Welcome to Darek Mihocka's Emulators web site. Since 1986 we have pioneered techniques for running Atari and Apple Macintosh software on PCs. Years before Apple made the switch to Intel, our SoftMac emulator was running Mac OS on Dell, Sony, and Gateway PCs in the 1990's.

On August 13th 2007, we started a public beta of the 9th generation of Gemulator and SoftMac, bringing Windows Vista compatibility and 64-bit Core 2 support to our flagship products. The final Gemulator 9.0 release was made on December 1 2008.

Gemulator 9.0 is available as open source.

Emulators.com has contributed code and optimization ideas to numerous open source emulation projects including vMac, Basilisk II, and the Bochs x86 emulation project, the gold standard of PC emulators. Now supporting 64-bit Windows 7 emulation!

The authors of Bochs, Gemulator, and SoftMac presented the case for emulation on June 21 2008 at the AMAS-BT workshop, part of the ISCA 2008 computer architecture conference in Beijing, China. View the Virtualization Without Direct Execution paper and slides.

Follow-up papers were presented at workshops at the 2010 CGO conference in Toronto, Canada, explaining improved Overflow Detection (paper and slides), and at the 2011 ISCA conference in San Jose on Fast Microcode Simulation (paper).

SoftMac 2000 CD-ROM with Fusion PC 3.0

Got an older PC? No problem! Our SOFTMAC 2000 and FUSION PC 3.0 emulators are best suited for use with 486 and Pentium based MS-DOS and Windows 95 systems. Download them and bring new life to your old PC. These emulators use under 1 megabyte of disk space and can be booted from floppy disk, CD-ROM, or the network without requiring prior installation to the hard disk.

SoftMac 2000 CD-ROMs including Fusion PC and free Mac software are available free of charge. Send a self-addressed stamped disk mailer to receive your SoftMac 2000 CD-ROM.

Our site also features the free Xformer Atari 400/800 emulator, and Gemulator, the original Atari ST emulator.


The fundamental design of the microprocessors that power Windows, Mac OS X, and Linux is flawed. 20 years of security promises have fallen flat, leading to consumer frustration and a malware epidemic. How can emulation fix this mess?

Atari ST/STE emulation

Pictured above: the CALAMUS SL desktop publishing program for the Atari ST, running in a virtual Atari ST desktop on Microsoft Windows using the Gemulator 2000 Atari ST emulator.

In the summer of 1992 we launched the world's first Atari ST emulator - GEMULATOR.

Originally designed for 486 processors running MS-DOS, Gemulator 2000 emulator offers fast Atari ST and STE emulation on Windows 95, 98, 2000, and XP.

Atari ST emulation page
Run TOS, GEM, Calamus, Pagestream, GFA Basic, and other Atari ST and Macintosh Plus software on your PC. Find out how with Gemulator 2000.

Atari 8-bit emulation

Pictured above: two virtual Atari 800 windows running on Microsoft Windows using the Xformer 2000 Atari 8-bit emulator. Each virtual Atari 800 is running a completely different program - one is running Atari BASIC, the other is running the well known game STAR RAIDERS.

We released the world's first Atari 400/800 emulator - XFORMER - in January 1987.

Today we offer the free Xformer 2000 emulator which runs Atari BASIC programs and Atari 8-bit video games on Windows 95, 98, 2000, and XP.
