PlayStation 5 ROM keys may be out in the wild, opening new possibilities for emulation

[Burty117]

I have flower on PS3, and also bought it on Steam. Journey is also available on Steam. I have that too.
In fact many previous PS3 games are now legit PC purchases, and usually low price. Even Uncharted.

Unfortunately, Uncharted 1,2,& 3 are stuck on PS3 with a remaster collection on PS4, No PC ports yet. Uncharted 4 & Lost Legacy do have offcial releases though, even though Lost Legacy was probably my least favourite out of the bunch.

Oh first thing on my list is kraken, then you have io modification, fp pipes, coherency engine, pssr. I'm sure if you get deeper you'd find more hardware level modification, which actually resulting in sillicone changes. Kraken is part of custom io SOC. I'm sure there are much more changes, all the audio stuff is hardware as well and is in soc.

I don’t believe any of those things would result in changes to the x86 instruction set. There is nothing I have ever seen to suggest they added any custom instructions.

Kraken, FP pipes, pssr etc would all be implemented / emulated in software but this is unlikely to be a big issue if the actual game is running natively on the pc.

As I said before the vast majority of work is writing the proton style translation layer. A huge job to be sure but performance is not likely to be the biggest challenge.

Its not change to x86 insyruction set. It is not even a change to x64 instruction set. Those are many changes to the hardware instructions, which needs to have software emulation in place and will slow down emulation a lot. Same, as with ps4, where you need significantly stronger pc to emulate old ps4 apu, but potentially even more difficult with ps5 apu.

Especially, there is really little point to do all this for like 3 games only.

"Ah, got it! Yeah, it’s a shame the first three haven’t made it to PC yet. I’ve heard the PS4 remaster collection is really good though. I actually enjoyed Lost Legacy more than I expected, but I get why it might not be everyone’s favorite!"

Ps5 cpu have its own microcode and dedicated instructions set. Sure, 95 pct of instructions are taken directly from amd, but many other ones ps5 specific has been implemented as well.

Its not change to x86 insyruction set. It is not even a change to x64 instruction set.

So which is it?

So which is it?

..... Dedicated hardware instructions set? You know, it is possible to have hardware decoders like kraken, hardware ASICS, specialised instructions to handle single memory pool and whatever Cerny decided to go with, without altering x86 or x64 specification. There are much more instruction standards modern cpus handle aside of those two... Sse, avx, fma3, adx, ... many more. And ps5 have some specific ones added on top of thst.

I feel like every answer you give is wild speculation or obfuscation. Avx instructions for example are simply part of x86, why single them out?

I’m willing to be proven wrong but I see no evidence that ps5 has anything other than a standard amd x86 cpu. Of course you can have extra hardware for compression etc and that would likely need to be emulated but if the cpu can run the core game (via a proton style translation layer) Then it simplifies the problem a great deal and makes performance less of an issue.

Woops, yes indeed you are correct. At least I have the original boxed Uncharted for PS3.

Anyway, thanks for correcting my error.

I recently played through 1,2 & 3 on the PS3, honestly, it's impressive how well they hold up, the first game did have some frame rate issues but 2/3? Really impressive what they got out of the PS3.
