| | I get that the x86 architecture is huge so even though it is well documented it would be difficult to emulate, but since PCs are already x86 anyway, why is there even a need to? Shouldn't all that needs to be emulated is the Orbis OS or whatever? And the Orbis OS is based on FreeBSD which is open source, so it would seem to me that this should be very easy to sort out if people would just approach this the easy way instead of trying to emulate an entire architecture which there is no need to do because PC is already that architecture anyway. And if I'm wrong then please tell me the reason why I'm wrong because I would like to know. | | I get that the x86 architecture is huge so even though it is well documented it would be difficult to emulate, but since PCs are already x86 anyway, why is there even a need to?

| − | ::Short answer... the x86 architecture is just the CPU. Even then there still are significant differences. The OS is just that, too - PS3 having a Linux OS was irrelevant to how easy it was to emulate. Everything else is custom down to the most basic details, and of course memory management, boot-up sequence, DRM, peripherals, graphical drivers (usually different from desktop PC versions) et caetera.
| |
| − | | |
| − | ::So the PS4 (or the OG Xbox, or the Xbox One) is NOT just a repackaged PC. Just like the Wii isn't just a Mac just because both have a PowerPC CPU architecture. It is yet another console that has yet to be figured out from scratch. Granted, cases like what you wish for, do exist, like the Ouya, which is just a lazy Android modification, or the Sega Master System and the Game Gear, or apparently Android and iOS (if only Apple wasn't sabotaging those projects and buying off devs), so much that converting games between both works. This isn't one of these cases. [[User:Dipswitch|Dipswitch]] ([[User talk:Dipswitch|talk]]) 05:55, 3 November 2017 (EDT)

| − | == CPU emulation ==
| |
| − | You would never want to "emulate" the CPU in this case. You'd just use virtualization on an x86 host. That said, you CAN emulate x86. There's nothing more to figure out. QEMU already has code to emulate a modern i7 fully in software if you wanted to. Current PCs aren't fast enough to emulate at full PS4 CPU speed, not even close, but again you would just virtualize it. Therefore, you will have to watch out for emulators claiming to be real. A good example is the [https://guidestorm.com/scam-alert/ps4-emulator/ the fake PCSX4].

| − | == About PCSX4 ==
| |
| − | | |
| − | It should be clarified somewhere why PCSX4 is not in the comparative because the page of this supposed emulator appears as the first result when searching for "PlayStation 4 emulation" in Google (this page appears in second place), which could confuse those who do not know much about it. As a curiosity, at most PCSX4 is a frontend for PSNow as I was finding out.
| |
| − | | |
| − | Regarding the other projects, Spine hasn't published anything for a year and the Reddit post is 6 months old. I don't know if the project is still active, but it could be considered to be stopped until further notice. PS4Delta has no commits since January (if within 6 months it does not have new commits or a release then it could be considered dead) and the rest have not had activity in months either but it is still early to determine their status.--[[Special:Contributions/173.245.54.78|173.245.54.78]] 03:52, 24 October 2020 (UTC)
