I further investigated Will's sprite data and discovered the data that stores the position of the individual tiles the sprite graphic consists of. With this data it's now possible to display the sprite graphic in the editor as seen in the following screenshots:
I also discovered the data that holds the time a specific grahic of a sprite animation is shown (example: Will's face down animation has 114 time units with open eyes and 4 time units with closed eyes).
I will continue searching the sprite data to make it possible to display all graphics correctly and make it editable.
UPDATE:
I found some more data and most of the sprite graphics are looking good now!
UPDATE 2:
Found some more data and every sprite animation looks good now :)
