VirtualBox
Virtualization software for x86_64 hardware
VirtualBox is a powerful open-source full virtualization software that allows a user to run one or more “guest” operating systems simultaneously inside “virtual machines” on a single physical “host” machine. It supports a wide variety of host platforms (Linux, Windows, macOS, Solaris, etc.) and guest OSes, enabling, for example, running Linux on a Windows PC, running Windows Server on a Linux host, or even legacy OSes in a controlled environment. This flexibility makes VirtualBox ideal for developers, testers, sysadmins, or hobbyists who need different OS environments, want to test software across systems, or need isolation for development, sandboxing, or security experiments. VirtualBox offers both a user-friendly GUI as well as a command-line interface and headless mode, making it useful for desktop usage as well as server or automated environments. -

Box64
Linux Userspace x86_64 Emulator with a twist, targeted at ARM64 Linux
Box86 lets you run x86 Linux programs (such as games) on non-x86 Linux systems, like ARM (the host system needs to be 32bit little-endian). Because box86 uses the native versions of some “system” libraries, like libc, libm, SDL, and OpenGL, it’s easy to integrate and use with most applications, and performance can be surprisingly high in some cases. Many games already work without much tweaking, for example: WorldOfGoo, Airline Tycoon Deluxe, and FTL. Many of the GameMaker Linux games also run fine. (There’s a long list, among them are Undertale, A Risk of Rain, or Cook Serve Delicious.) Box64 is the 64bits version of Box86. It is used to run x86_64 binaries on ARM64 (i.e. aarch64) Linux. There are some YouTube channels where you can see box86 and box64 in action: MicroLinux, PILabs, and The Byteman at least. -
