Hacking PS2 Emulator???

[EnigmaXtreme]

I'm just curious If a PS2 emulator could run on the Wii properly? Also can WiiSX run actual PSX discs or just isos on an SD card?

Actually now that I think of it, a Dreamcast emulator wouldnt be bad either?

 

[Dookieman]

No, Wii is not powerful enough.

 

[funnystory]

Lets do a little brainstorming here.If n64 emulators dont work good on wii,what gives you the idea that ps2 emulators will?The wii is only 2x more powerfull then the original xbox

 

[Screemer]

and the ps2 is less powerfull then the original xbox. what does that tell us? you are right! it tells us nothing. congratulations my post is as full of meat as yours is...

funnystory: Where do you get that idea from? The wii's processor runs at 729mhz and video card runs at 243mhz while the x-box ran at 733mhz and video card at 233.


The Wii has very similar hardware specs but some could say a better architecture so that the wii has the advantage, but it's by no means 2x more powerful than the original x-box. Same amount of physical ram (64mb, though wii's is GDDR3 which gives it a little bit of extra oomph) It'd be pushing it to even say 1.5x.

screemer: It was to show a point that the wii is more or less a 6th (IE last generation) console with lots of nice accessories... The PS2 was a 6th generation console, and there has yet to be a generation of of console (not handheld) that has been emulated by the same generation console. It's generally 2 generation divide between creation and emulation UNLESS the previous generation ran on very similar (though of course, improved) hardware.

hmm, doubt it XD

although i like the idea of a dreamcast emulator. i think that had similar aspects as the PS1 though which doesnt reall run all that well either lol

btw, the WiiSX emulator runs from the SD card only at the moment. its not very far in development and only a few games even work on it lol

i dont understand why N64 is so hard to emulate when we've got VC running N64 perfectly... its far weaker than the ps1 too, yet they're about level on the emulation wii scale.

never say impossible. a few months ago USB ISO loaders were impossible but now they seem very close indeed.

to those who wonder why n64 emulation is hard..... emulating a 64bit system on 32bit architecture is tough without some ingenious coding (daedalus x64 for psp) and requires much more power than the original system used.

the n64 had some very interesting architecture that in itself is hard to emulate....

please look up the differences in 32bit to 64bit architecture aswell as n64 arch to see what i mean...


an "apples to apples" comparison NEVER works in these situations. I.E. so and so system had X clock rate and so and so system had Y clock rate, which is faster, so Y system should be able to emulate X system. NO NO NO

take a look at existing computer cpu's

if we were to do an apples to apples comparison with a P4 3.0ghz to a Athlon XP 3000+ (both are 32bit cpu's) we would see that the XP 3000+ has alot lower clock rate than the P4, now does that mean it is slower? NO, it has a different architecture therefor allowing it to process data faster than the P4 3ghz.

clock cycles in this day and age mean NOTHING!! hence why all major chip manufacturers got away from the "ghz" naming convention..

sorry this was a rant.. but i just want people to be somewhat more educated before they start making retardo claims about a system having faster clock cycles so it in turn should be able to emulate another system with lower clock cycles.

there is ALOT more to it than mhz....

 

[funnystory]

idk i just heard that xbox fact somewhere.
USB iso loaders were always technically possible.Its just impossible emulating an xbox 360 on a regular xbox because of hardware.But since usb iso loader is software it is possible.

 

[EnigmaXtreme]

So i guess we cant emulate consoles from the last generation eh? Oh well, still i would love for WiiSX to actually run PSX discs, itll be like the colecovision back in the 80's XD

The Wii is in all likelihood not powerful enough to emulate a PS2 at a playable speed. The Wii will also probably never be able to emulate PSX games straight from disc since the DVD drive firmware can't read CDs, only DVDs (normal and the modified form used for Wii and GameCube discs).

It's silly to say the Wii is no more powerful than the Xbox because of things like:
1. You're comparing clock speeds across not only different processors, but across different architectures and fabrication processes. For example, a 1.8ghz Core 2 core is faster than a 3ghz Pentium 4, and they're both x86 family processors. PPCs also generally perform better than x86es like the Xbox's Celeron-ish processor clock for clock.
2. IOS runs on the ARM core, meaning that the only non-game code running on the main processor is the Nintendo libraries that developers use. The Xbox runs heftier Windows kernel-ish OS-like code at all times.
3. Nintendo works from an embedded systems-style approach whereas Microsoft works from a desktop computing-style approach, meaning that Nintendo work harder to squeeze more out of the hardware they've got (that comes at a cost - a lot is set in stone without an expensive hardware redesign.)
4. The Wii has dedicated hardware for certain features (e.g. hashing/encryption) that the Xbox has to do in software at a much slower speed.
5. The overall system architecture is targeted at games, whereas the Xbox has a more general purpose architecture, especially given that it's basically a proprietary PC.
6. The Wii's buses, components etc are often higher-spec/faster because manufacturing technology has improved over time. Especially with the RAM - the Xbox used the shittiest RAM Microsoft could buy, even ones that failed normal QC. The console would step down the RAM speed to maintain reliability.

The GameCube wasn't far behind the Xbox when it came down to it and the Wii is significantly faster than that. I'm not saying the Wii is a powerhouse but it's not last-gen either.

 

[PainToad]

Sure, and PS3 and 360, o and it can run Crysis.

Sigh.

 

[Commadore64]

CPU benchmarks
PS3 - 217.6 GFLOPS
PS2 - 6.2 GFLOPS
PS1 - ??? MFlops (cant find info)
PSP - 2.6 GFLOPS
Wii - 2.9 GFLOPS

In theory, if you decompiled a PS2 ISO into source, converted it into a Wii friendly format, and then recompiled it as a Wii ISO, some games might work sometimes, on some Wiis. Maybe.

Of course, decompiling a program is like turning gold into lead, then converting it to carbon, and finally recompiling it into a diamond.
1: Decompilers aren't perfect, period. Even for open source libraries.
2: We don't even know the native libraries used for PS2 games, and probably won't find out enough about them to even attempt this feat.
3: Conversion isn't kind. That's why ports take time, and are STILL worse than the original a lot of the time.
4: We don't have Wii compilers for anything that advanced anyway.

^Raw emulation of PS2 on Wii hardware is harder than this^
Feel like it should be done? Prove us all wrong and do it.

 

[googjew]

Meh. Don't you know about the PS4 emulator Waninkoko, Marcan, Nintendo, and Sony all worked together on coding for the wii. 1440p games look SO GOOD on that emulator, better than the PS4 itself.....Not to mention the blu-ray.

all points are plain wrong, this not a matter of having decompiler/compiler(which we already have) or libraries: this is a matter that porting anything WITHOUT the sourcecode is impossible. Also you can NOT retrieve the source code by decompiling the binary, contrary to what you seem to think

now, PS2 emulators exist but aren't even perfect on high-speed computers
and emulation is always related to mimic ALL the original hardware (CPU,SPU,GPU, Memory Managment, etc) behaviour using mostly software (i.e only one CPU): it's not only the speed of the original cpus but also the complexity of the architecture, the Wii is just not powerful enough for that

 

[Commadore64]

Yes Jacobeian is correct.
You cannot simply take custom code from 1 machine, decompile it, and recompile it for another machine.

There needs to be emulation in place

For example, say you wanted to run Wii games on Xbox 360 (just randomly picking console here guys). Even if one could decompile Wii, we need to convert TEV (graphics engine of the Wii) to DirectX (or its equivalent on the Xbox)
Lets say the Wii programmer did some undocumented call on the Wii to get some spectacular graphics. Something that was not documented in the Wii Software Development Kit. It works, it works great as a matter of fact on the Wii. But the Xbox would probably choke on it

me personly, im waiting for the X-Box 1440 emulator.... i have heard it runs well on a commadore 64 or a ZX Spectram

also the PS4 emulator has been confirmed to work on GB/GBC and the GBA.... with just little lag

XD

 

[MG4M3R]

LOL, already thinking about a PS2 emulator for Wii?

Frist let's make the PSX, N64 and Saturn emulators run properly, or at last the N64 one.


A Dreamcast emulator for Wii look's possibly, but PS2? lol

 

[Commadore64]

I dont think Dreamcast would be possible either - for same reasons

Remember the Wii needs to decompile Dreamcast code on the fly, convert to equivilent Wii code and simulate a Dreamcast environment without missing a step

Look at Wii64 performance
N64 100-200 MFLOPS and it performs at 50% speed on the Wii

Correction:
The emulated Dreamcast CPU needs to handle the machine language code being read into memory. And the graphics needs ot be handled correclty to be properly displayed on the Wii
It does not decompile and recompile - or interpile (I think that is the term, interpret and compile)...but it does not

Aren't N64 games from the Wii Shop channel emulated when they play on Wii?
