Revolutionize your
retro PC experience.

86Box is a low level x86 emulator that runs older operating systems and software designed for IBM PC systems and compatibles from 1981 through fairly recent system designs based on the PCI bus.



The latest stable version of 86Box is v4.1.1, which was released on March 20, 2024, 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.

Minimum 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.

Getting started
