box64 Box64 - Linux Userspace x86_64 Emulator with a twist, targeted at ARM64, RV64 and LoongArch Linux devices

v0.4.0 - box64 Release Notes | AnnounceHQ
What's Changed
This version added many important refactors: the opcode prefix decoder for Dynarec, libGL and Vulkan, the FSGSBASE support, making segments handling easier and faster.
=> Improved compatibility across all architecture, allowing more DRM protected game to run
=> the prefix refactor helped removed lots of redundant source file, simplifying maintenance
=> BOX32 is getting more and more stable, even if still not 100% ok. But Steam is more stable than before, runs on all architecture. And some gameoverlay UI works, on OpenGL games.
