Another Sony Interactive Entertainment Backwards Compatibility patent goes public
- Thread starter RevengeTaken
- Start date
Of course it doesnt mean that's how it'll be in the end, but I feel like they're going for a regular bc without any possible improvement for older titles.
If I'm understanding the OP right, no. OG PS3s had actual PS2 hardware in them to do BC, separate from the Cell/RSX, while this seems to be running BC by using the same CPU/GPU as PS5 games, but in an altered state.
If we're talking the OG 2006 PS3 Model. I don't believe so. If I remember there was a legit PS2 inside of the PS3. The emotion engine was actually inside along with the Cell and RSX chipsets. PS1 games might've worked in a similar way on the PS3, but I think that might've just been pulling from the software emulation from PS1 Classics on the Store.
I just want enhanced BC out of the gate, force games to look prettier automatically.
Later PS3 models had software emulation with PS2 titles and no actual PS2 hardware inside.
PS5 will definitely be backwards compatible with PS4. Considering the PS3 had an the Emotion Engine in it to do BC for PS2 games, does this mean that PS4/PS5 need it as well to do PS2 BC or they hadn't figure out how to do BC for PS2 during PS3s time and skipped out on it altogether for PS4 to cut costs?
And if they did indeed figure out how to do BC, how far back are we going? Will it be PS4/PS3/PS2/PS1, PS4/PS3/PS2 or PS4/PS2/PS1. If they get PS3 in there, can someone please explain to me how they'll be able to make that possible?

it's simply stating that IF and OR commands.
So at the top, you see 201 starts. That means if you booted up your game ((Physical/Digital... which is not stating.)) then it goes with this question > is your game a PS4 game or a PS1,2,3?
- If it's PS4 will go for NEW --> which will run the system regularly.
- If it's PS1,2,3 will go for OLD which is Legacy CPU--> which your PS4 might or not will change the User interface? I think it's the same with the WiiU where you choose a Wii game which takes you into a different dashboard.
- If you click legacy, it will take you into a 4 options. I think these are for an enhancement you can make? Such as resolution and different enhancements. Or without any upgrades.
correct me if I am wrong.
Agree on this.
And hopefully it will improve the games too if it's possible...
OG 60GB/20GB PS3: FULL PS2 CPU/GPU
NTSC 80GB / PAL 60-80GB or whatever (PAL regions got the PS3 much later): Partial PS2 Hardware / Software Emulation (pretty sure it was the Graphics Synthesizer that was left in since the Cell could emulate the Emotion Engine by that time. The PS2 was able to do crazy fillrate that last gen's consoles were not able to do)
Every PS3 afterward starting with 40GB Fat to Super Slim: All software emulation only

I think we can expect pro level BC, but it would suck if the performance is capped to pro level.
Isn't this what they implemented on Pro? Sure it's very likely pro was a test for BC and that they will bring it to PS5.
Since the patent is about the cpu crippling itself to match the previous cpu in order to run older games it's clear that just being x86 does not ensure BC.
Yeah, the corporation that have had BC in all but 1 of their consoles is against it.
The claims are the only bit the patent actually lays claim to. When you drill down into that, the core claim seems to be this:
Which is rather more specific, as a claim should be. Most everything else is just context and broader explanation...not everything described in that is part of the claim.
Yeah. Based on the timing aswell, this very likely is part of the same family of patents that were Pro related.
Now I fully expect them to be doing similar things, and extensions of them, for PS5 BC with PS4. But the breathless articles we see around this patents, heralding the possibility of PS1/PS2/PS3 BC, should cool their jets IMO.
Yeah. Obviously it helps a lot, but if you let devs go very low level with the CPU, and.or want really reliable/precise behaviour, to avoid potential inconsistencies and bugs appearing in software on the newer cpu (e.g. race conditions popping up because code finishes faster or out of order on newer cpus), you probably want to layer in some changes to make the environment as close as possible to the original.
Because they decided not to put BC in the PS4 they were obviously going to say that
They're not going to come out and say "yeah we love BC it's just that we tried and it would be too costly to get it running on PS4"
They will always try and spin it in a positive light
They did the same when they were originally not happy with cross play, they didn't state the real reason, as it would be bad PR, so they used some corporate bullshit "protect the kids" or "PS is the best place to play" nonsense
You can't really take what any corporation says seriously
Like all the other Sony patents that have been posted in the last year or two, it states the (much earlier) date right at the top of the patent it refers to (July 27th 2015).
