VMachine
Description:
VMachine is a PC emulator, a recreation of a PC in software.
Running on your PC, it creates a completely separate virtual machine.
This allows you to run multiple operating systems concurrently on a single machine, giving you the ability to test software on multiple configurations, perform potentially risky operations in an isolated environment or simply indulge in some retro gaming.
For detailed information about the emulation methods used in VMachine, see the technical information page.
