Box86 vs Porting Kit

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.

Porting Kit is a free macOS application that uses Wineskin technology to install games and apps compiled for Microsoft Windows. Its instructions cover installing games from sources including GOG, Steam, Origin, Uplay, GamersGate, and CD/DVD. For Steam ports, Porting Kit can install the Windows Steam client on the Mac, after which users sign in and download games. The download page offers Porting Kit 7 for macOS 12.0 and later, and the maker says Apple Silicon support is growing with newer engines and macOS versions. The download page recommends watching a tutorial before installing game ports. The maker does not guarantee that a port will work on a particular computer and recommends checking its video card ranking. The terms say the app should be used to install legitimate app copies, with an exception stated for abandonware. Ports are for personal use; distribution requires the maker's approval. The terms also say the app may collect video card and macOS details for rankings and Google Analytics, while stating it does not obtain or share other information from the Mac.
