Versions of the Box86 0.2.6 and Box64 0.1.8 emulators have been released, designed to run Linux programs compiled for x86 and x86_64 architectures on hardware with ARM, ARM64, PPC64LE, and RISC-V processors. The projects are developed synchronously by the same team of developers \u2014 Box86 is limited to running 32-bit x86 applications, while Box64 enables execution of 64-bit executables. The project places significant emphasis on organizing the launch of gaming applications, including the ability to run Windows builds through Wine and Proton. The source code for the project is written in C and is distributed (Box86, Box64) under the MIT license. <\/p>\n

A distinctive feature of the project is the use of a hybrid execution model, where emulation is applied only to the machine code of the application itself and specific libraries. Standard system libraries, including libc, libm, GTK, SDL, Vulkan, and OpenGL, are replaced with versions native to the target platforms. Thus, library calls are executed without emulation, allowing for significant performance increases. <\/p>\n

Code emulation, where native replacements for the target platform are unavailable, is performed using dynamic recompilation (DynaRec) techniques from one set of machine instructions to another. Compared to interpreting machine instructions, dynamic recompilation demonstrates 5-10 times higher performance. <\/p>\n

In performance tests, the Box86 and Box64 emulators significantly outperformed the QEMU and FEX-emu projects when run on Armhf and Aarch64 platforms, and in some tests (glmark2, openarena), achieved performance comparable to running native builds for the target platform. In the 7-zip and dav1d tests, which involve intensive computations, the performance of Box64 ranged from 27% to 53% of the native application performance (in comparison, QEMU showed results of 5-16%, while FEX-emu achieved 13-26%). Additionally, a comparison was made with the Rosetta 2 emulator used by Apple to run x86 code on M1 ARM chip systems. Rosetta 2 achieved 71% performance of the native build in the 7-zip test, while Box64 delivered 57%.

Regarding application compatibility, out of 165 tested games, around 70% worked successfully. About 10% work, but with certain caveats and limitations. Supported games include WorldOfGoo, Airline Tycoon Deluxe, FTL, Undertale, A Risk of Rain, Cook Serve Delicious, and most games from GameMaker. Among the games noted for issues are those based on the Unity3D engine, which relies on the Mono package, the emulation of which does not always work due to the JIT compilation used in Mono, and it has quite high graphical requirements that are not always achievable on ARM platforms. Library replacements for GTK applications are currently limited to GTK2 (replacement for GTK3\/4 is not fully implemented). <\/p>\n
