I let you watch
this video explaining how to install Win95 (CD version) in VirtualBox. You need to download
VirtualBox, a
bootdisk and an ISO of Win95 (unless you already have a CD).
When the machine is fully configured, you have to go back to the VM's settings --> Storage and put MSWDOF.iso in the virtual drive. Then you should be able to install the game inside the VM.
Ask here if you need further details or if you come across a problem.
