Breh. You can run PS2 games on an off the shelf budget PC from years ago. I know because I've done it. There's absolutely nothing stopping PS4 from playing PS2 games. You made that up.
And you can split hair about "stable" or "unstable" but ALL emulators take time to get right. And that's because the people working on them usually don't have all or really any of the important files or hardware so they have to reverse engineer it. If random computer programers can do it, then Sony definitely can.
As stated above all emulators are unstable until they are stable. Cell is more complicated, with even less info cause Sony and everybody else threw it in the bushes where it belongs.
And even with that, people were still able to reverse engineer the shyt and get it running. There's updates all the time about more games they get working correctly. If they can make an "unstable" emulator then Sony can damn well make a "stable" one.
Yeah fanboys on forums
Don't need to be an engineer to recognize bullshyt when I hear it.
You don't have any facts.
And earlier you said PS2 can't be done. Now you changed your mind
