PS3 is 90% Backward Compatible to PS2?

With PS3 finally gettging some good exclusivies (Ratchet & Clank Future and Uncharted: Drake's Fortune) I bit a bullet and bought 80GB console at K-Mart (thanks to their 20% off coupon). Since I never owned PS2, I thought that I would pick up a classic PS2 title here and there in between new worthy PS3 releases. Sony's statement that their software emulation provides 90% backward compatibility soothed me - if I find 1 title out of 10 that I would want to play but could not, so be it - no biggie I thought.
So, skipping forward, I played Ratchet & Clank Future and that game is very very good - great graphics, memorable story, good humor, excellent gameplay. I looked at PS2 for previous titles in the franchise and found at least 4 games - each and everyone with excellent reviews from users. So, just in case, I decided to check what's the BC status of these games in emulation mode. I mean, they were all hits, so the logic would dictate that if any games are backward compatible these must be. And what do I find out? None of these games, according to Sony's Compatible Status Support page are playable on PS3@!
  • Ratchet & Clank - Throughout gameplay, the title performs at a significantly slower than normal performance speed.
  • Ratchet & Clank: Going Commando - Throughout gameplay, the title performs at a significantly slower than normal performance speed.
  • Ratchet & Clank: Up Your Arsenal - At various points throughout gameplay, the title may perform at a significantly slower than normal performance speed; the title hangs.
  • Ratchet: Deadlocked - Throughout gameplay, the title runs at a significantly slower then normal performance speed; the title hangs; various graphics appear corrupted.

Wow!
I sincerely wonder, how did Sony come up with 90% BC statement? Do they consider games that have corrupted graphics, hang at some points and perform like in slow motion to be Backward Compatible? Because, if they don't, the simple statistics analysis would show that chances of me finding 4 games in a row that get into that elusive 10% no-BC list are astronomical and I should probably rush to the nearest casino before my luck runs out.

I am not any kind of Sony boy (whatever the epithet may be inserted there) - I just really want to find out if Sony is pushing some serious marketing BS our way or there is something else going on that I am not aware of.

Your personal experience is very welcomed.

I bet I could play those games with no problems on my 60GB PS3. :) The 80GB PS3 definitely has <90% BC (PS2 wise).

PS3 BC database - 60 GB model:

Ratchet & Clank
Description: No major problems for this title.

Ratchet & Clank: Going Commando
Ratchet & Clank: Going Commando (Greatest Hits)
Description: No major problems for this title.

Ratchet & Clank: Up Your Arsenal
Ratchet & Clank: Up Your Arsenal (Greatest Hits)
Description: No major problems for this title.

Ratchet: Deadlocked
Ratchet: Deadlocked (Greatest Hits)
Description: No major problems for this title.

People were warned that the 80GB had lesser BC, this appears to be one of the cases where it matters.

I mean, they were all hits, so the logic would dictate that if any games are backward compatible these must be.

Not really. IIRC xbox uses miniports custom-written for each game on top of an emulation library, so they tweak it game by game and it took well over a year for some popular titles other than Halo to appear. No miniport, then you can't even try to play the game.

The PS3 uses true general-purpose emulation that you can try with any PS2 game including new releases (without waiting for new profiles / miniports) but there's no guarantee that the emulation will work. The 60 GB uses GS + EE chips from a PS2 slim to help the emulation, but the 80 GB only includes the GS chip so must do much more in software.

It's typical marketing bs. Before the 360 was even released Microsoft promised 100% backwards compatibility with all Xbox games. Then Allard comes out and says, customers don't care about backwards compatibility, so we're not gonna dick with it.

Software emulation is never perfect, if there's no built in hardware it's guaranteed that many games either won't work at all, or will have several performance/graphical issues.

I've never seen 90% quoted, but I have seen around 80%. At 80%, the probability of 4 independent games not working is 0.2^4 or 0.16%. The important point is you did not choose 4 independent games. You chose 4 games from the same developer likely using the same engine. Therefore, that minuscule statistical probability came from an invalid assumption, and you aren't as lucky as you thought.

All of this BC stuff with the various PS3s, especially the new 40GB model that doesn't offer any BC, makes me wonder if it's a ploy by Sony to get people to spend even more money on the new, new redesigned PS2 that's to be available in 1Q08.

I don't know why they removed the EE chip from the 80GB/40GB PS3's. I realize the reason...$$.....but it was only a few bucks, and made the system so much better. Hell, the primary reason I bought a PS3 (20gb) over a 360 is for backwards compatibility, since I had Gamecube last round.

PSA - God of War works just fine on 80gb PS3 and I'm loving it.

Is it 1st of 2nd God of War? PS2 compatability status shows that first one is not fully supported.

As for your question, I doubt that Xbox guitar wuold work on PS3. The Guiar is nothing more then a glorified controller for the respective console and they are not compatible.

Is it just me, or did the latest update make PS2 games overscan badly?

FFXII is almost unplayable now in 16:9 because the cursor gets cut off on the left hand menu.

Snagged myself a 60GB model with the full hardware emulation a few months ago when I heard they were phasing out the Emotion chip. I never really played any PS2 games, and there are a boatload I want to play, so BC for me was a requirement, and 100% with the Emotion chip as opposed to some random percentage with software based emulation was essential.

All the game has to do is run; it doesn't have to run correctly. Sony probably considers all those titles you listed as backwards compatible.

Lots of people have been complaining, hopefully there will be a small fix.
