WinUAE v2.1.0 Beta 18 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.

WinUAE v2.1.0 Beta 18 changelog:
- fixed blank RTG fullscreen 8-bit modes if "Match host and RTG color depth if possible" was enabled
- D3D RTG performance improved when whole screen gets refreshed (see below for more info)
- fixed original extended adf (factor 5 images) handling (broke in b11)
- command line parsing heap corruption fix (2.0.0 bug but only caused problems randomly)
- added "minimize when focus is lost" option to misc panel (for example if you want to emulate fullscreen alt-tab in windowed or full window modes)
- always capture mouse when fullwindow mode gains focus (like real fullscreen mode does)
- D3D Null filter does memory copy again because it might be faster (D3D internally uses "doublebuffered" textures if it is told that texture data will be completely rewritten. This prevents GPU stall if previous frame is still being rendered)
