Does the 60GB PS3 run PS2 Classics through hardware or software emulation?

I've never purchased a PS2 Classic off of PSN until the other night because I have pretty much every PS2 game that I want in physical form along with a fully backwards-compatible 60GB PS3. As most of you probably know, the 60GB PS3 has the PS2's hardware included inside, so no emulation is used when loading up a PS2 disc.

I'm wondering if that's the case when playing a PS2 Classic off the HDD, however. For all other models of the PS3, PS2 Classics run via a software-emulated solution given the complete removal of the PS2 hardware. Most of the time this doesn't have any impact on the performance of PS2 Classic games downloaded from PSN, but I've heard of one exception that piqued my interest: Odin Sphere.


From what I've seen claimed both on GAF and elsewhere, people have reported that the PS2 Classic version of Odin Sphere doesn't suffer from the egregious slowdown of the original disc release. Some people purport that this is because it's actually the PAL version ISO, and in that version the slowdown was mostly fixed. I'm pretty sure this isn't the case, however, because the PS2 Classic version that I got from PSN just last night features the word bubbles that were only present in the NTSC release. They were replaced by subtitles in the PAL versions.

I previously owned an 80GB partially backwards-compatible PS3, which used a hybrid of hardware and software emulation. I noticed that the disc version of Odin Sphere ran perfectly on that machine, with zero slowdown and super-quick load times. I suspect that the game simply benefits from running off of an HDD with software emulation probably helping even further. So, I theorize that this is why people are claiming that the software-emulated PS2 Classic version of Odin Sphere runs much better than the original release.

BUT when loading it up last night expecting to be greeted to a flawlessly-running version of Odin Sphere, I noticed slowdown typical to the original release in the first few minutes. What is happening here? Do 60GB PS3's default to using their internal PS2 hardware for downloaded PS2 Classic games? I thought that it used software emulation for these regardless of PS3 model, but now I'm not so sure. People were swearing that the slowdown was gone in Odin Sphere, but it's definitely not on my PS3.

Any insight into this matter would be greatly appreciated. I want to figure out whether or not I just wasted $10 double-dipping on a PS2 game that runs exactly the same as my physical copy.

60GB is on hardware.

80GB uses software.

Edit: Disregard what I said. Didn't realize this was for a digital version.

Only the first 60 GB models USA/JP it's totally hardware. EU nevers seen this model. 60 GB pal was an hybrid hardware (gsx processor) and software for the EE.

I believe it is a combination of software and hardware...

" The European 60GB model (CECHC), the South Korean and North American CECHE 80GB model excludes the PlayStation 2 "Emotion Engine" CPU chip with it being replaced by an emulated version via the Cell Broadband Engine. However, it retains the "Graphics Synthesizer" GPU resulting in a hybrid hardware and software emulation"

As someone says above the US 20 and 60 GBs had both.

For physical discs only. All classics from PSN run software.

If you want the improvements that a 60GB PS3 is supposed to give you, you've gotta find those physical disc versions.

guy's the OP is asking specifically about the downloadable ps2 classics
and i'd be willing to bet that those do NOT run using the built in BC, but rather they just run in a software emulator that comes packaged in with the game. it's essentially a ps3 game

Ah, you know what. I found the answer thanks to Digital Foundry.
Digital Foundry said:
Regardless, we delved into our PS2 game collection, dug out some titles available on the PlayStation Store and ran them on three different PlayStation 3s - our launch debugging station (which runs any PS2 game from any region under full hardware back-compat), an EU launch unit with the hardware graphics synthesizer and emulated Emotion Engine, and finally, a newer PS3 with no hardware support for the older console at all. The latter turned out not to be required at all, so it was quickly disposed of: even if you're running a launch NTSC unit with all the original PS2 hardware contained therein, the PSN downloads still run completely under software emulation.

So maybe I'll have to play a little further into Odin Sphere and see if the performance really is improved on some of the more intense boss fights. I only played a few standard levels to test it out, and I noticed little dips here and there. If I get slowdown on the boss fights, then I don't know what is going on. Maybe everyone claiming that performance was improved in the PSN version lives in Europe and is playing the PAL release in digital form.

Sorry about that guys. Didn't realize PS2 classics was the brand name of the digital releases.
