Box64 v0.3.2 is out today as the newest feature release to this Linux user-space emulator for allowing x86_64 binaries to run on ARM64 (AArch64) Linux devices. Box64 is one of the leading ways for allowing x86_64 games and Steam to be able to run on ARM 64-bit Linux devices.

With Box64 v0.3.2 there is now Box32 added for running 32-bit applications on 64-bit operating systems. Box32 is a build option for Box64 that is disabled by default. This Box32 integration is currently a work in progress but some games are beginning to work on this code path.

The new Box64 release also adds support for native flags via the "BOX64_DYNAREC_NATIVEFLAGS" option for controlling the enabled flags and can lead to a "large speedup on certain cases."

This Box64 update also improves Strong Memory Model emulation, much faster performance with Dynarec when running on RISC-V 64-bit, improves CPUID opcode handling, improves TRAP signal generation and handling, improves some x87 operations, various opcode fixes, new build profiles for Snapdragon 865 and Oryon targets, support for a few more system calls, some additional Vulkan extensions now properly wrapped, and more build system improvements.
