CherryOS is a G4 Emulator giving you the option to use OSX on your PC.

In reply to Comment 1 (hooligan/dcs):
If it's not fake then it will be wery slow. I think there was news about ppc emulator year ago or something like that, but it was slow like hell. And I think it emulated 601, 603 or something like that, G4 is much more complex.

I aggree, I would be surprised if this is not a fake.

Is it better than Amithlon?

erm.... have you never used PearPC? http://pearpc.sf.net

OS9 is very fast on my 1GB RAM Athlon64 3200+ running on 64bit linux, and OSX is usuable, but not very responsive.

Sheepshaver emulates PPC MacOS upto OS9 too on BeOS and Linux.

People just have a tendancy to believe just about anything is impossible unless they actually see it. It's been that way all through out history. Inventors are always mocked and laughed at until their inventions are finally seen by people and proven to work.

In the Amiga community it is no different. There are hundreds of things people have said are Impossible on the Amiga, but weren't. From people saying UAE would never usable to Parallel port ZIP drives not working on the Amiga. As we all know, UAE is now faster than any 68k Amiga could EVER dream to be. Things like the Parallel port ZIP drives were made to work not too long after they came out.

I hardly think that emulating a PPC chip at acceptable speeds will be "impossible".

"I'd expect a fake as well. In the Wired article they claim 80% speed..."

Apparently emulating the PPC isn't as hard as first thought; It's just no one could be bothered up until now, I still doubt there's anything that Mac OS can offer that a native os couldn't. I suspect that the current "cool" factor Mac OSX has is driving the move for useful PPC emulators opposed to development PPC emulators.

Seems like a waste of time to me ...

>80% speed

Questionable how noticable that 20% loss would be where serious number crunching is not required.

Does the "VNC" tray icon, as seen in the first screeshot from their web page, mean something?

80% ?? Well even if that would be possible, I really don't believe that includes AltiVec.

G4'Altivec is about 7 time faster than Intel CPU (using vectorial unit as well)
and 4 times faster than AMD (vec too) at the same frequency.

So don't dream to much. Also AltiVec register are 128bit width and SSE2 only 64...

In reply to Comment 9 (corpse):
I've seen Amiga emulators on 2ghz systems that struggled at times to fully emulate 040 amiga speed. To emulate a ppc system that is several orders of magnitude more sophisticated? I'm not saying it can't be done, just that I'd have to see it to believe it.

In reply to Comment 13 (Anonymous):
Actually, 3DNow(recycles X87 registers) is 64bit wide, while SSE2 (XMM registers) 128bit wide. Software such as RC5 uses vector instruction such as vector rotate. Such instructions doesn’t exist in X86 land i.e. it has to use scalar version. One of the reasons why AMD preform better than PIV in RC5 is due to 3 integer scalar pipelines.

As indicated via SSE -> SSE2 -> SSE3 evolution, X86/X64’s SIMDs are currently under construction i.e. adding vector instructions. Generally, X86 world targets desktop world usage.

Running PPC Linux on PearPC 0.4pre is fast enough but MacOS X is usable (needs HW accelerated GPU for MacOS X graphical effects).

Looks like it's just a ripoff of pearpc:
