Overview - What is UAE?
UAE is a mostly complete software emulation of the hardware of the Commodore Amiga 500/1000/2000.
A Commodore Amiga, for those who don't know, is a 16/32 bit computer system based on the Motorola 680x0 CPU and a few specially designed custom chips that provide very good graphics and sound capabilities. Its first incarnation, the A1000, appeared in 1985, followed by the highly successful A500 and A2000 models.
UAE is written for Unixish systems; it is developed on a Linux machine but it should compile and run on any half-recent Unix-like operating system. It has also been ported to a wide variety of machines and operating systems, including DOS, Windows 95/NT, MacOS, RiscOS, BeOS and NextStep.

UAE is free software: you are welcome to distribute copies of it and/or modify it, under certain conditions. There is no warranty of any kind for UAE. For more details concerning these issues, please read the GNU General Public License, which describes the terms under which UAE is distributed.

Features
UAE emulates:

Required Soft- and Hardware
You need a computer running one of the supported operating systems. As a general rule, the faster your computer is, the better.
If you want to compile the source code yourself, you need an ANSI C compiler.

Apart from that, you need a Kickstart ROM image file for most purposes. Software to transfer that from your Amiga to your PC is included in the source distribution, as well as documentation on how to use it.

Please note: The Kickstart ROM is copyrighted by Amiga International and we may not distribute it. Officially licensed Amiga ROM and OS files are available both for download and on CD-ROM as part of Cloanto's Amiga Forever package, which includes Kickstart files up to v3.1 (the latest version).

You also need software to run on the emulator. Like a piece of hardware, an emulation by itself is not very useful.

Download UAE Source
The latest version is 0.8.23. As 0.8.23 is pretty stable, there will likely be a UAE 1.0 in near future.

Download UAE Binaries
Binary versions of UAE for Unixish systems: Other versions may appear on the UAE ftp server.

Patches for UAE & New Stuff
These are additional patches for UAE which are either not ready for inclusion into the main version yet because they are still being tested, or because they are quite complex and are still being evaluated for correctness. Use at your own risk, but do report any interesting test results. Lester Barrows has set up an UAE patches page. Here you'll find patches for UAE that are not (yet) included in the mainstream versions.
If you want your patches being announced here, just send an email to Stefan Reinauer with the patches attached.

Software useful with UAE
There are other pieces of software that can be very useful when used together with UAE.

Test Software

Other Amiga Emulations
The first Amiga "emulation" is a hoax program for MSDOS that displays the "hand holding a disk" picture used in old Amiga ROMs and tortures the floppy stepper motor a bit. You can download this hoax program, but we make no guarantees that it does no harm to your system. It could be a virus (it's probably safe, but I haven't disassembled the thing, and it's a bit large for a GIF viewer. This isn't quite the original: for copyright reasons the Kickstart 1.2 ROM which was contained in the EXE file was removed. It runs fine even without it ;-)
After that, a very nicely done GIF file appeared: NXAmiga.gif, which is also a hoax, but a much better one.
Then came UAE...
These days, UAE is no longer alone in the world. It now has a fellow: Fellow, which is another Amiga emulation written by Petter Schau. As it seems, Fellow is now maintained by Dominik Schmidt and Torsten Giebl. It runs under DOS and is generally quite a bit faster than UAE, but does not yet emulate the hardware as completely as UAE does. Like UAE, Fellow has been ported to other platforms. Get the Windows port of Fellow. More information can be found on the WinFellow homepage. There's a port of Fellow to Unix based platforms using X11 from Riot777. Have a look at xfellow.sf.net.

UAE Discussion
Gustavo Goedert has set up a UAE web discussion board for related discussion.
There is an official IRC channel for UAE, on irc.freenode.net #AmigaUAE.
