4.3 / 21-12-2019



WinUAE is a Commodore emulator for Windows:

  • High accuracy and compatibility for A500, A500+,  A600, A1000, A2000, CDTV

  • Good compatibility (Cycle-exact chipset emulation, CPU memory accesses are cycle-exact, CPU internal instruction execution speed is not exact) for A1200 and CD32

  • Fast CPU emulation only (chipset/chip ram CPU accesses optionally cycle-exact) for A3000, A3000T, A4000 and A4000T. To see all features, follow this link

Extension packages & Miscellaneous utilities 

  • PPC CPU core plugin, 1.5.1+ Direct3D Pixel Shader filters, Improved drive sounds, Portaudio library

  • UAEUNP 0.8 to extract Amiga based disk images and archive


Windows: XP SP3 32-bit+


CPU: SSE2 capable

GPU: For Direct3D11 - Windows 7: SP1+

          For Direct3D9 - June 2010 DirectX 9 redistributable required

Most Recent Changes!

  • 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
