Version 4.0 of WinUAE has been released. This Windows port of the UAE Amiga emulator is able to perfectly emulate a Commodore Amiga. All models, from the very first Amiga 1000 to the Amiga 4000, are supported. Keep in mind that WinUAE is delivered without kickstart , so to speak the bios / firmware of an Amiga, or other software. More information can be found on the support forum . WinUAE runs on Windows XP and higher, and the download is less than 10MB. For a kickstart and programs Amiga Forever is a possible solution, with prices starting from 10 euros. In this edition the following changes and improvements have been made:

New major features:

Beam Racing Lagless VSync which reduces input latency to sub-5ms. Replaces old Low Latency Vsync. (Use 1-2 slice Lagless VSync to match old Low Latency VSync behavior)
Virtual multi monitor support. Each virtual Amiga video output connector (Video port graphics adapter, RTG boards) can be connected to a separate WinUAE window, emulating real hardware being connected to more than one physical monitor.
Debugger supports running Amiga executables from shell, adds symbol and gcc stab debugging data support, loads executable to special reserved address space which enables detection of any illegal accesses byte accurately and more. ( Details )
Host mode FPU emulation mode is finally full extended precision (80-bit) capable. It is also fully JIT compatible.
New other features:

Overlay graphics led (power, floppy etc) support.
Close confirmation option added to misc panel.
Default WASAPI audio device automatically follows Windows default audio device.
Directory hard drives now use uaehf.device as a fake device driver (replacing non-existing uae.device), for example programs that query extra information (like SCSI Inquiry data) now get valid data.
Directory filesystem hard drive fake block size dynamic adjustment now starts from smaller disk size, workaround for WB free space calculation overflow when partition is larger than 16G.
Harddrive imager now also supports native (mainboard / expansion board) IDE connected CHS-only drives.
Disk swapper config file data is restored from statefile.
Cirrus Logic RTG horizontal doubling support, keeps aspect ratio in doublescan modes.
Action Replay II / III state file support improved.
Windowed mode resize enable / disable option.
CDTV SCSI and SRAM options moved to Expansions.
3.6.x bug fixes:

WD33C93 based SCSI controllers hung the system if controller did not have any connected SCSI devices.
Direct3D11 fullscreen mode did not open if monitor was connected to non-default GPU. (For example laptops with Intel and NVidia GPU with NV GPU connected to external monitor)
Direct3D11 fullscreen ALT-TAB refresh problems and other D3D11 fixes.
68030 MMU PLOAD was broken (Caused Amiga Linux crash at boot).
Older bugs fixed:

On-the-fly switching from non-cycle exactly to cycle-exact mode to stopped emulation in certain situations.
Fixed E-Matrix accelerator board RAM selection.
If CD was changed and system was reset during change delay, CD was never inserted. Mainly affected CD32 and CDTV.
Reset when uaescsi.device CD was mounted due to corruption / crash in certain situations.
Code analyzer warnings fixed (uninitialized variables, buffer size checks etc ..)
Old JIT bug fixed: many CPU instructions did not set V-flag correctly. (Aranym)
Inserting or removing USB input device causes crash in some situations.
Softfloat FPU edge case fixes (FABS, FNEG with infinity, logarithmic instructions with NaN)
Decrease / increase emulation speed input events did not do anything.
Toccata audio was not fully closed when reset / reset and because crash was set and loaded.
Removed forgotten, useless and obsolete “The selected screen can not be displayed in a window, because ..” check.
Fixed WASAPI Exclusive mode audio glitches when paused / unpaused.
Paula audio volume GUI volume setting was ignored if audio mode was mono.
