Box64

What Box64 is

Box64 runs x86_64 Linux programs, including games, on 64-bit Linux systems using ARM64, RISC-V 64-bit, or LoongArch processors. The host must be little-endian and have 64-bit libraries. Box64 uses native system libraries such as libc, libm, SDL, and OpenGL to integrate with the host. Its DynaRec dynamic recompilers support Arm, RISC-V, and LoongArch; the project describes them as 5–10 times faster than using the interpreter alone. Box64 supports Wine64 and Proton, but running 32-bit Windows components requires Box86, except for experimental Wine WOW64 support. It is intended for 64-bit programs; the project points to Box86 or Box32 for 32-bit binaries and describes Box32 as experimental. Users can configure Box64 through system or home-directory configuration files or environment variables. DynaCache is enabled by default, stores generated code under ~/.cache/box64, and can use up to 2 GB by default. The project maintains a game compatibility list and identifies Box64 as MIT licensed.
