WHAT IS IT?
===========

Grackle is a dumper and player for adventures written using the Graphic
Adventure Creator. 
At the moment it supports games from the following systems:

* Spectrum (in .sna format)
* CPC (as extracted files with the AMSDOS header from a disk image or as a .sna)
* BBC Micro (as the raw datafile extracted from the disc image, usually called
$.DATA)

bbc-grackle-draw.c is included in this version, this is basic messing code to
redraw the graphics on the BBC Micro from the graphics data file (usually
$.GDATA).
The BBC Micro used a different format than other platforms.
The image drawing code is very basic and there will be errors in the output.

WHY IS IT?
==========

This can be useful if you are going to remaster an old adventure or 
gain new knowledge about internals of games.

HOW TO USE IT?
==============

Command line syntax:

grackle [-p|-l] [-s room] file

-p = play game (default)
-l = list game
-s = provide a start room

BBC Micro games aren't quite working yet; the high profile conditions don't seem
to quite work.

(Sinclair ZX Spectrum)
======================

1. Choose a game from List of games created using The Graphic Adventure Creator
and download it.
   (for example Cricket Crazy by The Dreaming Djinn)
   Public Domain:
https://archive.org/details/Cricket-Crazy_1988_The_Dreaming_Djinn
   
2. Run your Speccy emulator and load it.

3. Save memory dump as game.sna

4. Use grackle -p game.sna for Play game

5. Use grackle -l game.sna > game.txt for get the source code of the game as
text-file

(Amstrad CPC)
