Box86 vs CrossOver

Box86 runs 32-bit x86 Linux programs on Linux systems using other processor architectures, including ARM. It translates programs at runtime and connects them to native system libraries such as libc, libm, SDL, and OpenGL. The host must provide a 32-bit little-endian system or a 32-bit userspace subsystem; Box86 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. The project names WorldOfGoo, Airline Tycoon Deluxe, FTL, and several GameMaker Linux games as examples that run, and links to a GitHub issue list for compatibility information. Wine is supported, though many games require 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. Box86 is the legacy 32-bit version of Box64 and is free under the MIT license, which provides the software as-is and disclaims warranties and liability.

CrossOver translates commands from Windows applications so many can run on macOS or Linux without a Windows emulator or Windows OS license. It is presented for productivity software, utilities and games, and advertises one-click installation, desktop integration and running apps without rebooting. CodeWeavers says the Linux version avoids Windows or virtual-machine overhead and integrates with Linux. Compatibility is incomplete: some applications may have reduced functionality or may not run. The Compatibility Center collects user reports about application behavior. CrossOver supports Intel and Apple Silicon Macs, as well as Linux PCs. The Mac version requires at least 1 GB of free disk space and does not run on iPads or iPhones; Linux has specified hardware, distribution and software dependencies. A fully functional 14-day trial costs nothing, requires no credit card and starts at first launch. CrossOver + costs $74 a year, including 12 months of phone and email support, upgrades and bug fixes, and Preview access. CrossOver Life costs $494, paid once, with lifetime upgrades, bug fixes and support. CodeWeavers says 95% of the Wine code it develops for CrossOver is released back to the Wine project.
