Box86
What it is
Box86 is free, open-source software for running 32-bit x86 Linux applications on Linux systems with a different processor architecture, including ARM. It translates programs at runtime and connects them to native system libraries such as libc, libm, SDL, and OpenGL. On ARM, its dynamic recompiler is described as providing a 5 to 10 times speed boost over the interpreter. 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, though many games require particular graphics drivers. Steam can run with Box86 but also needs Box64 to be fully usable and uses substantial memory. Vulkan wrapping requires a 32-bit Vulkan driver; the Pi 4 Vulkan driver does not support DXVK. The host must provide a 32-bit little-endian system or a 32-bit userspace subsystem, because Box86 does not translate 32-bit programs for a 64-bit-only userspace. The project describes Box86 as the legacy 32-bit version of Box64. It is MIT licensed; the license provides the software as-is and disclaims warranties and liability.
For and against
For
- Runs 32-bit x86 Linux applications on non-x86 systems.
- ARM dynamic recompilation is described as 5 to 10 times faster than interpretation.
- Uses native system libraries including SDL and OpenGL.
- Supports Wine and Vulkan wrapping with a 32-bit driver.
Against
- Requires a 32-bit little-endian system or userspace subsystem.
- Steam also needs Box64 to be fully usable.
- Steam uses substantial memory.
- Vulkan wrapping requires a 32-bit Vulkan driver.
The verdict
Box86 provides a way to run selected 32-bit x86 Linux software on other Linux architectures, subject to host and driver requirements. Its MIT license disclaims warranties and liability.
Who it suits
Box86 is for Linux users who need to run 32-bit x86 applications on another processor architecture, including ARM. It may suit users whose host already has a 32-bit system or userspace subsystem.
