To be fair, PS2 was emulated by the PS3 perfectly which is much less powerful than PCs today. So it is more likely possible if you are the manufacturer of the console and you have access to things most people don't. Also, the Dolphin emulator for Wii/Gamecube is a piece of art. It makes Wii games look better than PS3 and 360 games do on fairly non demanding hardware. Come to think of it, Power PC architecture is used in nintendo Wii and that is being emulated fine...so this may not be impossible. |
The PS3 (60GB Launch)included the PS2 chipset (EE/GS) that's not emulation, the other option (80GB Bundle) excluded the EE but retained the GS and did the rest through emulation but the compatilbity wasn't as good. When they dropped all the PS2 parts they dropped backwards compatibility as well. So no, it never emulated the PS2 much less perfectly as you described.
The GC/Wii chipset is super simple and stripped down (much like the 360 chipset), but it's single core and clocked very low. So it's prety easy to emulate as even the GPU is ancient and stripped down. The hardest part was the custom memory setup, as GC/Wii both use 1T-SRAM (really fast) but not enough of it to make it an issue. And really RAM is hardly ever the problem, it's the processors and the more chips/processors you have to emulate the harder it is to do at a decent speed. One of the reasons why something like the original PSX is a piece of cake compared to something like the Sega Saturn or Atari Jaguar which both used multiple processors for various system tasks.

It also seemed pretty hard for the Xbox 360 to emulate the Xbox, especially given the fact that the CPU was completely different (jumping from x86 to Power architecture) and the GPU was of another brand as well... But nevertheless, they did it. |
Actually no, the Xbox hardware is ancient and super simple as well and is really just a PC if ever there was a console that could be described as such. Even then they have to pay nVidia for using the "schematics" if you will for the original XGPU as it was the only custom chip in there, but it really was just a half-way point between a NV20 and NV25 with a feature or two from the NV30 if I'm remembering this right. The CPU itsels was a half-way point between a Celeron and a Pentium III but closer to the P3, either way very simple and clocked pretty low so nothing too taxing. And the Emulation is lacking, as there are still tons of games not covered and those that are can have graphical glitches.
@vlad321
You said that your GPU is stronger than the entire 360 like that meant something when it comes to emulation, and then you went on to say that machines that are several years old could easily emulate the 360 no problem (When many of them can't even run native PC games as well as a 360, you did say hardware you NEVER implied a capable gaming rig). It sounds like you're the one that doesn't know shit and is trying to sound like you do. Tell me, why should I waste my time on you? If somebody has to explain to you the complexity of emulating a Tri-Core CPU clocked @3.2 Ghz (in-order but still multicore with a total of 6 threads and reasonably fast) and a custom GPU with embedded eDRAM on modern systems, then you're really not in a position to go around declaring anything. The worst part is that you're so sure about what you're saying when you barely have a clue.
