The GXemul source code is released as Free Software.
It should be possible to compile it on most Unix-like
systems with few or no modifications.
The latest stable release is available for download here:
(The README file, RELEASE notes, Documentation, etc, for a specific release are
always included in the corresponding .tar.gz archive. For convenience, the
documentation etc. of the latest stable release is also available on-line.)
An excerpt from the release notes:

The main change between release 0.4.7.2 and 0.6.0 is:
- Since late 2007, a complete rewrite of the emulator's base framework
has been going on. GXemul 0.6.0 is a very early release
of the new framework. So far, only the
testm88k machine mode
has been rewritten to use the new framework, all other machine modes
run in legacy mode using the old framework (which is still included).
In other words: For most emulation modes, 0.6.0 will be
exactly like 0.4.7.2.
The new testm88k mode is much less complete than the old
testm88k; the reason for concentrating on this mode is to be able
to make an initial release of the new framework within a reasonable
time frame.
Compared to the other emulation modes, there are lots of things left
to do before the new framework can be considered working:
There are no lookup tables for fast loads/stores, no fast pc-to-pointer
lookups, no interrupt/trap/exception handling, no timers,
no breakpoint support, no general expression parsing, no I/O
(serial controllers nor graphical output handlers), no disk or
ethernet support, no MMU/virtual memory translation, and snapshotting
(for reverse debugging) isn't implemented yet. Still, it is probably
better to make many smaller releases (0.6.x) than to wait until
everything is in place.
There is also a (bogus) testmips machine which will be
implemented using the new framework. To use the old testmips
machine, please use the name oldtestmips instead.
In addition to the new framework, a couple of other changes are worth
mentioning:
- Many unused, rarely used, and bogus emulation modes and features
were removed, to reduce the maintenance burden.
- Some operating systems listed on the
guest OS page have had new releases;
the documentation has been updated to reflect this.
- New source code (but not the legacy part) is
documented using Doxygen comments,
and there is a unit testing framework in place.
- There is now finally an install Makefile target, and
the -j make option can be used to parallelize builds.
Please read the HISTORY file for more details.
