While it is akin to comparing minnows to sharks in features, the latest Mac build of DOSBox (0.72) weighs in at 10MiB, compared to VirtualBox 2.0.4's 34.6MiB or VMware Fusion's 247.6MiB.ĭOSBox also has some distinct advantages other than filesize if you just want to run DOS. As I mentioned in the previous post in this mini-series, one of the options for running Windows 3.x on Mac OS X is using the excellent little DOSBox DOS emulator.
