Box86

What Box86 is

Box86 is free, MIT-licensed software for running x86 Linux programs, including games, on Linux systems with other processor architectures such as ARM. It focuses on 32-bit applications and requires a 32-bit little-endian host or a 32-bit userspace subsystem; it does not translate 32-bit programs for a 64-bit-only userspace. On ARM, its dynamic recompiler is described as providing a 5 to 10 times speed boost over the interpreter. Box86 connects programs to native system libraries such as libc, libm, SDL, and OpenGL. The project lists WorldOfGoo, Airline Tycoon Deluxe, FTL, and several GameMaker Linux games as examples that run, and links to a compatibility issue list. Wine is supported, with graphics driver requirements for many games. Steam can run with Box86 but also needs Box64 to be fully usable and uses substantial memory. Vulkan wrapping is available when a system has a 32-bit Vulkan driver; the Pi 4 Vulkan driver does not support DXVK. Configuration can be set in /etc/box86.box86rc and ~/.box86rc, with the user file taking priority. The MIT license provides the software as-is and disclaims warranties and liability.
