Hopefully somebody can reverse-engineer their findings into code towards PCSX2, or a new emulator, since it's x86 architecture.
Anything would be better than P(HAK)CSX2
They used to have adware in their installers. The devs of course justify it with the typical excuses:
"You Can Choose To Not Install It™"
"It's Optional™"
etc.
To be honest, I've had nothing but trouble with PS2 emulation over the past few years; it's just a big pain for me.
An official emulator from Sony wouldn't be as problematic considering they know their own hardware inside and out.
I've only experienced graphical bugs. The software renderer may be better but it runs slowly for me.
Speedhacks may "speed up" the game but they lower the ingame framerate so it looks
worse.
Async mix makes the sound more tolerable, though.
You literally just put the bios into the PCSX2 folder, configure the buttons, choose the iso, start the game, and you're done.
It's really not that hard. lol
If your GPU doesn't have DX9/10/11 support then it's time to upgrade. Don't blame the emulator for your shitty PC. (
if you have one)
But to be fair Dolphin runs MUCH better so it goes to show which one has made more progress.

I wouldn't ever expect it to improve significantly. I have faith in
Play! though.
It doesn't need the BIOS and has made lots of progress. It's actually starting to boot up some games now.
And I've had nothing but great successes (except for one of many emulated games, Valkyrie Profile 2). I was able to play Persona 4 in HD before Persona 4 Golden was even a thing. I was able to play games that I couldn't on my PS2 because my dog chewed them up. I'm not one of those people who blindly stick to their nostalgia. If I see an objectively better method of doing something, I will. I doubt the PS4's emulation of PS2 games will be any better than PCSX2, and like others are saying, it probably won't accept discs, at least until hackers get their hands on it.
I have a different reason to have consoles.
If I find a glitch in game with an emulator I'll try to replicate it on the actual hardware to make sure it's not an emulation glitch and vice versa.
And PCSX2 (or Dolphin) in 1080p sure as hell beats 480i (or 480p) on a CRT. There's no competition.
The "it looks better" excuse is only valid if the game is sprite based.
