That's like saying my PC is backward compatible with every system ever made....


in many ways it is.  It is in fact techincally legal to have an emulator playing games that you have already bought on a system that you already own.  It is protected by some law about backups and stuff.

It doesnt even have to necessarily be backups...

Some old hardware allowed you to plug SNES cartridges into the PC, and some emulators can run the games straight from disc...

Old info.

In 2007 the European PS3 (and some 80GB model in US) already used the PS2 emulation to run almost all the PS2 software... there are even a compatibility list in the Sony site.

This the us games list (20GB/60GB = Hardware BC; 80GB = Software Emulation BC): http://us.playstation.com/support/compatiblestatus/index.htm

The 60 GB in Europe uses Software Emulation BC too.

No that's using actual hardware in all cases, the US 80GB model had both the CPU and GPU of the PS2 in the PS3, the EU 60GB model had the GPU and emulated the CPU.

This emulator used for classics that can run basically all games as well as the EU 60GB model is completely emulation based. It measn ALL PS3s can run PS2 software, including slims.

I'm not that stupid, everyone knows about backward compatibility consoles lol.

This is one of the reasons why i dont understand why the PS4 doesnt have backwards compatibility with the PS3. Certainly Sony has a team of programmers that can create an emulator for PS3 games... Its the way Micosoft did  with the Xbox/X360 aswell.


It's not possible to emulate the PS3 - not with a PS4 and not with a "real" gaming-rig which costs >1000$. You'd need way too much power.


I thought the PS4 was supposed to be super duper powerful. :P

You would need a console many times more powerful than a PS4 to emulate a PS3/Xbox 360, nothing exists or will exisit - even in terms of high end PC processors for at least 5 years+ to do that.

This method involves injecting a game into a single game emulator. It's how the Wii "emulated" the GameCube. Or how the PSP does it. If a game is similar enough you can inject a game and it'll run. They don't include it stand alone cause of the testing required. Plus extra cash.

The Wii never emulated the GameCube, the Wii was a GameCube (with higher clock-rates). This has nothing to do with what PS3 does.

Sorry I meant n64.

As walsufnir said, this is nothing like the Wii, it's exactly the same as the PSP though emulating PS1 games (which was opened up for hacked PSPs to run basically any PS1 game perfectly).

 

Pure software emulation using NO hardware of the original console, the Wii had Gamecube hardware in it (same CPU overclocked) and basically the same GPU overclocked with same CPU code instruction sets.

The PS2 has a completely different instructions set to the PS3 for it's CPU.

The difference in technical achievement is akin to comparing a drawing by a 2 year old and the Mona Lisa ;) Same analogy goes for BC PS3 console.

Whoever are the people involed in creating the emulator for the PS2 classics have some skills that are unmatched, to accomplish this on hardware only 1 generation ahead of the emulated console, is a feat never accomplished before.

Exactly, this is a great piece of software, I think. MS did also a good job emulating the xbox with 360 but ps2 had a very complicated architecture but somehow they could do a lot of stuff by using the spes, obviously!

Like I mentioned and was overlooked, I made a mistake and meant to say n64.

It's old info that you can now use this emulator on PS3's which didn't have this emulator? Interesting. And the compatibility search isn't really useful: It only shows the name of the game and not the state of the emulation.

The question is why Sony is not making the emulator public.

No. It's old info that every PS3 has PS2 emulation... Sony just disabled it with firmware update and/or new models but the emulation always existed.

There is nothing new in this thread.

*sigh* Ok, keep your opinion, there is no way to argue about it as it won't change anything.

It's a shame you have to hack your machine to do this, it's like a choice between PS2 games and PSN, it's hard to say which to choose when you already have a PS2 anyway.
