How do I display face graphics?

There is a built-in face graphics system as of Base System (Sample Game Engine) Ver. 1.26. It is used as follows.

1. Open System Database Type 24: Face Graphics, and in Data #2 and onset up the face graphics you want with “Face Graphic File.”
2. In the first line of a “Show Message,” use the notation “@2” to change face graphics.
   (An @ followed by the number of the face to use)
   * Face Graphic #0 displays text without a message window,and #1 displays text with only a message window and no face.

Example: Displaying Text With Face Graphic 2 in “Show Message”
