Revolutionize your
retro PC experience.

86Box is an IBM PC system emulator that specializes in running old operating systems and software designed for IBM PC systems and compatibles from 1981 through fairly recent system designs based on the PCI bus.


86Box is released under the GNU General Public License, version 2.



The latest stable version of 86Box is v3.1, which was released on December 23, 2021, and is available from our GitHub repository.

We also offer nightly builds, which are built from the latest source code, but may not be as stable and/or optimized as stable builds.

System requirements and recommendations

Performance may vary depending on both host and guest configuration. Most emulation logic is executed in a single thread; therefore, systems with better IPC (instructions per clock) generally should be able to emulate higher clock speeds.

It is also recommended to use a manager application with 86Box for easier handling of multiple virtual machines.

It is also possible to use 86Box on its own with the --vmpath/-P command line option.
