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. -

teo-emulator
Teo is an emulator of the Thomson TO8 microcomputer
Teo is an emulator of the Thomson TO8 microcomputer for PC, running on MSDOS, Windows and Linux. The compatibility is close to 100% for softwares which don't use non emulated peripherals and don't hold physical protections. In other words, if a software doesn't work on Teo, so probably : 1. it needs the presence of another peripheral than mouse, light-pen, joystick, tape recorder and disks (so it won't run as long as this peripheral is not emulated), 2. its physical protection makes it fail. -
