doing nothing for 5 of those years with regards to PS2 emulation updates is suddenly going to release a new firmware etc. to allow everyone on every PS3 to play PS2 discs? Dude lay off the crack and with regards to someone asking about the current state of playing PS2 backups/ISOs, the best way by far is with a Cobra dongle (who have just announced a new CFW for 4.xx PS3s) via mmCM as you can play PS2 backups/ISOs, hell even stream them from your PC. Did you refer to this? No, just gave some answer about Swap Magic…this isn’t 2007.
Bottom line there is no way in hell this is pointing towards playing PS2 discs on PS3, it’s improving PSN PS2 Classics compability and/or for PS Vita/PS4/Xperia.
Oh and there’s a part of your article which is wrong as it wasn’t all 80gb PS3s that were BC, there were only the first batch of them with 4 USB ports (just like the 20/60gb PS3s) as all of the ones that came after the Motorstorm/MGS4 bundles do not play PS2 games.
-
True that dog as I have both a SW BC 80gb phat and a non BC 80gb phat and BTW they were both sold in MGS bundles. I will say this the BC model runs hot on the right side of the case although it hasn’t croaked, the non BC fat runs cool as a cucumber with no hot spots anywhere. The early full BC fats were built like tanks and must have had extra cooling becaus they run cool but push out a lot of heat so need room to breathe. The early pats had crappy BDR drives though. For my money those late model nonBC phats seem like some of the best all around models.

Last comment…..which is I never understand why people care so much about BC. I mean if U care so much keep your old system…..at this point you can by a PS2 for $30, hack it with a memory card software exploit and either run games from HD or DVD with ESR patcher. Even if U go want to go legit get a slim which are tiny and get your favorite games used for like 5 bucks a piece. To me emulation and classic gaming is mostly appealing on handhelds as I have replayed quite a few PS1 RPGs on the psp and platform classics on NDS. There is so much great content from this generations consoles that I have yet to play I just don’t have time to be messing with old PS2 titles. I do like when they do HD updates though of games that stand the test of time like ICO…..please ifU never played this game get the PS3 version and play it. Top 5 game of all time IMO
-
Wow.. I will be impressed if they bringing back PS2 emulation to PS3 and also maybe to Vita for the first time. Both PS3 and Vita is a powerful Console.
-
Look at your quad core tablet…vita is as strong as that ..I hate when people make the vita out to be some kind of Uber Handheld
-
Actually U are a little wrong on that…..vita also has a quad core GPU in addition to quad core CPU. I would say U would have a hard time finding a tablet with the polygon power of a Vita. That’s why 3d games on y iPad 2 look like Ps2 level grafx and Vita looks like ps3 level. If u don’t own a vita Umshould really get a look at the Drake or other top titles and U will see it blows away anything U will see on current tablets including the ipad3 which has awesome resolution but still nowhere near the GPU power of a vita…..BWT I own all these devices so I am not speaking as a fanboy bit someone who has seen and played what is available!

-
but if you can download a ps2 emulator on your pc then why cant you just download a ps2 emulator for the ps3 ??
-
wtf????? why arent they doing PS2 emulation for PSV? dont you tell me, PS Vita it’s still not powerful enough to do that.
-
Did you read the article? He talks about how the PS2 architecture is tricky and this iOS why it is so hard to emulate. Even on PC it takes a pretty beefy PC to emulate ps2 games at full speed. This is one reason why the PS2 had such a long life. Some of the last Ps2 games looked great like GOW and FF12. Sure they were only 480p but they looked almost as good as x360 early titles.
I am pretty sure there will never be an open ps2 emulator on vita unless it gets hacked. Most likely we will just see some ps2 classics like MGS series that they can get running well enough.

My Ps3 Plays PS2 games, I’m surprised its still going actually

Apparently we're on twitter too
