  • Chip memory max 2M (real chipset limit), 8M (UAE only, 24-bit CPU), max 512M (UAE only, 32-bit CPU)
  • Fast memory. 24-bit CPU max 8M, 32-bit CPU max 2G/3.5G (*)
  • Model specific memory regions supported (“Slow RAM”, A3000/A4000 mainboard RAM etc)

*) 64-bit Windows required, 3.5G only possible with 64-bit WinUAE. 32-bit max is about 512M.

Floppy drives

  • 0 to 4 floppy drives supported.
  • Multiple floppy speed options, compatible, 2x/4x/8x or turbo mode (floppy rotation not emulated, as fast as possible).
  • DD and HD drives supported.
  • PC Bridgeboard floppy drives (SD/DD 5.25″ and DD/HD 3.5″)
  • FloppyBridge real floppy drive support.

Parallel port printer

  • Passthrough. Data from Amiga is sent directly to printer. Only works if Amiga native printer driver is available for selected printer.
  • PostScript passthrough. Amiga PostScript printer driver and PostScript printer required.
  • PostScript emulation. Amiga PostScript printer driver, Windows GhostScript installation. Any Windows compatible printer.
  • Epson matrix printer emulation. Emulates 1980/90s de-facto Epson control codes (fonts, positioning, colors, graphics etc..) supported by nearly all programs that had printer support. Any Windows compatible printer.

Serial port

  • Amiga native serial port to host serial port option. Only supports standard 7/8-bit serial protocols, 9-bit serial protocol is not supported by PC hardware.
  • Supports all host serial-port like serial ports, bluetooth adapters etc.
  • Connect two running WinUAE instances with emulated null modem cable.
  • Serial port to TCP socket support.
  • Telnet-like serial port to WinUAE log window support.


  • Amiga native serial port to host MIDI device option. Automatically used when serial port is programmed to 31200 bps speed.
  • Optional MIDI in to MIDI out routing.

UAEGFX Picasso96 compatible RTG (Retargetable graphics) board

  • Configurable 24-bit CPU ZorroII (max 8M) or 32-bit CPU ZorroIII (max 512M) VRAM.
  • Full color depth support, including modes that host OS/hardware don’t support (for example 8-bit, 24-bit and big-endian RGB modes)
  • All native hardware resolutions available.
  • Picasso96 Overlay/PIP supported.
  • Also supports Amiga common modes that host OS/hardware may not support, for example 320×256.

Miscellaneous emulator expansions

  • Host harddrive directory mounted as Amiga harddrive.
  • uaehf.device. Hard disk image support and direct block device support (Physical HD, CF card etc..)
  • bsdsocket.library. Amiga TCP/IP stack that uses host’s TCP/IP stack.
  • uaenet.device SANA-II device driver. SLIRP or WinPCap backends supported.
  • uaeserial.device. Multiport serial device, Amiga side unit x = host serial port COMx:.
  • uaescsi.device. Access host PC optical drives. SCSI emulation and CD audio supported.

All above harddrive options support Amiga automount and autoboot, even under Kickstart 1.2 and older.

CD support

  • Most popular CD images are directly supported: iso, cue/bin, cue/iso/wav, cue/iso/mp3, cue/iso/flac, mds, chd, nrg. (All sector sizes supported, automatic conversion)
  • Compressed images supported, transparent on the fly decompression, no temporary files used.
  • Physical CD/DVD/BD drives supported, including CD emulators that emulate CD/DVD/BD drives.
  • Physical drive audio tracks supported, uses real time digital audio extraction, does not require analog audio cables.
  • SCSI command emulation, including audio track support using digital audio extraction.
  • Hardware ATAPI and SCSI emulation, CD image or drive connected to any hardware emulated IDE or SCSI controller.

CDTV/CD32 special CD features

  • Hardware subchannel (CD+G/CD+MIDI audio CD) emulation.
  • Autodetects CDTV/CD32 media in any physical or virtual drive.
  • CD32 FMV module (VCD player).

File support

Amiga models emulated

Very high compatibility and accuracy:

  • A500
  • A500+
  • A600
  • A1000
  • A2000
  • CDTV

A500 emulation in cycle-exact mode is 100% accurate.

Good compatibility (Cycle-exact chipset emulation, CPU memory accesses are cycle-exact, CPU internal instruction execution speed is not exact):

  • A1200
  • CD32

Fast CPU emulation only, chipset/chip ram CPU accesses optionally cycle-exact:

  • A3000
  • A3000T
  • A4000
  • A4000T
