While 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.
