WinUAE is a 32-bit Windows version (Win95, Win98, and WinNT only) of the Ultimate Amiga Emulator (UAE). UAE is a collaborative effort between a number of Amiga enthusiasts to create a portable Amiga emulator under the GNU Public License. The source-code for all UAE versions is available, and donated code is always appreciated.
WinUAE allows you to run Amiga software under Windows, including many games, demos, and applications. General compatibility is quite good, and there are a number of enhancements in WinUAE compared to a standard Amiga computer.
