This is a fork of UAE, the Ubiquitous Amiga Emulator, with an emulation core
based on WinUAE. It attempts to bring many of the great features of WinUAE
to non-Windows platforms. This version now finally has a name, E-UAE, since
that's what everybody was calling it anyway. The 'E' can stand for anything
you fancy. Experimental, extreme, exciting, egalitarian, eggplant, . . .
Currently it will build and run (with a varying degree of supported
features) on Linux and other Unices, Mac OS X, BeOS, AmigaOS itself
(either for 68k machines or PPC machines with OS4.0) and the AmigaOS clones
AROS and MorphOS. OS X requires either LibSDL or an X server for graphics
output, but native graphics are supported on AmigaOS and BeOS, although, at
the moment, SDL is also preferred on BeOS since the native driver is
incomplete.
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.
To make full use of E-UAE you will need access to an image of some version
of the Amiga Kickstart ROM (although 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

What's new since 0.8.27
=======================
General
-------
* Many core emulation changes and fixes merged from WinUAE 1.0.
* Optimized interpretive 68k emulation with speed improvements of up to 30%.
* Fixes for building with GCC 4.0.
* Fixes for building on 64-bit hosts such as the AMD64.
* Option not to use the CPU's time-stamp counter for synchronization on x86,
AMD64 and PPC machines (generally you will want to).
* Fixed virtual filesystem bug that was causing IBrowse to crash.
* Improved 'new' bsdsocket emulation (and it now works on OS X and on
AMD64/Linux too).
* Better screenmode support in SDL graphics driver.
* X11 driver supports raw key-mapping for xfree86 keycodes.
* Documentation updates (thanks to Henrik Farre for documenting the
command-line options).
Linux
-----
* Faster start-up on x86 and AMD64 systems and PPC systems with Open
Firmware (it's no longer necessary to perform TSC/TBC calibration at
start-up).
* CPU frequency scaling supported on x86/AMD64 systems.
OS X
----
* Faster start-up (it's no longer necessary to perform timing calibration at
start-up).
* Improved Cocoa menus and dialogs (thanks to Steve Saunders).
AmigaOS (and clones)
--------------------
* Fixed virtual filesystem bug that broke mounting of a host path ending in
a ':' or a '/'.
* Faster start-up on OS4 on AmigaONE hardware and on MorphOS (it's no longer
ncessary to perform timing calibration at start-up).
* Improved native AmigaOS graphics driver:
- now works on OS4 update 3
- high/true-colour rendering now supported on AROS
- better speed on MorphOS.
* Emulated SCSI device and hence CD32 emulation now work.
* Added AmigaInput joystick driver for AmigaOS 4.0.
BeOS
----
* Faster start-up on x86 systems (it's no longer necessary to perform
TSC calibration at start-up).
* Re-worked and bug-fixed BeOS graphics driver (P96 emulation not yet
supported).
* New BeOS joystick driver which supports multiple joysticks.
Win32
-----
* Rudimentary support added for compiling with MinGW32 against SDL (and I've
also heard that it works with Cygwin). This is just for fun right now, and
if you want UAE on Windows you're much better off sticking to WinUAE.
Still to do
===========
The following features of WinUAE are not supported:
* Serial and parallel port emulation.
* AHI soundcard emulation.
* Catweasel support.
* OpenGL rendering and graphics filters.
* Snapshots
* Floppy drive sounds.
* Everything else that I've forgotten about.
Known problems
==============
Some significant misfeatures that I know about and am working to fix:
* Only platforms supporting the GTK+ toolkit have a useable configuration
GUI (and the GTK+ GUI is still incomplete).
* 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.
* Autoscroll screens are broken in Picasso96 emulation.
* 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.
* Hard files are limited to 2GB in size.
* Full documentation is lacking.
