WinUAE 4.1.0

WinUAE 4.1.0 (06.12.2018) released.

PC Bridgeboard (A1060 Sidecar, A2088, A2088T, A2286 and A2386SX) emulation rewrite:

  • Emulation core replaced with PCem. Compatibility has improved greatly, for example Windows 3.x enhanced mode, DOS extenders and Windows 95 are now fully working.
  • Bridgeboard built-in CGA emulation graphics corruption fixed.
  • A2386SX VLSI chipset memory remapping, shadowing and EMS fully supported.
  • Cirrus Logic emulation PC compatibility improved, 2M VRAM, linear frame buffer and blitter support.
  • PC Speaker emulation (PCem)
  • Sound Blaster emulation (PCem, various models)
  • Serial mouse emulation (PCem)
  • SCSI adapter emulation (Rancho Technology RT1000B)

Other updates:

  • AGA hires/superhires horizontal pixel positioning and borderblank horizontal single hires pixel offset fully emulated. Optional because it requires much more CPU power and it is rarely needed. DIWHIGH H0/H1 AGA-only bits emulated.
  • AGA FMODE>0 undocumented features implemented (BPLxDAT, SPRxDAT CPU/copper accesses, bitplane modulos that are not integer divisible by fetch size)
  • Added new misc option which captures mouse immediately when windowed/full-window winuae window is activated.
  • 68030 MMU emulation compatibility improved.
  • Paula disk emulation GCR MSBSYNC support added (Alternate Reality protection track).
  • Added quick search and quick directory select to Configurations panel. Link and autoload moved to Advanced information panel.
  • Added history list to config file name edit box and to statefile path string box.
  • Added vertical offset option to D3D scanlines.
  • 64-bit version didn’t support 64-bit unrar.dll.
  • 68030/040/060 with data cache emulation but without enabled MMU emulation: force Chip RAM as non-data cacheable.
  • Magic mouse Windows cursor to Amiga mouse sync partially fixed.
  • Window corners now work as drag’n’drop hot spots for different floppy drives. (top/left=0, top/right=1, bottom/left=2, bottom/right=3).

Bug fixes:

  • 68020 + memory cycle exact hung the emulator in some situations.
  • Reading CIA interrupt status register in a very tight loop generated spurious interrupt(s) in certain situations.
  • Softfloat mode with unimplemented FPU emu ticked didn’t disable 68040/060 unmasked interrupts, confusing 68040/68060.library and possibly causing it to return incorrect values.
  • Some CHD CD images didn’t mount correctly.
  • uaehf.device HD_SCSICMD didn’t set scsi_SenseActual. Also set io_Actual=30 (=sizeof(struct SCSICmd))
  • If config file had KS ROM path/file that didn’t exist, it was replaced with non-existing <original path>../system/rom/kick.rom path or was not correctly fixed with valid path.
  • NCR53F94 SCSI chip emulation DMA counter fix (affected for example Blizzard SCSI Kit)
  • Very large directory harddrives returned halved used/free space.
  • Fixed multiple problems with screenshots and video recording from hardware emulated RTG board.
  • Filter panel scanlines work now correctly in multimonitor mode.
  • Crash fixed if more than one non-Paula audio stream was active. Included emulated sound cards, also CD audio if “include” option ticked.
  • NE2000 PCMCIA and NE2000 bridgeboard didn’t support custom MAC and network mode selection.
  • Fixed hardware emulated graphics board hang with Picasso96 if board supported vblank interrupts and RTG board refresh rate mode was not Chipset.
  • Fixed statefile crash when saving statefile while disk operation was active and disk image included bit cell timing information.

Bug fixes (Introduced in 4.0.0/4.0.1):

  • Display port adapters that needed genlock transparency data (FireCracker, HAM-E, OpalVision, ColorBurst) didn’t work correctly since 4.0.0.
  • Display port adapters didn’t work in multimonitor mode.
  • Blitter statesave with blitter active: log window opened and listed few lines of blitter debug information.
  • Some programs caused continuous flood of “blitter is active, forcing immediate finish” log messages.
  • CTRL+F11 quit ignored new “Warn when attempting to close window” option.
  • 68020/030 more compatible/cycle-exact mode statefiles didn’t always restore properly.

New emulated hardware:

  • CSA Twelwe Gauge (A1200 68030 accelerator + SCSI controller)
  • AccessX/Acetec IDE controller.

WinUAE 4.0.1

WinUAE 4.0.1 (16.07.2018) released.

4.0.0 bugs fixed:

  • Enabled “Minimize when focus is lost” option caused crash in some situations.
  • 64-bit FPU mode always changed back to 80-bit if config file was loaded.
  • 80-bit native FPU mode FREM and FMOD returned wrong results.
  • RTG statefile restore didn’t restore screen state completely.

Other bugs fixed:

  • “Minimize when focus is lost” incorrectly activated when switching modes in some situations.
  • “Minimize when focus is lost” minimized main emulation window when GUI was open and main window lost focus.
  • If CPU panel FPU mode select menu was active and then some other panel was opened: JIT was switched off.
  • CD audio play from real/virtual CD (not from directly mounted image file) didn’t restart correctly if audio settings changed.
  • Only some emulated SCSI controllers flashed CD led when emulating a CD drive.
  • input.keyboard_type was always read as Amiga keyboard. If PC layout was set as default, keyboard layout was read incorrectly from config file.
  • Amiga reset during active RTG rendering in RTG Multithread mode could have caused a crash.
  • RTG Multithread mode display refreshing was unreliable in 8-bit modes when palette changed.
  • Finally fixed corrupted drag and drop graphics in Harddrives and Disk Swapper panel.
  • When inserting previously connected USB input device, previous device type (Gamepad, CD32 pad etc) and autofire mode (if any) was not restored.
  • Clipboard sharing could have attempted to transfer data to Amiga side after program had taken over the system, possibly overwriting memory.

New features:

  • Environmental variables (%variable%) in paths are not anymore resolved immediately when config is loaded but only when needed without modifying original path, preserving original path if config file is saved again.
  • Added full statefile absolute/relative path support. Loading statefile will restore correct paths even if absolute/relative path mode was changed after saving the statefile.
  • D3D9 and D3D11 VSync mode (both lagless and standard) 100/120Hz support with optional black frame insertion.
  • 68060 FPU was not disabled after soft reset if 68060 was configured without emulated 68060 accelerator board, causing reset loop.

New emulated expansions:

  • QuikPak 4060

WinUAE 4.0.0

WinUAE 4.0.0 (20.06.2018) released.

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 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 harddrives 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 harddrive 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 didn’t have any connected SCSI devices.
  • Direct3D11 fullscreen mode didn’t 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 exact to cycle-exact mode stopped emulation in certain situations.
  • Fixed E-Matrix accelerator board RAM selection.
  • If CD was changed and system was reset during change delay, drive become empty and new CD was never inserted. Mainly affected CD32 and CDTV.
  • Reset when uaescsi.device CD was mounted caused memory corruption/crash in certain situations.
  • Code analyzer warnings fixed (uninitialized variables, buffer size checks etc..)
  • Old JIT bug fixed: many CPU instructions didn’t set V-flag correctly. (Aranym)
  • Inserting or removing USB input device caused crash in some situations.
  • Softfloat FPU edge case fixes (FABS, FNEG with infinity, logarithmic instructions with NaN)
  • Decrease/increase emulation speed input events didn’t do anything.
  • Toccata audio was not fully closed when reset/reset and caused crash if new config was loaded and started.
  • Removed forgotten, useless and obsolete “The selected screen mode can’t 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.

New emulated expansions:

  • C-Ltd Kronos

WinUAE 3.6.1

WinUAE 3.6.1 (04.03.2018) released.

3.6.0 bugs fixed:

  • Crash when running on first Windows 10 release version (build 10240) .
  • D3D11 mode fullscreen to/from windowed mode change crashes/blank screens.
  • D3D11 mode on screen leds on the fly on/off switching.
  • D3D11 mode screenshot via GUI button didn’t work.
  • Floppy sound type selection was not loaded correctly from config file.
  • It was not possible to create “DOS” file names like “AUX” to directory filesystem.

Older bugs fixed:

  • Floppy sound used incorrectly empty drive volume level in certain situations.
  • PPC emulation interrupt handling rewrite, fixes for example hang/crash problems with NE2000 based network adapters under OS4.
  • Not all Advanced chipset options reset when compatible checkbox was ticked.
  • Autoscale ignored small vertical display areas in very top of display in some situations.
  • Fixed random crash when at least one Input panel custom event string was set, Restart was clicked and then emulation was started again.
  • Blizzard SCSI Kit IV (possibly others) SCSI phase error in certain situations.
  • Added better validation to clipboard sharing IFF parsing to prevent crashes if data is truncated.
  • -joyport2 -config entry incorrectly used port 3 slot.
  • Game Ports panel selected Custom input mapping reverted to none in some situations.
  • Restart didn’t completely free configured emulated network cards.
  • Other misc bugs fixed.

New features:

  • OCS/ECS only BPLCON2 undocumented feature: “illegal” PF1 or PF2 value is now accurately emulated in dual playfield mode.
  • If selected D3D11 fullscreen refresh rate is “default”: always prefer highest supported refresh rate.
  • Optional threaded emulated RTG VRAM to host OS surface color space conversion/copy.
  • Added “Identity” checkbox to Add harddrive panel. If ticked and ATA identity can be read (Direct IDE connection, compatible USB adapter): real ATA identity data is used in emulated ATA device instead of generic UAE generated and drive appears exactly as it does in real hardware (identical name, geometry etc).
  • CHS-only IDE drives can now be mounted in emulation and they appear with real size and geometry when using USB adapters that allow identity read but does not support CHS (like common JMicron based adapters).

New emulated expansions
