While [1]Fex-Emu has been getting a lot of attention lately for being Valve-sponsored and powering the upcoming Steam Frame, Box64 continues making progress as another great open-source project for running x86_64 Linux binaries on AArch64 Linux as well as an eye on other architectures like RISC-V.

The Box64 v0.4 emulator is out today with improvements to benefit OpenGL and VUlkan usage, improved compatibility across all architectures, opcode prefix decoder work for Dynarec, and more.

The Box64 v0.4 release announcements note that more Digital Rights Management (DRM) protected games are working with Box64:

"Improved compatibility across all architecture, allowing more DRM protected game to run"

The 32-bit version Box32 is also enjoying more success with Steam:

"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."
