- SH4 emulation now allows NetBSD/dreamcast to reach
userland.
- A framework to let emulated clocks run at same
speed as the host clock has been added.
- The built-in debugger's expression syntax has been changed.
- Better MIPS emulation for some combination of emulated
processor and guest operating system.
- Bug fixes.
- NetWinder emulation mode works well enough to let NetBSD/netwinder
run from a disk image.
- Algorithmics P5064 emulation works well enough to let NetBSD/algor
run from a disk image.
- PCI configuration register writes are now handled, which allows
NetBSD/Malta (evbmips) 3.0.1 and NetBSD/cobalt 3.0.1 to run
from PCI IDE harddisk images.
- Some performance increases for translation table updates.
Major upstream changes from the previous ported version
include:
- speedups for MIPS emulation,
- an improved dyntrans backend,
- tweaks to ARM, PPC, AVR, SPARC and MIPS emulation,
- support for remote debugging using GDB,
- a new statistics gathering option "-s",
- most configuration options are no longer supported,
- bug fixes.
Port changes:
- the port no longer depends on GCC >= 3.2 on FreeBSD 4.X.
- OPTION "X" has been renamed as "X11" for consistency.
- i80321 (XScale) mode can run NetBSD/evbarm,
- performance speedups for framebuffer output
- most CPU types are enabled by default.
- Remove obsolete USE_REINPLACE directive.
- Add a local MASTER site.
- Take over port maintainership.

for a long changelog between these releases. Summary: vastly improved arm,
mips and ppc support. Lots of new CPUs and a better dynamic code generator
for the instructions emulated. Vastly improved hardware device emulation.
Can boot many free and obscure guest operating systems.
GXemul is a free instruction-level machine emulator, emulating not only the
CPU, but also other hardware components, making it possible to use the emulator
to run unmodified operating systems such as NetBSD, OpenBSD, or Linux.
A few different machine types are emulated. The following machine types are
emulated well enough to run at least one "guest OS":
* DECstation 5000/200 ("3max"): serial controller (including keyboard and
mouse), ethernet, SCSI, and graphical framebuffers.
* Acer Pica-61 (an ARC machine): serial controller, "VGA" text console, and
SCSI.
* NEC MobilePro 770, 780, 800, and 880 (HPCmips machines): framebuffer,
keyboard, and a PCMCIA IDE controller.
* Cobalt: serial controller and PCI IDE.
