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.

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 being able to boot. In its early stages, it was known as Unix Amiga Emulator and later with other names as well. Since none of the popular expansions fit any more, the acronym no longer stands for anything, and the software is simply known as UAE.
Portability UAE has been ported to many host operating systems, including Linux, Mac OS, FreeBSD, DOS, Microsoft Windows, RISC OS, BeOS, the Xbox console, and even AmigaOS and AROS, where it allows software that requires the Amiga chipset to be run on 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 Internet discussion system that evolved from a general purpose UUCP network of the same name. ...
For a long time, UAE was almost entirely unusable but slowly and step by step, it fleshed out its support of the Amiga chipset and by 1998 was able to more-or-less emulate an Amiga 500 at full speed.
Today, UAE is 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 expected to 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 increase in enthusiasm about emulation, which started or speeded-up efforts to write emulators for other and often less popular computer and electronic game 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 use of Just-in-time compilation, which significantly improved the emulation speed, to the extent that average PCs could now emulate some Amiga software faster than any real Amiga. UAE can use as much of the host's power in native mode as possible, or balance it with other requirements of the host OS, or to accuractely reflect the original speed, depending on a user's choice. UAE also provides an RTG-compatible "video card" for the Amiga side of the emulation which is tailored for display on the host hardware, so as not to be limited to the emulation of the original Amiga video hardware. 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 main 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, designed to run on other platforms
Today the most active fork is WinUAE, so active and well-developed that the E-UAE is actually porting back to POSIX platforms from WinUAE. WinUAE has reasonable compatibility for most software but, just like a "real" Amiga, for some old games it requires careful configuration in order to match the originally-supported hardware. For example, 68000 code could cause an exception on an emulated 68040, just like it would perhaps do on an Amiga 4000/040.
