PS Vita Powerful enough to emulate PS2 games?

[Codestorm]

If the VITA could get as far in the game as playing that cutscene, then it's obviously playable, no?

It is a demo after all. I don't think Sony wouldn't show a demo if it wasn't playable.
------------------------

there's a big difference between emulation, and running mgs4.

That was the actual PS2 game running on the Vita.
------------------

Also you can bet that the engine running mgs4 is optimizing the hell out of the assets being drawn on screen

Again,

It is a demo after all. I don't think Sony wouldn't show a demo if it wasn't playable.

The Vita is certainly a powerhouse, but its nowhere near the ps3 in terms of power.

If it could run a PS2 game like that, I believe it isn't far from the PS3's power.

Yes, it's possible to PORT games to the vita. Emulating them however, is not even remotely possible.

Technically feasible,

No. It's not. Not even a god could get a ps2 emulator running at full speed on the vita. It could maybe manage 5 fps in a few games, but i'm not even sure about that. The vita may be much stronger than any other hand held to date, but it's still running a cheap $20 ARM cpu. It's great for a handheld, but in the grand scheme of things, it's a terrible processor. The entire purpose of the ARM architecture is low power usage, energy efficiency, and low cost. This makes it great for phones, game consoles, or other low power devices that run on battery power. But that also means it is unable to do intensive processing in any meaningful time.

If it could run a PS2 game like that, I believe it isn't far from the PS3's power.

First of all, it's not running a ps2 game, it's running a vita game, that happens to be a port of a ps3 game. Second of all, no. You're dead wrong. The ps3 can do FL operations more than 50 times faster than the vita, and even interger math should still be at least 10x faster on the ps3 than the vita, though i can't be sure about that.

I'm not saying mgs4 isn't playable on a vita, but it isn't going to look the same as it did on the ps3. The character models and environments will all have to be scaled down in resolution(texture and poly count). Post processing features, and certain shader effects may be disabled. lots of special effects that use particles systems will have less particles drawing on screen. Some of these will go largely unoticed though since the screen res on the vita will make it hard to see these changes.

if you have played uncharted for the vita, one of the things that is a good example is the far off backgrounds. Its just a simple image slapped on to low res surface. whereas in the uncharted ps3 games, an object at that same distance would probably be actual geometry.

the vita can emulate the ps2 easily it has 128 MB VRAM and the ps3 cells emulates the emotion engine in the bc models that did not have the emotion engine so it was via software also sony can easily code the engine their is even full software emulation on the ps3 slims via the cobra usb so why cant a 4-core ARM Cortex-A9 emulate the emotion engine its more then fast enough if sony code it

Oh god.

Sony would rather sell ports done by developers who spend their own money to do it. They haven't done it for the ps3, so i don't see them doing it for the vita either. I'm guessing they don't want to pour money into adding a feature that will let pirates play any ps2 game out there for free. It's just more profitable to sell ports. There's no danger in having every title they put on psn, and others they haven't, available for free. That's assuming its even possible

Anyone realize there is only one naysayer around these parts? and even with all their fancy talk I don't think they know what they are babbling about. They're gonna probably not going to be around much when they are proven wrong.

Well that's not even true, i'm just the only one willing to continue arguing with people who clearly don't have any idea what they are talking about.

Go try running a ps2 emulator on a bottom of the line 5 year old computer, and let me know how that goes. That's about what the vita is capable of.

If that very non-specific post was directed at me Youkosnake then you should know

I will be the first one to scream like a crazy fangirl if there is ps2 support for the vita

also, I'm a 3d artist who's worked with several game engines. but anyone who's run the ps2 emulator on their computer can reasonably say that its just not very likely that you would get a decent fps on the vita at all.

Yea, even my computer (16 GB RAM, 2GB graphics card, 4 core processor, the works) can barely run some of my PS2 games. It's really sad because I legit own them and tried to put them in the drive of my laptop. Even with the actual discs, the only game I got to run flawlessly was Tomb Raider: Angel of Darkness. Sadly, I don't think I will be able to play my PS2 games on the go anytime soon. Although Kingdom Hearts did run with very few problems. Only the first one though.
