<p> What has changed in Mini vMac 3.0.4, compared to Mini vMac 2.8.2.
|
|
This only lists changes that affect behavior, and so doesn't
|
|
include cleanups of the source code. </p>
|
|
|
|
<p> : </p>
|
|
|
|
<p>
|
|
default compile:
|
|

|
|
|

<p> : </p>
|
|
|
|
<p> <a name="feature"> <b> New features in default compile </b> </a> </p>
|
|
|
|
<p> * Mini vMac now provides certain new capabilities
|
|
for software running within the emulated machine, including
|
|
getting and setting the host clipboard, using raw files
|
|
on the host computer (disabling any interpretation as
|
|
a disk image), creating new files (disk images or raw files),
|
|
deleting files mounted with write permission, and getting
|
|
the names of files. </p>
|
|
|
|
<p> Software using these capabilities include: </p>
|
|
|
|
<blockquote>
|
|
<p>
|
|
<a href="../extras/clipout/index.html">ClipOut</a> - exports the clipboard
|
|
<br>
|
|
<a href="../extras/clipin/index.html">ClipIn</a> - imports the clipboard
|
|
<br>
|
|
<a href="../extras/exportfl/index.html">ExportFl</a> - exports files from Mini vMac
|
|
<br>
|
|
<a href="../extras/importfl/index.html">ImportFl</a> - imports files into Mini vMac
|
|
</p>
|
|
</blockquote>
|
|
|
|
<p> The new capabilities were carefully designed to avoid allowing
|
|
software running in the virtual machine to do any serious
|
|
harm. But if this is a concern, all the new capabilities can
|
|
be disabled with the compile time option
|
|
<a href="../options.html#option_min_extn">-min-extn</a>. </p>
|
|
|
|
<p> <a name="modified"> <b> Changed behavior in default compile </b> </a> </p>
|
|
|
|
<p> * By default, the Macintosh versions of
|
|
Mini vMac will now not claim ownership to disk image and
|
|
ROM image files. So double clicking on disk images
|
|
will not launch Mini vMac. This is because when
|
|
you have lots of copies of Mini vMac around,
|
|
all of which claim ownership of disk images,
|
|
it is unpredictable what happens when you
|
|
double click on one, making the feature useless.
|
|
Instead there is a compile time option,
|
|
<a href="../options.html#option_im">-im 1</a>,
|
|
to make Mini vMac claim ownership as has
|
|
been done previously. You can then make sure
|
|
to have only one copy of Mini vMac compiled
|
|
this way on your computer. </p>
|
|
|
|
<p> * The stopped mode toggle is now Control-S-D
|
|
instead of Control-S-S. Before I had wanted to make
|
|
it quick to type, but now I think it is more important
|
|
to prevent hitting it accidentally. </p>
|
|
|
|
<p> * When switching back to the Mini vMac application,
|
|
previous versions would always ignore keys
|
|
that were already held down. There is now
|
|
a special case such that immediately after
|
|
a drag and drop on to the Mini vMac window, it will not ignore
|
|
keys already held down. This makes it easier
|
|
to rebuild the desktop of disk images by
|
|
holding down command and option. However,
|
|
the keys that map to command and option can
|
|
have special meanings in other operating systems.
|
|
(For example, in OS X, clicking on the window
|
|
of another application with command and option
|
|
down will hide all other applications.) So
|
|
it usually works better to press command-option
|
|
right before dropping, instead of before dragging.
|
|
(Thanks to a complaint by
|
|
<a href="http://woodwynlane.com/">David Sibley</a>
|
|
for this feature.) </p>
|
|
|
|
<p> * An obscure change is that when entering the
|
|
control mode, or the open dialog, or switching
|
|
to another application, all the emulated
|
|
keys (except for caps lock) are released
|
|
immediately, instead of waiting until
|
|
normal emulation resumes. </p>
|
|
|
|
<p> * An even more
|
|
obscure change is that in the control mode,
|
|
changes to the caps lock key take effect
|
|
immediately, instead of waiting until leaving
|
|
the control mode. </p>
|
|
|
|
<p> * The variation name displayed
|
|
in the about message, and used for program binary archive names,
|
|
no longer includes the development environment
|
|
used to compile it or the debug status, but only
|
|
has the program name abbreviation, the
|
|
version number, and the target. Such as
|
|
minivmac-3.0.4-imch, for the Intel Macintosh
|
|
version of Mini vMac 3.0.4. </p>
|
|
|
|
<p> <a name="bugs"> <b> Bug fixes in default compile </b> </a> </p>
|
|
|
|
<p> * Mini vMac for PowerPC Macintosh OS X was not compatible with OS X 10.5,
|
|
due to a bug in the PowerPC assembly code used for 680x0 emulation. (It's
|
|
surprising that it worked previously.) </p>
|
|
|
|
<p> * A call to XFlush was missing in the X version (such as
|
|
the Linux port), and the most noticeable effect was
|
|
the lack of drawing when Mini vMac was in the
|
|
background with the run in background option on. </p>
|
|
|
|
<p> * In OS X, and also earlier Mac OS,
|
|
dragging and dropping onto the open file dialog
|
|
would also immediately try to mount that file in
|
|
Mini vMac. </p>
|
|
|
|
<p> * The Windows and X versions now support the
|
|
PageUp, PageDown, Home, End, Help/Ins, and
|
|
ForwardDelete keys. </p>
|
|
|
|
<p> * The mouse position
|
|
could shift slightly when leaving full
|
|
screen mode (or entering the open dialog
|
|
in full screen mode). </p>
|
|
|
|
<p> * In the Macintosh versions {mouse down,
|
|
control-o, mouse up, type escape key} would
|
|
leave the emulated mouse stuck down. </p>
|
|
|
|
<p> * In Ubuntu Linux, drag and drop on to the
|
|
Mini vMac window would not activate Mini vMac.
|
|
This is fixed by sending a _NET_ACTIVE_WINDOW message in
|
|
the X version when it is claimed to be supported.
|
|
So forcing the Mini vMac window to activate
|
|
will probably now work with more Linux distributions (and other X),
|
|
but there are undoubtedly still distributions
|
|
where it won't work. </p>
|
|
|
|
<p> * If buggy or malicious low level software running in the
|
|
emulated computer wrote past the end of a disk image,
|
|
it would make the disk image larger. Mini vMac will
|
|
now do explicit range checking for both read and write,
|
|
and not just pass it directly to the platform specific calls. </p>
|
|
|
|
<p> * The Macintosh OS X version wouldn't work with a
|
|
disk image on a CD. </p>
|
|
|
|
<p> * In the Macintosh OS X version, magnify
|
|
toggle wasn't smooth. Now just create
|
|
a new window, rather than moving then
|
|
resizing the existing window. </p>
|
|
|
|
<p> <a name="build"> <b> Build System </b> </a> </p>
|
|
|
|
<p> * The build system is now a Macintosh program that runs in
|
|
Mini vMac (it would also work on a real 680x0 Macintosh).
|
|
After you specify the options, the program generates an
|
|
archive containing all the files needed to compile Mini vMac
|
|
with those options in the selected development
|
|
environment. If the build system is running in Mini vMac
|
|
3.0.0 (or later), then this archive will then automatically
|
|
be exported to the real computer, where you can extract the
|
|
files and compile the program. The
|
|
<a href="../build.html">Building Mini vMac</a>
|
|
page gives more details. </p>

|
|
<p> * A Dutch translation from
|
|
<a href="http://luc.xalasys.com/mac/minivmac.html">Luc Pauwels</a>
|
|
(option “<a href="../options.html#Language">-lang dut</a>”),
|
|
and a Spanish translation by
|
|
“<a href="http://www.geocities.com/chir_geo/">Chir</a>”
|
|
(option “<a href="../options.html#Language">-lang spa</a>”). </p>
|
|
|
|
<p> * In the Windows version, the
|
|
<a href="../options.html#option_im">-im 1</a>
|
|
option will cause
|
|
Mini vMac to install itself on launch
|
|
into the Microsoft Windows registry, so that
|
|
double clicking on a disk image file with
|
|
the extension '.dsk' will open it with Mini
|
|
vMac, and so that such disk image files and
|
|
also '.rom' files will be displayed with
|
|
custom icons. This make the separate
|
|
utility <a href="../extras/mnvmreg/index.html">MnvMreg</a> obsolete. </p>
|
|
|
|
<p> * An option to swap the emulated Control and Command keys
|
|
(“<a href="../options.html#option_ccs">-ccs</a>”). </p>
|
|
|
|
<p> * An experimental option for making some keys more convenient
|
|
to use.
|
|
(“<a href="../options.html#option_akm">-akm</a>”). </p>
|
|
|
|
<p> * An initial speed setting
|
|
(“<a href="../options.html#WantInit">-speed</a>”). </p>
|
|
|
|
<p> * An initial Run in Background setting
|
|
(“<a href="../options.html#WantInit">-bg</a>”). </p>
|
|
|
|
<p> * A new alternate implementation of the 680x0 processor
|
|
(option “<a href="../options.html#option_alt_cpu">-alt-cpu</a>”).
|
|
It is a bit faster, cleaner, and makes it possible to be more accurate
|
|
about illegal instructions without speed penalty. However, this code is too
|
|
new for me to trust it yet, so it is not used by default. </p>
|
|
|
|
<p> <a name="compile_modified"> <b> Changed behavior not in default compile </b> </a> </p>
|
|
|
|
<p> * There are a number of refinements to playing sound using ALSA in
|
|
the Linux version, which is enabled with
|
|
“<a href="../options.html#option_s">-sound 1</a>”.
|
|
It may work more smoothly now. </p>
