WHY can't ps3 slim play p2 games? Money or technical issues?

Greed. Nothing else. Not having them gives them a reason to milk old games, pain and simple.

I remember reading that the ps3, actually had a ps2 software emu, used by games like GoW

 

Right! and wrong! It's not the sound processor, it's the I/O processor.

 

This is one of the main reasons:

When sony removed the ps2 functionality from ps3, I wasn't surprised at all. The emulation quality was terrible. I think they removed it simply because it wasn't up to their standards.

Heres an old video showing comparisons between a real ps2 and ps3 emulating a ps2:

Like the video description says, that problem was fixed 4 years ago with a firmware update.

 

Yeah, Ps2 playback while not amazing is not that bad anymore (my PS3 is HW BC and I spend half my time playing ps2 games on it).

 

Didn't see the description, just remembered the video pretty vividly and googled, sorry bout that.

For the models that technically have the ps2 hardware in them, I'm sure its just a line of code that was removed to disable it. If cfw can bring this capability back I think that would be an amazing win for the modding scene (and good publicity at least)

Here is another video that doesn't look anywhere near as bad. Why? No idea.

This one too.

To be fair I always found the PS1 to look like utter trash when it was new (unless played through Bleem! for the Dreamcast or ePSXe) and the PS2 was ok except in heavy need of FSAA.

 

Umm. what??? :lol:

Sony never took BC out of systems that had the hardware. My PS3 still plays PS2 games just fine. So do 80GB PS3 with partial HW. Not sure what the hell you're thinking on this one.

 

Quoting from Consumed in a previous post in this thread, read before hating on someones post please

"Allegedly. All Japanese 60GB and 20GB units have full PS2 hardware inside them, as does the 60GB launch US model. The 60GB European model doesn't though, due to costs the Euro unit was revised and PS2 implementation is done under emulation. Now is gets confusing because in Europe at least when the 40GB and 80GB models were released there was supposedly no PS2 emulation software on board at all but whereas the 40GB won't play anything the 80GB will play some titles, for a while there was even a patch on the PSN store that facilitated such a thing. Whether it's still there or not I don't know but for a while it most definitely was. In the case of slims though it seems with the exception of Singstar(?) you'll never get any PS2 software running"

The piece is so unsure about so many things.
USA 20GB & 60GB units both are full PS2 HW. Japan 20GB & 60GB units are also full PS2 HW.

Europe 60GB units are Partial emulation (not full emulation). The hardware contains a HW PS2 GS. The EE is delt with by software emulation. This software emulator is contained in all Fat PS3 unit firmwares (unsure on slim, i think maybe).

USA 80GB units are based on European's 60GB unit. From there the 40GB units in all region have no PS2 HW what so ever.

 

Some games run perfectly with the software CPU emulation. Some don't work at all. The compatibility is pretty good though - definitely not terrible. The video you are showing is of really early firmware, most of the issues in that video were fixed in a couple of updates.

Obviously, the first models had the best (almost perfect) emulation. It wasn't really emulation on those, though.

In no instances was the emulation REMOVED from consoles. It was just not included in new models when the PS2 GPU was removed.

 

Don't say "almost perfect". While it might have been good, even PS2 Slims have PS2 game compatibility issues and I'm sure the PS3's with EE+GS have some issues too. Then the GS only PS3s with a good bit more issues. Perfect is very hard to live up to in emulation.

 

That's a problem that plagued many PS2 & PS1 systems since the internals are constantly revised.

Back when I did PS1 games after Ps2 was out we where required by sony to make sure our game ran on 2 main variations of PS1 & was compatible with Ps2 hw. We did run into bugs that only existed when running on a PS2 due to the way certain things function slightly different.

=(

 

It's around 15 games or something that don't work properly on the EE+GS combined die. And most of those are slight issues, like longer save times and sound issues on FMV.

Here is a list: http://en.wikipedia.org/wiki/List_of_PlayStation_games_incompatible_with_PlayStation_2

Almost perfect I think is fair. Aren't there 1000+ games for the PS2?

Of course, the software emulated EE mode 2 PS3 is no where near the same compatibility.

 

But you have to realize the decreased PS1 compatibility over the fat units. Plus for PS2 those are just the games that are known to have issues. There may be more games that have issues than are listed. Really in general I recommend anyone against using backwards compatibility of the Playstation unless there is no other choice. The Wii and the Gameboy didn't have near as many issues though there are some slight issues I recall.

 

Ah gameboy..!

I remember that my GB gamepak Prehistorik Man, by Titus (RIP) had audio issues when played on a GBC. However, on a GBA it worked like a champ!
