I know that a PS2 emulator on Xbox isn't possible, but I just want to know what the technical reason is that it isn't possible.

Cos you would need a MUCH faster processor to emulate the ps2 hardware AND run the games!

Actually, I'm under the impression that one would be possible, if we had enough raw data on the PS2 and Xbox, with enough work. That'd probably involve stealing literally *tons* of copyrighted info from MS and Sony, and a lot of work. Eventually with all of that, it might be doable, but quite slow running, in the end.
Or you could stop being such a cheap-ass and spend the $180 for a real one.

Yes, you just do that .
I think that should be way faster than waiting/hoping for a PS2 emu in the future.

what they are saying is in theory it is possible... but not worth the time or effort someone would have to put into one.

OK, the faster system thing is ok.
Let me explain it. A PS2 has a processor of 300MHZ (128-bit), plus it has lot of RAM, an individual GPU, its RAM and many other complicated stuff. Plus, the whole processor-core of the PSX is also included on the PS2. So, determining what is there inside the PS2's heart (instructions, that is) would be difficult. Now compare the PS2 specs with XBOX. XBOX has 766 MHz processor, 64 MB Ram and specs that are just double than the PS2. And remember that the 90 MHz N64 is hard to emulate on a 866 MHz processor of a PC, (though its somehow easy to emulate it on the 766 MHz XBOX).
Also, the core of the PS2 processor and the XBOX P3 processor is very different. So the whole idea of emulating PS2 on XBOX seems a dream.
even XBOX games wont run on XBOX2, due to a similiar reason. MS is planning to use AMD processor for XBOX2, that have different instructions code than the XBOX's P3. Make MS realise what a grave mistake it is doing by signing the onliine petetion at http://www.petitiononline.com/xbox2/petition.html
Hey, dont forget to do that before its too late, and do explain to MS, why backward-compatibility is necessary!

Or you could go fuck yourself with your unhelpful response. I acutally have no interest in buying or playing one. I traded my Xbox for my brothers PS2 for awhile and out of having it for a month I played it about 5 hours. I'm just curious about the why's of it.

Thanks for you response.

*edit*
A newbie was more helpful than a Senior member. Hmmm.

Since Xbox is basically a PC, read this article, and you may understand why its impossible for the XBox to emulate a PS2:

http://www.arstechnica.com/cpu/2q00/ps2/ps2vspc-1.html

the reason i like emulation on the xbox is that most of the emulators emulate obsolite systems.
n64 is nearly in that categry. saying that though i like the gba emus so i don't know what i'm saying as usual.

hahah browll. I love it when you (as in myself, not you personally) start typing or saying something with a good point in mind, then get right near the end and realise what you've just finsihed saying contradicts what you initially started out saying, or trying to prove. Or you find your end result is the same as the start. Either way, you've made no progress, but it was a fun journey.

(If THIS makes any sense, lol

I like how a newbie is getting all flustered about a senior blowing them off when the thing hes suggesting is prominently pinned on the front page.

Also webmaster seems to have some kind of insider information. I'd like to know how you know for a fact what CPU M$ is doing when all the analyists are still speculating.

Crap. I wasn't trying to be an ass, I've seen Hoppy here long enough that I figured he'd read the pinned thread.
On top of that, most people ask about PS2 emulators, wanting to play one. If you're just curious, I guess that's cool...

No harm, no foul bro.

Have one on me

There's a PS2 emulator built into 007:Agent Under Fire!

You need a BIOS with the EjectFix patch in order to access it.

Here's what you do...
Boot your Xbox (modded with EvoX M7EjectFix, for example) with 007:AUF in the drive
Wait for the EA logo (white screen, whizz...whizz...ding!)
Eject the disc
Voila! Pretty damned accurate, too!!!

lol

I take it you've tried it, then?

Okies in regards to the whole hoopla with MS changing cpus for the XBox2...
If they use an AMD chip similar to what we use at home it will run exactly the same software. The instruction sets that amd and intel us on their 32bit cpus are identical give or take sse2(not sure about this one).. Its how they execute the intructions that is differant. The problem we run into is if they use an IBM chip wich will no doubt be a PPC chip basicly tossing compatibility out the window, or less likley but possible would be a cell based chip, wich may have enough power to use a software layer to emulate xbox 1, depending on the power of the new chip. I for one would love to see an amd x86 based chip inside as intel dosnt seem to willing to share the p4 for any such purpose or more likley wants WAY to much coin to licence the tech.
So dont go freaking out untill we get some details... Lookin at the success of the ps2 i find it hard to belive that MS would ignore one of the main selling points the PS2 offered in the earlygoing, You could play your good ps1 games while you waited for good ps2 games
relax its not worth freaking out about without more info...

CODE

A PS2 has a processor of 300MHZ (128-bit), plus it has lot of RAM

If I remember right a ps2 has around 32mb total system ram since when is that alot?

It's a lot when Sony refer to it as 256 megabits (or 256 mega, to be REALLY vague)

Look at the Sony "8 meg" memory cards, that's an eighth of the size of the Xbox "8 meg" ones, 'cos the Xbox ones are 8 megaBYTES!

Even the old Neo Geos did the same...

QUOTE (Boot-up @ Neo Geo arcade machine)

NEO GEO Max 330 mega Pro Gear Spec

That's only 41.25 megabytes. Okay, so it was a lot back then, but a con nevertheless.

XBox2 is planned to use an IBM processor, not AMD.

No one is sure if it will be based on the (dead) Cyrix line, PowerPC, or one of the many others IBM makes... But unless it is the Cyrix, it uses a different instruction set!

Morden.

VIA owns the rights to all of the Cyrix stuff sans the MediaGX-derived stuff which is owned by National Semiconductor, so that possibility is out the window.

I'd say a PPC-based processor is the most likely possibility.

XBox 2 or whatever it's going to be called will probalby have backwards compatibility because the PS3 does and if the Xbox 2 doesn't then it might be in trouble. The only advantage the xbox has right now is more power.

No, ps2 memory cards hold 8 megabytes of content.
Sony uses standard units when talking about things (bus being in bits, same for gprs, space in bytes, etc.) so please stop with this trolling.

And sorry to cramp people's dreams, but even if you had a god programmer, the xbox cpu doesn't have the required bandwidth alone to emulate the ps2, let alone any of the other issues. Not to mention the ps2 has the equiv of 3 sse units on crack running (r5900 mm extensions, vu0, vu1). You can issue 12 32-bit ops in a cycle on the ps2 pretty easily, try that on the xbox.

The xbox cannot even begin to emulate ps2 at a resonable speed, ever, without hardware mods, and then it would be the mod emulating the ps2 not the xbox.

Edit: Lets add some more fun...the ps2 has 96 128-bit, 35 32-bit, and 32 16-bit registers. Yep...lets see how well you emulate that on ix86, can anyone say memory outside of the cpu will be required, and yes that means that ~1GB/s link the cpu has is going to get saturated nice and fast. (That's just between the r5900, r3000a, vu0, and vu1)

chech the tech chat, if they can figure out how to swap in a 1400 cpu and double the bus speed ala friendtech's box it MIGHT be possible, but not unless someone gets a working pc version first

i think this will be closed tonite

fuck the ps2 it sucks big fat cocks anyway , go and buy one if you wanna play ps2 games

ah that whole megaBYTE and megaBIT thing is pretty gay

man Ps2 sucks anyway.....I would take Ps1 over it any day

Hell's yeah!

If one of the main members of the PS2 development team wrote an emulator that was 100% efficient, then it could be ported to the xbox, no problem.

Chances of this happening: 1,000,000,000,000,000,000,000,000 to 1

Go buy a PS2...

Man, this is the kind of reply one should get in a forum.
Latest nes about cpu and chips: - MS is planning to develop its own cpu and video chips. Search the net for the news details.
About backward compatibility: - MS cant afford to release xbox2 without backward compatibility. But who knows, MS is quite dreadful sometimes.
PS2's power: - All you xbox fans, you've never ever tried a ps2. I own a ps2 and an xbox both. But Its quite dreadful to change consoles everytime, thet is why someone rquires an emu. So you see, asking for a ps2 emu means playing the ps2 exclusive games, cause the others are surely going to be released for the xbox. Isnt it? One thing I need to tell you is that, PS2 emu is, in some ways, superiour to xbox. Now, I am not going against all of you, but I have observed that for systems like NES, Atari and Genesis etc., PS2 emu is simple, just scroll and select. No issues like installing etc. Just burn the binary file onto a cd. But this simplicity is again due to the fact that the PS2 is not as powerful as XBOX. In a nutshell, Buying a PS2 is not the solution.

i don't think it is impossible.it is very hard maybe but not impossible.
Instead of emulating all the console probably translating the operation form ps2 cpre to p3 core is possible.also for the custom graphic chip someone should create a wrapper.
like plugin for epsxe that render psx graphic on geforce cards

I think MS can afford anything they want. Would it be a smart business move? No =P

the xbox 2 isnt gonna play xbox1 games for the simple reason that adding the required hardware to allow this would bump up the cost of the xbox2 console, not everyone wants such a feature and if they did then they would buy an xbox1, at a time when the xbox2 is launched the rrp of an xbox wil be very low.


Its time we forgot about a PS2 emulator, i cant believe anyone really things its possible, its been said endless times that there simply isnt enought power to do it, it cant emulate the PS1 perfectly so what chance do we have of emulating its big brother thats about 10x more powerful.
