As you've seen, the main program file for SpiritWars installs
all of the thumbnail (small) images of the artwork associated with each spirit in the game. You do not need the larger versions of
the images in order to play the game.
However, when you view the detail screen that shows the attributes of an individual spirit
(either in the game or while
working in the Dungeon Editor), if you have the larger
versions of the images they will be displayed.
The full set of images for spirits currently included in the game represents
about 150 megabytes
of images. We obviously couldn't provide these as part of the installation program
you downloaded.
These optional images are available on a CD-ROM.
