/begin speculation

Sony has created a backend emulation activation service for PS2 non-bc consoles. User downloads game > authenticates with server to allow playing.

/end speculation

Seems far fetched but that is what i just thought now, perhaps another user pointed this out i don't know.

Not long now

Love and Sony are two terms that never go together...

Yeah, so long as the games' original source code is rewritten and recompiled for the new architecture. You can't take an existing PS2 game and rebuild it with a PS3 SDK and simply recompile it for the PS3. You have to go back to the source and rewrite quite a bit of it. On a side note, I'm still pushing the PCSX2 team to bring PCSX2 over to the PS3, but I can't seem to get much interest out of them at the moment.

Where is it though?

I've tried looking over the US and UK PSN Stores, and it does not appear to be there.

It's not interest exactly, it's that it will take them so long to rewrite those stuff that PS3's lifecyrcle would be already dead when the results will be out.
It's like a waste of time.
That's why multistructured source are for. (NullDC, mupen64, PCSX etc)
When you want to port it on a machine that doesnt have a x86 processor you don't have to go through a source code rewrite or lose heavily in performance using x86 emulation on top of the emulation...
I guess now some hobbyist developers learned their wrong by that and they try to not repeat this fault and some of them try to rewrite their code for ARM/MIPS/RISC/PPC and open the source in public so they can make the quality as near to the x86 versions (NullDC for example).

The ps2 was still selling well enough to cut it from the ps3. PS4 architecture may be completely different and may not play ps3 games in which they would have to rewrite (resale) and maybe upscale to play on the ps4. But i highly doubt they would shutdown the ps3 PSN to force people to buy the ps4 renditions of ps3 games. yes well i don't have the time to dig up the same article in every country... hell it probably said somewhere on the freakin box that "this ps3 doesn't support ps2 software" You mean all those programmers/testers at sony work for free! Cool i didn't know that . Try at least thinking just a little bit before posting next time.

LOL...oh LOL...oh LOL. Well you right I was wrong about something : I thought you couldn't sound more stupid.

1. Name one other multi billion dollar corporation that, right infront of their customers eyes, sell the same non consumable product back to them with no improvement.
2. It doesn't cost money to implement a bit of code into a ps3 that enables ps2 playback trust me. And no the programmers/testers at sony don't work for free and you know it smarta**. Is that realy the best come back you could come with? Yet you still say WE must try at least thinking before posting. Take your own advice

3.Another indication that you don't know near as much as you think you do...PS4 architecture is gna be based on cell processor which is exactly what the ps3 uses. They are gna implement 2 or more cell processors together with the ps4 read for yourself at ps4playstation4.com.ps3 games will run like a charm UNLESS sony delibrately takes BC away again.
You also say you highly doubt sony would shutdown the ps3 PSN to force people to buy the ps4 renditions of ps3 games...dude...wake up and smell the roses. YES THEY WILL. Infact I'm willing to bet money that soon after the ps4 is released psn access will be denied from a ps3 console just so they can get people to buy a ps4.remember me saying that one day.

I'm not going to waste any more time with you as all you seem to be doing is contradicting yourself with false facts one after the other and looking like a noob. Gna do something more exciting like rearange my sock draw...

Sony Patents Emotion Engine Emulation Technology For Cell Processors
By Spencer . June 29, 2009 . 3:37pm


PlayStation 3s without PS2 backwards compatibility are missing the Emotion Engine, a chip Sony designed as the PS2′s CPU. What if the PS3′s cell processor could emulate the Emotion Engine? Theoretically, all PlayStation 3s would be able to play PS2 games even if a console didn’t have the proper hardware. According to a recent patent filed by Sony Computer Entertainment in the US, Sony has the code and technology ready to do this.



There are two main ways to emulate hardware. Interpretation is when target code is decoded and converted into a language the host can understand. The other strategy is to decode and recompile programs in the host’s language.



Maybe the concept is better explained another way. Interpretation is like having someone constantly translating English to Japanese for you, non stop, twenty four hours a day wherever you go. Decoding and recompiling is like someone translating a sets of words and putting them in a dictionary you can reference.



Sony developed a way to translate instructions from an Emotion Engine chip into chunks that can be referenced.

http://www.siliconera.com/postgallery/?p_gal=40394|1















Figure 2 from the patent is a schematic drawing of how the system works. Figure 3A is a drawing of the PlayStation 2′s chipset. Figure 3B is the emotion engine. Figure 4 is where the whole story gets interesting! It’s “an example of a host system based on a cell processor that may be configured to emulate the target system.” The target is figure 3B, the Emotion Engine.



There aren’t too many reasons why Sony would want the PS3′s Cell processor to emulate the PS2′s Emotion Engine and the key one is backwards compatibility.



Perhaps, a firmware update or the new PlayStation 3 slim, which our friends at Ars Technica say is coming this fall, will utilize this technology.

The emulation patent that Sony registered is a HARDWARE based emulator patent, let's say something like a peripheral that you could buy saperatelly.
Everyone that can read the schematic can understand that it's not just an enclosed code patent inside software but there is a hardware inbetween the whole story.
Whoever is that Spencer guy (I guess he is not from Resident Evil series huh? XD) did a very nice explanation what does an Interpreter and a Decompiler do in emulation but missed the fact what the schematic shows exactly. He kind of explained exactly the opposite what this patent shows in this schematic.

Apple has been doing it for years.

It takes tons of labor hours to write the code and then test it.

you should not be calling people stupid, then posting things like "gna".

I'm not going to waste any more time with you as all you seem to be doing is contradicting yourself with false facts one after the other and looking like a noob. Gna do something more exciting like rearange my sock draw...

typical. when in doubt, call someone a "noob" and dismiss them.
