<h1 id="changelog">Change Log</h1>
<dl>
<dt><strong>ArcEm 1.50.1</strong> – 18th December 2015</dt>
<dd>
<ul>
<li>This is just a maintenance release for the RISC OS version of ArcEm. There are only two notable changes compared to 1.50:</li>
<ul><li>The released binary has been compiled with GCC 4.7.4, eliminating a null pointer deference bug that was present with the previous version of GCC/UnixLib</li>
<li>Support has been added for the new screen modes introduced with RISC OS 5.21 (e.g. 64k colour modes and red/blue swapped modes), improving compatibility with new machines</li></ul></li>
</ul>
</dd>
<dt><strong>ArcEm 1.50</strong> – 16th December 2012</dt>
<dd>
<ul>
<li>New features
<ul>
<li>Addition of ports to Amiga OS 3 and OS 4.</li>
<li>Sound emulation.</li>
<li>Support for RAM sizes other than 4MB (512KB, 1MB, 2MB, 4MB, 8MB, 12MB & 16MB now supported).</li>
<li>ARM250 & ARM3 CPU emulation.</li>
<li>ArcEm clock set from host's clock, partial RTC support.</li>
<li>Extension ROM emulation, allowing support for the following new features when emulation RISC OS:
<ul>
<li>HostFS - A RISC OS filesystem to allow use of a directory on the Host Filing system as a virtual hard drive.</li>
<li>Mouse scroll wheel support.</li>
<li>Extra video modes, up to 1024x768 in 16 colours and 800x600 in 256 colours.</li>
</ul></li>
</ul></li>
<li>Bug fixes/Improvements
<ul>
<li>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.</li>
<li>Video emulation rewritten to provide accurate redraw and VSync timing, down to the scanline level.</li>
<li>Video emulation now supports upscaling and aspect ratio correction for rectangular pixel modes.</li>
<li>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.</li>
<li>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!).</li>
<li>Source code converted to use C99 number types to aid portability.</li>
<li>Instruction prefetch now correctly emulated - ensures correct operation with self-modifying code and some forms of copy protection.</li>
<li>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.</li>
<li>Windows version updated to build under Visual Studio 2010 (including Express edition).</li>
<li>Unix/X11 version now supports X servers that don't support XWarpPointer.</li>
</ul></li>
</ul></li>
</dd>
<dt><strong>ArcEm 1.00</strong> – 6th May 2002</dt>
<dd>
<ul>
<li>New manual and new SourceForge page. Other documentation deprecated.</li>
<li>Added project files for MS VC++, and fix warnings provoked by it.</li>
<li>Further split of windowing/non-windowing functionality to aid division of architecture-independent files.</li>
<li>Windows version made independent from Cygwin.</li>
<li>Windows support imported from eQRD version. Features brought inline with other versions, including icon change, and same format for choices file.</li>
<li>Entirety of build warnings fixed under GCC, including those that appeared from turning on harsh warning flags.</li>
<li>General tidying.</li>
<li>Makefile rearranged so that default Unix builds are more sensible.</li>
</ul>
</dd>
<dt><strong>ArcEm 0.60</strong> – 30th September 2001</dt>
<dd>
<ul>
<li>Support for running RISC OS, by Alex Macfarlane Smith and Peter Naulls
<li>Split of the windowing code, to allow independent development.
<li>Some small speed ups.
<li>Source code tidying and warning fixes.
</ul>
