WinUAE v5.1.0 Beta 15 is released. WinUAE is the commodore amiga emulator for Windows. WinUAE 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 680×0 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. WinUAE is a port of the originally written for Unixish systems UAE; but over time, it seems the Windows port, WinUAE has become the best version available on any platform. WinUAE 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 WinUAE is distributed.
