WinUAE 4.3.0

WinUAE 4.3.0 (19.12.2019) released.

New features/improvements:

  • GUI high DPI support rewritten.
  • Lagless vsync stability improvements.
  • Added Trojan light gun preset to Game ports panel.
  • On the fly chipset model switching compatibility improved.
  • SPTI CD/DVD access mode now internally emulates all CD audio commands. All other commands are forwarded to the drive like previously.
  • PCMCIA hot swap support improved. (PCMCIA SRAM and IDE needs to be set again if previously configured)
  • My CPU tester detected edge cases, bugs and undocumented CPU behavior updates implemented. (More details in separate CPU tester note later)
  • More compatible partition HDF default geometry calculation if size is 1000M or larger.
  • CD32 pad does not anymore disable joystick second button if both CD32 and 2-button joystick is active simultaneously.
  • Host directory/archive drag and drop to WinUAE window now supports mounting multiple items simultaneously.
  • Debugger disassembler fixes and few very rarely used instructions dissemble now correctly.

Bugs fixed:

  • Disk index pulses were not being generated when disk was being written (Cadaver v0.1 save disk writing)
  • CDTV audio CD playing state restore fixed.
  • A2024 monitor didn’t show full viewable area.
  • 24-bit uaegfx RTG mode had random wrong color pixels in some situations.
  • nrg CD images didn’t load correctly in relative path mode.
  • Graphics glitch in some programs that also depended on display scaling/size (for example Alien Breed 3D)
  • Disk swapper path modifications did nothing while emulation was running.
  • Restoring CD32 or CDTV statefile with CD audio playing: start playing immediately, do not include normal CD audio start delays.
  • Fixed possible crash when PPC emulation stopped emulated sound card audio.
  • Quite special kind of CD32 pad button read code was not emulated correctly.

Other changes:

  • Added separate 68000-68060 CPU tester/validator project based on UAE CPU core generator.
  • Removed all 68020 cycle-exact CPU mode internal idle cycles. It mainly slowed down the CPU too much and didn’t match real world well enough.

New emulated hardware:

  • Archos Overdrive HD (PCMCIA IDE adapter)
  • ICD Trifecta (A500 IDE/SCSI controller)
  • M-Tec Mastercard (SCSI expansion for M-Tec T1230 A1200 accelerator)
  • Scala MM dongles

WinUAE 4.2.1

WinUAE 4.2.1 (16.05.2019) released.

4.2.0 bugs fixed:

  • Picasso IV and uaegfx YUV (video) overlay fixed. Didn’t affect RGB overlays.
  • Reset/restart didn’t reset overlay state.
  • Graphics corruption in some AGA programs (for example Alien Breed 3D).

Old bug fixed:

  • PPC emulation + Picasso IV: some programs had incorrect colors (For example Shogo MAD).
  • A2386SX bridgeboard unreliable/hanging floppy access fixed.
  • Changing accelerator board options (jumpers etc) on the fly didn’t do anything.
  • Fixed hang when attempting to play physical CD32 CD with video tracks.
  • Fixed crash when mounting UAE controller HDF with more than 30 partitions.

WinUAE 4.2.0

  • 68030 MMU emulation will now also create short type bus error stack frames when possible, matching real 68030 behavior.
  • Windowed mode keeps aspect ratio if CTRL is pressed while resizing.
  • Added debugger invalid access logger (memwatch l).
  • Reject Alt+<some key> Windows system menu key shortcuts. Invalid short cut combinations can generate annoying Windows alert sounds.
  • KS ROM selection supports loading and relocation of hunk and m68k elf executables.

  • Minor custom chipset fixes (Small graphics corruption in certain special situations)
  • Moving mouse outside and back to WinUAE window in Magic mouse activated WinUAE window even if some other window was already active.
  • AVI recording with non-standard refresh rate was reset to default if GUI was entered and exited during recording.
  • uae-configuration returned return code 10 even when matching config entry was found.
  • “Add PC drives at startup” enabled and same drive’s root directory also mounted manually: drive was mounted twice. (Introduced in 4.1.0)
  • Genlock transparency didn’t always activate even when genlock emulation was enabled.

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.

  • 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.

  • 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.
