Changes:
Changes in 2.0 (December 21, 2002):

Since the change log is hundreds of lines long, here is a very brief summary.
- 2x emulation speedup!!!
- added plugin devices and guis. Now you can compile with many more
options, and choose between them at runtime.
- added emulation of AMD x86-64, MMX, SSE, SSE2 instructions
- add wxWindows port (a graphical configuration interface and display lib)
and SVGAlib port (full screen display for Linux without X11)
- improvements in many I/O devices: for example up to 8 hard disks/cdroms,
TUN/TAP network interface, 360k floppies,
- improved MacOSX/Carbon interface and updated MacOS9 port
- GDB remote stub, allows symbolic debugging with Bochs simulation.
- support for up to 32gig hard disk images

Emulation of x86-64? There aren't even x86-64 chips!!

Yes, it’s my fault.

No, definitely not. It specifically says AMD x86-64. Itanium isn't even compatible with x86 instruction sets, which is fucking stupid, and this fact will kill Intel.

Yes, it’s my fault.

So ?
There existed GBA emulators before the thing was released.

Based on x86-64 Architecture Tech Docs published by AMD here :
www.amd.com/us-en/Processors/ProductInf ... dir=CPX801

I believed Bochs 2.0 programmers just followed these docs.
Therefore emulation of x86-64 instructions looks possible.

How exactly do you emulate a 64-bit processor on a 32-bit processor? Hmm...

Yes, it’s my fault.

Now that's a damn good question, how about very very slow ?

64-bit processors are already being emulated on 32-bit processors. N64 emulators are living proof of that. 😉

as for how... i'm sure the sources to PJ64 or 1964 reveal varrious ways 😜

Good point, I suppose.

Good thing most n64 hardly use any 64bit code 😀
But emulating 64bit processors on a 32bit system is quite nasty yes , especially multiplication and division instructions. Wonder what kind of speed you'll get out of bochs then.
