* Included Linux image works fine on NetBSD/amd64 6.99.23
Changelog:
New features
Addition of ports to Amiga OS 3 and OS 4.
Sound emulation.
Support for RAM sizes other than 4MB (512KB, 1MB, 2MB,
4MB, 8MB, 12MB & 16MB now supported).
ARM250 & ARM3 CPU emulation.
ArcEm clock set from host's clock, partial RTC support.
Extension ROM emulation, allowing support for the
following new features when emulation RISC OS:
HostFS - A RISC OS filesystem to allow use of a
directory on the Host Filing system as a virtual
hard drive.
Mouse scroll wheel support.
Extra video modes, up to 1024x768 in 16 colours and
800x600 in 256 colours.
Bug fixes/Improvements
Many performance tweaks and optimisations, resulting in
a 5-6 times performance gain on ARM hosts. A 600MHz
XScale can now achieve a level of performance roughly
equivalent to an 8MHz ARM2. Similar performance gains
can be seen on other low-power hosts.
Video emulation rewritten to provide accurate redraw
and VSync timing, down to the scanline level.
Video emulation now supports upscaling and aspect ratio
correction for rectangular pixel modes.
All hardware clocks/timers (IOC timers, video DMA, audio
DMA, etc.) now run in real time, ensuring one second
takes one second no matter how fast the host machine
is.
Source code tidied a bit to remove redundant code,
including support for emulation of 32bit processor modes
(there are other, much better emulators for that!).
Source code converted to use C99 number types to aid
portability.
Instruction prefetch now correctly emulated - ensures
correct operation with self-modifying code and some
forms of copy protection.
RISC OS version now 32bit compatible, and ARMv7-safe.
Also much more useable with modern machines/LCD monitors
as it no longer requires the host to be able to support
Archimedes screen modes.
Windows version updated to build under Visual Studio
2010 (including Express edition).
Unix/X11 version now supports X servers that don't
support XWarpPointer.
libXext/buildlink3.mk, now that it is included there.
Leave the places where its API version is set or variables from it
are used directly (about 3 packages).
Several changes are involved since they are all interrelated. These
changes affect about 1000 files.
The first major change is rewriting bsd.builtin.mk as well as all of
the builtin.mk files to follow the new example in bsd.builtin.mk.
The loop to include all of the builtin.mk files needed by the package
is moved from bsd.builtin.mk and into bsd.buildlink3.mk. bsd.builtin.mk
is now included by each of the individual builtin.mk files and provides
some common logic for all of the builtin.mk files. Currently, this
includes the computation for whether the native or pkgsrc version of
the package is preferred. This causes USE_BUILTIN.* to be correctly
set when one builtin.mk file includes another.
The second major change is teach the builtin.mk files to consider
files under ${LOCALBASE} to be from pkgsrc-controlled packages. Most
of the builtin.mk files test for the presence of built-in software by
checking for the existence of certain files, e.g. <pthread.h>, and we
now assume that if that file is under ${LOCALBASE}, then it must be
from pkgsrc. This modification is a nod toward LOCALBASE=/usr. The
exceptions to this new check are the X11 distribution packages, which
are handled specially as noted below.
The third major change is providing builtin.mk and version.mk files
for each of the X11 distribution packages in pkgsrc. The builtin.mk
file can detect whether the native X11 distribution is the same as
the one provided by pkgsrc, and the version.mk file computes the
version of the X11 distribution package, whether it's built-in or not.
The fourth major change is that the buildlink3.mk files for X11 packages
that install parts which are part of X11 distribution packages, e.g.
Xpm, Xcursor, etc., now use imake to query the X11 distribution for
whether the software is already provided by the X11 distribution.
This is more accurate than grepping for a symbol name in the imake
config files. Using imake required sprinkling various builtin-imake.mk
helper files into pkgsrc directories. These files are used as input
to imake since imake can't use stdin for that purpose.
The fifth major change is in how packages note that they use X11.
Instead of setting USE_X11, package Makefiles should now include
x11.buildlink3.mk instead. This causes the X11 package buildlink3
and builtin logic to be executed at the correct place for buildlink3.mk
and builtin.mk files that previously set USE_X11, and fixes packages
that relied on buildlink3.mk files to implicitly note that X11 is
needed. Package buildlink3.mk should also include x11.buildlink3.mk
when linking against the package libraries requires also linking
against the X11 libraries. Where it was obvious, redundant inclusions
of x11.buildlink3.mk have been removed.
Changes are
- New manual and new SourceForge page. Other documentation deprecated.
- Added project files for MS VC++, and fix warnings provoked by it.
- Further split of windowing/non-windowing functionality to aid division
of architecture-independent files.
- Windows version made independent from Cygwin.
- Windows support imported from eQRD version. Features brought inline with
other versions, including icon change, and same format for choices file.
- Entirety of build warnings fixed under GCC, including those that appeared
from turning on harsh warning flags.
- General tidying.
- Makefile rearranged so that default Unix builds are more sensible.
- Support for running RISC OS, by Alex Macfarlane Smith and Peter Naulls
- Split of the windowing aspects of the code, to allow independent development.
- Some small speed ups.
- Source code tidying and warning fixes.
