Backwards compatibility is the best feature of Xbox, and I don't understand why Sony is so far behind on this
Backwards compatibility is the best feature of Xbox, and I don't understand why Sony is so far behind on this
When I got the XSX recently, it was so I can play Starfield when it comes out. That was basically the only reason. I did not realize the extensive backwards compatibility that this thing has. But since getting it, I've been playing FF13 trilogy, Fable games, Dragon Age series, Lost Odyssey, etc. Basically all games of note going all the way back to the OG Xbox will play on the latest console. Either with the original disc, or you can even purchase them online.
The point of my post is I think it's a real travesty that PlayStation doesn't do this. I don't understand it. First of all, you cannot buy most PS1-PS3 games on the digital store. You can't use the discs. The main way to get access to these games is through the top tier of PS+. But the selection is quite limited, and PS3 games in particular are streaming only.
With the selection, I want to point out that you can't even play most of the Killzone series on PS+. This is a first party title. There is absolutely no reason that Killzone shouldn't be available. Killzone 1 isn't even on there. A PS2 title that is not graphically demanding.
As for the streaming of PS3 games, maybe this was justifiable back on the PS4 because the PS3 has a unique architecture that can be difficult to emulate without performance drops. But with the capabilities of the PS5, it's not credible to claim that it can't emulate a PS3. It certainly could, if Sony wanted to assign resources to make an emulator.
I am not a fanboy of one or the other, and I probably still play more on the PS5 than my Xbox, but I think Microsoft should market their backwards compatibility superiority a lot more than they currently do.

Lots of weird incorrect answers in the comments. MS 100% has changed CPU architectures and needs to emulate old games. The 360 was basically a PowerMac.
My guess - the Xbox One’s launch catalog was trash, and MS doubled down on emulation to build it out. Then they never stopped. They kept plugging away at it, and now they have a giant asset for GamePass.
MS got a head start because they were desperate for good games in the early days on the One.f

This is the answer.
If Sony was losing the console wars, they'd be doing BC, and not MS.

Sony changed their CPU architecture every time until PS4/5. The only reason some PS3s could play PS2 games is because they had also had PS2 hardware in them. Xbox has been x86 the whole time.
-
The 360 is IBM power pc based.
The simple answer is that microsoft is a far more advanced company in terms of programming an OS, the gap shows when you compare console securities, where virtually every nintendo or sony device had software vulnerabilities, while microsoft consoles tended to need to be hardmodded

As someone who programmed drivers for nt, it's not, the reason it's easier is because they started later.
Xbox is a mature x86 windows platform, vs ps1 which is an embedded mips system.
They started with their windows directx stack and just kept with it, while ps did a random walk all over the place.
Msft also had really boring hardware, like, they started with a crappy pc, then made a crappy ppc pc, then went back to a crappy pc. The software was simplistic, while Sony made really interesting hardware designs, that turned out to be hard to program, till the ps4 when they just gave up.
Msft traditionally isn't very good at operating systems, they've just had infinite resources and infinite monkeys for 40+ years, and they've been stubborn enough to make it work somehow.

The Xbox 360 was based on the same weird, in-order PowerPC 970 derived CPU as the PS3, it just had three of them stuck together instead of one of them tied to seven weird Cell units. The TL;DR of how Xbox backwards compatibility has been achieved is that Microsoft's whole approach with the Xbox has always been to create a PC-like environment which makes porting games to or from the Xbox simpler.
The real star of the show here is the Windows NT kernel and DirectX. Microsoft's core APIs have been designed to be portable and platform-agnostic since the beginning of the NT days (of course, that isn't necessarily true of the rest of the Windows operating system we use on our PCs). Developers could still program their games mostly as though they were targeting a Windows PC using DirectX since all the same high-level APIs worked in basically the same way, just with less memory and some platform-specific optimisations to keep in mind (stuff like the 10MB of eDRAM, or that you could always assume three 3.2GHz in-order CPU cores with 2-way SMT).
Xbox 360 games on the Xbox One seem to be run through something akin to Dolphin's "Übershaders" - in this case, per-game optimised modifications of an entire Xenon GPU stack implemented in software running alongside the entire Xbox 360 operating environment in a hypervisor. This is aided by the integration of hardware-level support for certain texture and audio formats common in Xbox 360 games into the Xbox One's CPU design, similarly to how Apple's M-series SoCs integrate support for x86-style memory ordering to greatly accelerate Rosetta 2.
Microsoft's APIs for developers to target tend to be fairly platform-agnostic - see Windows CE, which could run on anything from ARM handhelds to the Hitachi SH-4 powered Sega Dreamcast. This enables developers who are mostly experienced in coding for x86 PCs running Windows to relatively easily start writing programs (or games) for other platforms using those APIs. This also has the beneficial side-effect of allowing Microsoft to, with their collective first-hand knowledge of those APIs, create compatibility layers on an x86 system that can run code targeted at a different platform.

As other noted, this is not true. The early 360 development kits were literally PowerMac towers purchased from Apple.
360 games require emulation, and MS has been slowing plugging away at expanding its emulation library for years. None of this was easy.
-
I heard that the Xbox is basically like a PC (since Microsoft is so adept at this), so backwards compatibility is natural. But what you said about x86 architecture is interesting.
-
The original Xbox, Xbox One, and S/X are all basically x86 PCs, but the 360 was basically a Power Mac. Microsoft was literally using PowerMac G5 towers as early development kits for the 360.
Supporting 360 games is pretty time consuming and requires emulation. MS has been slowly chipping away at it for years.

It's because backward compatibility would cannibalize the sales on new games. Same reason Nintendo limits releases of old games. If you have an extensive back catalog of games, then new games are less appealing.
-
Or you do what MS does. Put the old games in your subscription service. Make money with monthly fees from people who don’t have the disks or don’t have an optical drive.

The simplest and most likely reason is just because they don't have to. Playstation is leading Xbox by a lot this generation (so far, things can change) and PlayStation just has no incentive to add value to something they're already selling record numbers of. Xbox is trying to attract customers, customer playstation has left on the cutting room floor, and backwards compatibility is a way to do that.
-
There are rumors of the Switch getting a successor next year. My biggest wish is for it to be compatible with the current games, included digital purchases. Honestly, if I can import my digital library and saves I’m already sold on a switch successor
-
The hardware architecture on the PS2 and PS3 was so radically different, it effectively makes emulation impossible.
The change made in the PS4 and PS5 makes the transfer of those games relatively trivial, but attempting the replicate the now abandoned Core processor of the PS3 is the hold up there, as is the PS2 Emotion Engine.
The reason the PS3 was so expensive was including PS2 hardware to handle the backwards compatibility. They weren't going to repeat that mistake with the 4 and 5.
Meanwhile, on the Xbox side, Microsoft never had that problem.

Software emulation is very much possible. There is software for x86 and even ARM processors that emulate PS1, PS2(doesn't work great on ARM I many cases) and PS3 (x86 only currently)which work well enough. If Sony cared to they could develop their own software emulation layer to run on PS5 to run just about everything from the previous generation.
Also Microsoft had similar issues in hardware emulation because, while the original Xbox and the Xbox one were on x86, the 360 was a Power PC architecture similar in some ways to the PS3 which ran Power PC with other proprietary coprocessors. They had to develop a Power PC emulator in software to run 360 games on the Xbox one.
-
A first party solution can't work "well enough", it just has to work.
PS1 emulation at this point should be trivial, 2 and 3 is not. The first time someone puts a disc in and it doesn't work would be worse for them than not having it at all.
I think the thing holding back PS1 emulation is that once they open that door, everyone will go "What about 2 and 3?"

Xbox's Backwards Compatibility is definitely a big deal; but as someone who loves old games as a concept and has never thrown out a console, it's not as big a selling point as you would think/ hope.
I personally wanted to try some of the PS2/PS3 only games and didn't have a PS3, so I bought one used a while back. I probably only logged maybe 10 hours in it before getting completely side tracked by my backlog of modern games. And while I know that's anecdotal evidence, it really seems like the allure of classic games might not be enough of a selling point.
This is something I think Xbox had the right idea about. While BC is very useful in concept, there aren't so many classic games that would draw people away from modern games; so you only have to support those few games.
With that in mind, I think Sony could offer BC for their relevant PS2/ PS3 exclusives since they would only need to guarantee emulator performance for a much smaller number of games. I don't think it's likely for Sony to do this until they are no longer the dominant console, though, as they can make more money selling their PS3 subscription service.
From a game presentation standpoint, BC is a huge issue and I would personally love to see it happen for the PS5 (and I'd like to see it expanded to all games for the Xbox as well); but I doubt there would be much return on investment for developing the BC features, and that's the only motivation for corporations.

lol, I’d rather have the first party modern bangers Sony’s pumping out then…checks notes…literally no good first party games on my xsx since I bought it. Backwards compatibility is great, but I don’t spend $600+ on a console to play old games. I can keep my old consoles around for that or emulate.

Xbox has always doing the x86 architecture(Edit: as corrected by following comment, 360 was not.) so it's much easier to do BC. For Sony or Nintendo it's just not worth the effort until the emu is mature that they can just reap the benefit. PS5 can already play almost entire PS4 library, Anything PS2 or before can be emu pretty consistently if you are trying to get it done, then it only left PS3 in a weird place. For PS3, many good games already have a PS4/PS5 remaster games, for non-best sellers you can probably get a cheap ps3 slim with enough storage to play those left out games.(ie, PSN only Puppeteer), OR stream them like you mentioned.

No it hasn't - the 360 was PowerPC based just like Wii, WiiU and a lot of the PS3.
MS just had a lot of PC experience and games to fall back on.

Whoops, should have look it up I guess. Sorry for my old and fading memory and thanks for correction.

I wish Jet Set Radio Future was able to work on the new Xbox.

Many suspect this one has been trapped in licensing hell.
