The user of the emulator would typically load an application into the emulator and use it. The emulator program tries to produce a similar experience as the original Amiga computer did. The emulator will play the same sounds and display the same picture as the original computer did. Modern controllers (e.g. joysticks) differ from those on the original Amiga computer, but the emulator will let the user take advantage of keyboard or modern controllers to use the emulated software.

For software, UAE may use disk images made from Amiga floppy disks or hard drives. UAE also supports mapping host operating system directories to Amiga hard drives. A disk image is a computer file containing the complete contents and structure of a data storage medium or device. ...
Features
UAE is almost a full featured Amiga emulator. It emulates most of its functions: The Original Chip Set (OCS) was a chipset used in the earliest Commodore Amiga computers. ...
Enhanced Chip Set (ECS) is the name used for the enhanced version of the Amiga computers original chipset (OCS). ...
Advanced Graphics Architecture (AGA) was the name used for the improved graphics chipset of the third generation Amiga computers at the beginning of the 1990s. ...
The Motorola 680x0, 0x0, m68k, or 68k family of CISC microprocessor CPU chips were 32-bit from the start, and were the primary competition for the Intel x86 family of chips. ...
The name UAE was originally called the Unusable Amiga Emulator, due to it not even being able to boot, but that name has since become obsolete. The abbreviation is now commonly expanded as "Unix Amiga Emulator". Because the software now runs on other platforms besides Unix, other expansions exist, primarily "Universal Amiga Emulator", "Ubiquitous Amiga Emulator", "Ultimate Amiga Emulator", or even the recursive "UAE Amiga Emulator".

Portability UAE has been ported to many host operating systems, including Linux, Mac OS, FreeBSD, DOS, Windows, RISC OS, BeOS, the Xbox console, and even AmigaOS, where it allows software that requires the Amiga chipset to be run on modern PPC-based AmigaOS machines.

Emulation speed There have been many threads in the past on Usenet and other public forums where people argued about the possibility of writing an Amiga emulator. Some considered UAE to be attempting the impossible; to be demanding that a system read, process and output 100 MB/s of data when the fastest PC was a 66 MHz 486, while keeping various emulated chips (the Amiga chipset) all in sync and appearing as they were supposed to appear to software. Usenet (USEr NETwork) is a global, distributed bulletin board system (BBS). ...
For a long time, UAE was entirely unusable but slowly and step by step, it fleshed out the support of the Amiga chipset and by 1998 was able to more-or-less emulate an Amiga 500 at full speed.
Today, UAE is quite usable, thanks partly to the effort taken to develop it and partly to the big improvements in technology that brought computers many times faster than those UAE was initially run on. Many Amiga games and applications can run smoothly on a Pentium II-era system. The realization that a useful Amiga emulator could be written contributed to an enthusiasm about emulation, which started or speeded efforts to write emulators of the most various, obscure and complicated architectures. Pentium II – front view The Pentium II is an x86 architecture microprocessor by Intel, introduced on May 7, 1997. ...
A major improvement was made in 2000 by Bernd Meyer with the release of a Just In Time compiler, which significantly improved the emulation speed, to the extent that PCs could now emulate some Amiga software faster than any real Amiga. Like all good platform emulators, UAE uses as much of the host's power in native mode as possible. UAE provides a "video card" for the Amiga side of emulation which is tailored for display on the PC hardware, rather than have to go through the complex emulation of Amiga's video hardware. This article is about the year 2000. ...
In computing, just-in-time compilation (JIT), also known as dynamic translation, is a technique for improving the performance of bytecode-compiled programming systems, by translating bytecode into native machine code at runtime. ...
The term native mode is used in computing as follows. ...
Project development There are currently two forks of the original program: In software, a project fork or branch happens when a developer (or a group of them) takes code from a project and starts to develop independently of the rest. ...
- WinUAE, designed to run on Windows
- E-UAE, an experimental tree which ports back some stuff from WinUAE
Today the most active fork is WinUAE, so active and well developed that the E-UAE is actually porting back to POSIX platforms from the Win32 based WinUAE. WinUAE has reasonable compatibility for most software but, as has become a problem with other platform emulators (and projects such as Wine), for some old games WinUAE requires careful configuring or compatibility problems which were evident in the original Amigas can flare up, such as 68000 code causing exceptions on an emulated 68040, just like it would on perhaps an Amiga 4000/040.
