Box64 0.3.8 Brings DynaCache As Disk Cache For Generated Native Code From x86_64

Written by Michael Larabel in Linux Gaming on 13 October 2025 at 08:23 AM EDT. 5 Comments
Box64 0.3.8 is now available for this x86_64 user-space emulator for Linux that allows ARM64 and RISC-V 64-bit and LoongArch 64-bit systems to enjoy running x86_64 games and applications. Box64 along with the likes of FEX-Emu are the leading options for those needing to run x86_64 programs on ARM64 and elsewhere.

Most notable with today's Box64 0.3.8 release is introducing DynaCache. Box64's DynaCache is a disk cache for generated native code. With this release it's not enabled by default but can speed-up the loading of programs for already-cached generated native code from running the x86_64 programs previously. Beyond faster start-ups, DynaCache can also help avoid some "runtime hiccups" too.

Box64 0.3.8 also has better Box32 compatibility, Unity 3D games on Wayland are now working, Volatime Metadata is now fully supported, and continued work around AVX support on RISC-V 64-bit and LoongArch64 architectures.
