[IGN] Report: PS4 Dev Kits Surface - Page 28  

post #271 of 468
Sweet this is exactly what I want from a console; an affordable way of playing the japanese fighters/rpgs that don't come out for pc. This probably also means that people who are expecting new consoles to jump start improved pc graphics will be disappointed though

Microsoft emulated the Xbox just fine..The original Xbox was far stronger than PS2.

Because the Xbox and Xbox 360 use the same line up of CPU's.
PS2 and PS3 use different chips.

Xbox used a Penitum 3 and 360 uses a PowerPC IBM chip so they couldn't be more different if they tried.

Uh what? The Xbox uses a Pentium III while the Xbox 360 uses 3 IBM PowerPC cores derived from the Cell Broadband Engine's PPU. The Xbox uses an x86 architecture while the 360 uses PowerPC which is a RISC architecture. Backwards compatibility is achieved through emulation since the 360 is powerful enough for that.

PS2 emulation should be possible on the Cell and RSX though developing the emulator can be quite difficult. Architecture-wise the SPUs can be used for processing instructions for the 2 vector processors with the PPU handling CPU instructions. I don't know how the Graphics Synthesizer would be emulated though.

It can't...... The graphics synthesiser has more memory bandwidth and real world fillrate then RSX and even 360's Xenos chip.

I guess I am forgetful at times. Here's the thing, there is a good PS2 emulator developed for x86 CPU's. Now how do you emulate a console that used the most difficult CPU architecture on to another machine that uses a unique CPU architecture.

It's easy if you have the CPU micro code to work from, Sony do have that code so it should be an easy job.

At this time, it's more useless to do so. There are some on PSN. But with the new consoles within the next 2 years and people still have their PS2's anyway... they might as well just integrate PS1 and 2 emulation into the PS4. Oh and if the PS3 was to be backwards compatible on the PS4, an emulator would show up on PC within a month of the PS4's release.
