Host: the system/computer that runs the emulator.In a nutshell: DOSBox has been designed to run old DOS applications and games in a fairly easy way, in any host system. (there are videos of DOSBox running inside Symbian Nokia phones) VirtualBox uses virtualization, which means it requires a host CPU of the same architecture of the guest system.ĭOSBox is a full emulator, all CPU instructions have been re-implemented in C, and it can run on any hardware. If you attach that disk to your VM, you should be able to directly access it, e.g.: VBoxManage internalcommands createrawvmdk -filename /home/user/vbdisks/cd. It also has some features to emulate old networking hardware (such as dial-up modems and IPX network) over TCP/IP. The is no option with the GUI to do it but on the command line, you can create a pseudo disk image (vmdk) that refers to a physical disk. It doesn't require a virtual harddrive image, as it can access host directories directly (after mounting a directory as a virtual drive - this is only possible because DOSBox also emulates the operating system). The objective is to run DOS applications as easy as possible. All you have to do is set up a virtual machine, install the version of Windows on it that you need, and then you can run the game in that. You can only access a host directory from the guest system through SMB sharing (over a virtual network).ĭOSBox is a 16/32-bit x86 emulator that already comes with a DOS-like operating system pre-installed. On Windows, you can also use the free VirtualBox software. The guest operating system is fairly "isolated" from the host. It doesn't come with any operating system (you need to install one). VirtualBox is a general-purpose desktop virtualization software, and nothing else.
