A typical command line would be:

vms tetris.vms

Something more complex:

vms -s:320 -1 tetris.vms

The DOS port uses a file called vmu.pcx as a background image. If you want to change the image (which must be a PCX file) use a command line such as:

vms -I:newimage.pcx tetris.vms

If you use a different image, chances are that your palette won't match the palette used in the original vmu.pcx. The two command line options -B:nnn and -F:nnn can be used to change the colour index used as foreground and background colours:

vms -I:newimage.pcx -F:255 -B:0 tetris.vms
