Since Qbasic and QuickBASIC cannot be executed on present-day operating systems directly, two different solutions are subsequently provided for download.
Both are comprehensive software bundles containing all major QBasic and QuickBASIC releases as well as VisualBASIC for DOS.
Virtual Machine (Abbreviation: VM)
An entire operating system, in this case DOS v6.22, will be provided as a guest system in order to run QBasic in its initial environment.
While almost every operating system can be executed in a VM, a DOS emulator supports only a single OS.
This provides the advantage, that even outdated hardware is still supported, e.g. Graphics and Sound Cards.
To this end, DOSBox offers a wide range of options to customize the config file.
Furthermore, there's the option to throttle down CPU speed to simulate outdated processor units.
Also displaying in full screen mode has been integrated flawlessly.
Mounting external folders as standalone drives is another outstanding feature.
Due to advantages mentioned above, DOS emulators are definitely preferable to virtual machines.
However, if you need to run QBasic in its original environment or want to use DOS v6.22 with all its opportunities, the virtual machine is the right choice.
