## What it is
Box64 is a Linux userspace emulator that lets you run x86_64 Linux programs, including games, on non-x86_64 systems such as ARM64, RISC-V, and LoongArch. It uses native system libraries (libc, SDL, OpenGL) and a dynamic recompiler (DynaRec) to achieve high performance, and supports running Wine for Windows applications.

## Use cases
- run x86_64 Linux games on ARM64 single-board computers like Raspberry Pi
- execute x86_64 Linux binaries on RISC-V or LoongArch devices
- run Wine and Windows games on ARM64 Linux
- test x86_64 software without x86 hardware
- run Steam games on non-x86 Linux systems

## When to choose
- you need to run x86_64 Linux binaries on ARM64, RISC-V, or LoongArch hardware
- you want to run Wine or Windows games on non-x86 Linux
- you need fast emulation via dynamic recompilation rather than pure interpretation

## When to avoid
- you need full-system emulation or a virtual machine rather than userspace binary translation
- you are on a 32-bit host system (use box86 instead)
- you require perfect compatibility with protected/DRM-heavy software

## Facets
- artifact type: application
- maturity: active
- function: interpreter, compiler, developer-tools
- domain: operating-systems, developer-tools, gaming-tools, cross-platform
- platform: cli
- tags: emulator, binary-translation, dynarec, x86-64, risc-v, loongarch, wine, userspace-emulation, linux, arm64
