Jill of the Jungle is the first version of the engine which would go on to power Xargon. Allen Pilgrim wrote the code for Xargon and did not use the 'Jill of the Jungle' engine. It supports CGA, EGA and VGA graphics by way of "colour maps", which dictate the CGA and EGA colours to be used to display each of the possible 256-colours of a given image. This way only a single 256-colour image is supplied, rather than a different image for each display.
Jill is also unique in that it is one of a very small number of games that include a level editor, albeit an undocumented one. See the tutorial for more details.

Episode selection screen
Some versions of Jill come bundled with an episode loader executable which displays an interactive screen that allows the player to select from three episodes (if present) and ordering info. The executable contains large amounts (About 90%) of raw data used to display the screen itself and the ordering info if selected. The selection screen uses a single image but various areas of it are faded in in sequence when the executable runs.
The ordering info uses the Crunched Screen Image format.
| Data | Location | Size |
|---|---|---|
| Screen | 04E7 | 64'000 bytes |
| Screen palette | FEE7 | 768 bytes |
| Order info | 12AF2 | 23'630 bytes |
Notes
- Since the level files are used for a lot of different things, you can e.g. swap INTRO.JN1 and 1.JN1 and then when you load the first level you'll be playing the intro screen. The demo and help screens can be accessed in the same way.
- You can also press Ctrl+P on the main menu to play the intro level, and Ctrl+E to enter the level editor.
