I know that and it's fine.  If the article had a tl;Dr version I would have seen that.  However I'd still choose to buy the handful of ps2 games I care for on psn to support Sony not second hand dealers.  There's only like 5 ps2 games total I'd rebuy. San andreas and vice city are two of them.  

I'm not saying I'd go buy them for 15 quid on psn expecially when I don't have time for them now but I'll get them eventually for the price of a pint in a flash sale / regular sale.  

Why? i buy physical wiiu and ps4 games now, the supirior format. Play them, enjoy them and in 10 years i can play however i want.

It's a slippery slope to me. Is it legal to download movies you have on VHS or Laserdisc? Or to download my pal dvds that won't play here, since I can rip them and convert them using the pc. Just because you can obtain it legally, doesn't mean it's alright to obtain it illegally.

Anyway I still turn on the ps2 now and then out of nostalgia, which is usually satisfied after 15 minutes. I was just curious to see if sticking a ps2 disc in my laptop would work, it might, just not without a few hoops.

I acknowledge that both of those scenarios aren't legal in most countries, I am not disputing that. But what is legal =/= ethical =/= moral. I personally see the case of downloading a bios for a console you had already purchased and downloading a game that is still for sale which you had not purchased as totally different things ethically, even if they are both equally illegal. There is no damage to Sony's IP by using a bios to play the games you purchased on a separate platform, if you already purchased the console of theirs with said bios.  I am alright with following laws that I agree with and not following those I don't. If I follow a law I don't agree with, usually that is because I will be reprimanded for it and the cost+risk outweighs the benefit. But I guess different strokes for different folks. 

Yeah right, and how do I throw my money at Squenix and Sony then? This doesn't make any sense.

Personally, I prefer component cables and a good ol' PS2.

Sure, the jaggies are a mile wide on my projector, but the pixels are crisp enough in 480p.

And it's a good option to have. It reminds me of am old pc game I used to play 10 years ago.  I stoll have the disc in perfect condition but instead of putting it into my laptops disc drive I just downloaded the ISO. Once you buy the product I'm good with it. 

Also, emulation is a poor way of experiencing a lot of games. Various glitches are introduced to most every game and framerates are a tricky beast if you have any of those post-processing effects going on. If you're looking for fidelity, the original hardware is your only sure bet.

An interesting article on the Mythbuster's site does a good job of explaining why even the most modern, high-end PCs struggle to perfectly reproduce the even SNES. 

By and large, most of the ROMs that run well on emulation do so because the particular emulator you're running them on has a myriad of patches designed specifically to augment the way your PC handles sticky portions of the games. If you plan on playing anything but the "top 25s" on a givn system, emulation is going to get a little messy. 

Remember, most of these classics ran on proprietary hardware, and even a boatload of RAM doesn't always mean total fidelity.

Why you should play PS2 Classics on PS4:

1: It supports the original developer and does not condone to piracy (of which every single person using these emulators is doing, regardless of deflated arguments like "I only play games I own")

2: It encourages more PS2 Classics to be released on PS4, showing that things like this are in demand and allowing PS4 users more perks like this in the future.

3: The Classics on PS4 have trophy support, giving trophy hunters an excuse to play the games again.

4: It exposes a new generation of gamer to PS2 games through advertising on the PlayStation Store, as opposed to demanding that generation do their research.

5: It's easier and more user friendly than buggy, unofficial emulators.

6: Playing at just acceptable levels require an exceptional processor, as last I checked this emulator could not tap the GPU and thus required the CPU to do all the work. This would mean that, just for the price of a processor to play at PS2 levels, you could have purchased a PS4 (or even better, a PS2 and the games you want).

7: Playing with the 4K resolutions and shrinking the display area would require an even more powerful/expensive computer, adding emphasis to point 6.

For the record, most PC gamers on this forum don't continuously take shots at console gaming. It's mostly kept contained to playful jabs here and there, however I've learned to associate your Naruto avatar with not just PC bias, but anti-PlayStation bias. I obviously can't speak for everyone, but I could do with a lot less "This is why you don't need a console" debate.

I'll stick to PS4 emulation. While it sucks it doesn't support the discs, who knows what the future of the emulator is. Maybe one day they will support discs, just not trophies for all games. I also hope they lower the prices a little, or at least have sales now and then.

More importantly, I'm like the vast majority of PC owners, and don't have a PC more powerful than even the XBO. So, even if we put the emulator on our PCs, it would run like shit. The PS4 emulator also doesn't require us downloading BIOS, which I think is technically illegal, as well as messing around with plug-ins. While I would have no problem with that, as I have set up a Sega CD emulator before, others would. There's also the fact that if you don't want to purchase games illegally, you'll be buying quite a few from Ebay, many of which are quite expensive with shipping. With the PS4 we have an easy to use interface and it looks like all games will be $9.99-$14.99, regardless of how rare they are to obtain, now.
