E-UAE 0.8.29-WIP4
=================
E-UAE is an Amiga emulator, a program that allows you to run software
designed for Amiga computers on other platforms, such as Linux or Mac
OS. It is based on UAE, the original Ubiquitous Amiga Emulator, and
WinUAE, the Windows version of UAE. While it owes a huge debt to these
two great projects, E-UAE diverges from both, aiming to improve
performance and features on a variety of host platforms.
The name E-UAE stemmed from the fact that this project needed a name,
and, since it was an 'experimental' version of UAE, everybody was
calling it 'Experimental' UAE. While I have long since accepted that
moniker, I still don't intend the 'E' to mean anything it particular.
Although the project is currently 'experimental' - that is, it is a
long way from being anything close to finished - it should still be
robust enough to use.
E-UAE currently builds and runs - with varying degrees of supported
features - on Unix and Unix-like platforms (including Linux, Solaris
and Mac OS X), BeOS, AmigaOS and clones (including AmigaOS 3.x,
AmigaOS 4.0, MorphOS and AROS), and Windows (with Cygwin or MinGW32).
E-UAE is open-source software and is made available under the terms of
the GPL. See the COPYING file included with the E-UAE archive for
details.
E-UAE is based on the work of dozens of contributors including Bernd
Schmidt (the original author and maintainer of UAE), Bernie Meyer (the
author of the x86 JIT compiler), Toni Wilen (the current maintainer of
WinUAE), and many more.
Note that to make full use of E-UAE you will need access to an image
of some version of the Amiga Kickstart ROM (although E-UAE does include
a ROM emulation which may work with some old games). The Amiga
Kickstart ROMs are copyrighted material and may not be freely
distributed (so don't ask me for a copy). If you don't have an Amiga
from which you can legally make a ROM image, a selection of ROM images
are available for purchase online from Cloanto (publishers of the
Amiga Forever distribution). See http://www.amigaforever.com/
What's new since 0.8.29-WIP3
============================
A huge amount of work has gone into E-UAE since the last public
release. Not of all of this work will be readily apparent to users
since it took place under the surface. However, some user-visible
changes include:
* Emulation core from WinUAE 1.3.x merged.
* Much more stable on SMP hosts.
* Builds on Solaris x86 (with GCC).
* Integrated mouse-hack feature merged from WinUAE (this synchronizes
the Amiga mouse pointer with the host pointer when E-UAE is running
in a window on your desktop) merged from WinUAE. The old AmigaOS
mousehack tool is no longer required.
* New, easier-to-use Linux SCSI back-end (Jochen Becher).
* Experimental GL renderer in SDL display back-end (originally from
Jochen Becher but mostly re-written). On most platforms this is yet
to offer much over the existing 2D renderer, but on Mac OS X it
offers significantly better performance. Enabled with
'sdl.use_gl=true'.
* Support for the 'uae-configuration' tool merged from WinUAE. This is
an AmigaOS shell command which allows UAE settings to be queried and
modified from within the emulation environment.
* Better, smoother performance when cpu_speed=real (A500 speed). E-UAE
adapts better to changing system latencies.
* 'Sinc' audio interpolation added (Antti Lankila).
* Minor performance improvements in interpretive CPU emulator and JIT
engine.
* Mac OS X icon added (from Daniel Pimley).
* Lots of bugs fixes, including:
- Broken 'delayed' interrupt handling when JIT was disabled.
- Inconsistent refreshing of P96 screens.
- Filesystems being mounted twice.
- Hardfiles broken following a reset.
- Broken detection of XKB path in X11 driver (fix from Peter Volkov).
Still to do
===========
The following features of UAE and/or WinUAE are not yet supported yet
in E-UAE. These include:
* Serial and parallel port emulation.
* AHI soundcard emulation.
* Catweasel support.
* Graphics filters, scaling, etc.
* Floppy drive sounds.
Known problems
==============
Some significant misfeatures that I know about and am/will be working
to fix (eventually):
* Only platforms supporting the GTK+ toolkit have a useable
configuration GUI (and the GTK+ GUI is still incomplete). However,
Mac OS X users may like to try Daniel Pimley's graphical front-end,
Hi Toro. See http://www.pimley.net/projects/.
* JIT direct memory access only works on Linux/x86 and, by default,
you may only emulate up to 32MB of direct ZIII RAM; select more than
that and the JIT will fall back on indirect memory access and hence
will be slower. This is due to a system limit on the size of a POSIX
shared memory segment. You can overcome this limit my modifying the
value of the procfs setting, /proc/sys/kernel/shmmax.
* Virtual filesystem doesn't support platforms which use UTF-8 for
filenames (e.g., OS X, Linux with a UTF-8 locale, etc.). Filenames
with characters outside of the core ASCII range will be mangled.
* OpenGL renderer is experimental, unfinished and has no error
recovery.
* Tear-free graphical output (with the gfx_vsync=true option) doesn't
work on most platforms yet (the exceptions being Mac OS X with the
SDL/GL renderer and AmigaOS4.0 with SDL).
* The Mac OS X version is currently for PowerPC hardware only (I don't
have an Intel Mac). Users with Macintel hardware may wish to try
Jens Weichert's Intel builds. See http://e-uae.de.vu/.
* The build scripts are a horrible, unmaintainable mess.
* Full documentation is lacking.
Using E-UAE

Documentation is a work-in-progress. See the docs directory.
