The Magnetic Scrolls adventures were as well known for the quality of their graphics as of their text. The Magnetic interpreter supports graphics files (".gfx") which can be created from the Amiga releases. You'll probably want to download the graphics files from the Magnetic Scrolls Memorial site.
The format of Magnetic's graphics files differs between the original and Magnetic Windows ("Wonderland" and "Collection Volume 1") releases, therefore a story file created from an original release cannot be used with a graphics file from a Magnetic Windows release, and vice versa.
The extraction tools have not been ported to Java yet, so if you wish to extract the graphics files yourself, please refer to one of the system dependend ports which includes the tools, e.g. Magnetic for Windows.
