<h1>NAGI v2.07 beta Source</h1>
<b>By Nick Sonneveld</b><br>
<h3>Introduction</h3>
This is the public release of the NAGI source code.<br>
<br>
NAGI (New Adventure Game Interpreter) is a clone of Sierra's own
AGI which they created and used through the 80's to produce a whole
bunch of great adventure games like Space Quest, Leisure Suit Larry
and Kings Quest. NAGI was created by disassembling the original AGI
executable and writing equivalent C code that would run under
SDL which is a free generic library for low-level access
to graphics and audio. It can read both v2 and v3 game data for the
PC.<br>
<br>
I am still supporting and working on NAGI! I just feel it's time to
release the source code as well. If you are working on a similiar interpreter
or a tool to help develop AGI games, then hopefully you'll find some use
in the NAGI source code. The original source was released April 18th, 2002.<br>
<br>
The current source release supports Linux and some some minor bug fixes! Check it out!<br>

<h3>
Systems Supported</h3>
</h3>
<ul>
<li>
Windows - NAGI was originally written for Windows using the SDL Library</li><li>Linux - a new version, ported by Gareth McMullin</li>
</ul>
<h3>Build Requirements</h3>
In order to successfully build NAGI from the provided source code, you will need:<br>
<ul>
<li>gcc - <a href="http://www.mingw.org">MinGW</a> is an excellent compiler for Windows<br>
</li><li>Make - automating compilation (available through cygwin or the ported mingw tools)</li><li>Sed - an attempt at dependancy generation</li><li><a href="http://www.libsdl.org/">SDL Library Headers</a> - NAGI links to this</li><li>SDL Runtime Library - necessary to run NAGI. Usually is provided with SDL Library</li>
</ul>
<h3>How to Build</h3>
Make sure SDL include files are available using #include <sdl/sdl.h><br>
<br>
The mingw tools, sed and make will need to be in the system path. Depending on the operation system you need to type in:<br>
<ul>
<li>"make -f Makefile.win"</li><li>"make -f Makefile.linux"</li>
</ul>
For Windows (since Linux version only has one build)<br>
<ul>
<li>"make -f xx" - compile NAGI and NAGI-console</li><li>"make -f xx nagi" - compile NAGI</li><li>"make -f xx nagi-console" - compile NAGI with console support</li>
</ul>
All files are produced in a directory called "../bin". This is easily changed in the makefile.
<h3>Suggestions</h3>
These are some things that I planned to work on:<br>
<ul>
<li>New save game format to make it less fragile and compatible across other free interpreters</li><li>Save menu, controller and thumbnail info in save games<br>
</li><li>Font scaling</li><li>Clean sound code</li><li>Optimised x1 x2 graphics scale modes</li><li>beeping for agi errors</li><li>GUI to configure NAGI options (using wxWindows?)</li><li>Links with AGI Studio to aid debugging</li><li>MIDI generation</li><li>Ability to split ini keys on several lines</li><li>Screenshots</li><li>Separate ini file in game directory overides main ini</li><li>cache of found games</li><li>After quitting game, go back to game menu</li><li>Dialogue box to enter commands</li><li>Selectable gui backgrounds</li><li>256 colour / palette hacks</li><li>support for Amiga mouse commands</li><li>support for AGInfo's game checksum list</li><li>support early interpreter's sprite handling (fix Donald Duck, AGI Trek, Xmas demo sprite glitches)</li><li>transition screen fades between new rooms</li><li>fix windib support (SDL problem?)</li><li>joystick support<br>
</li><li>patches for copy protection</li>
</ul>
Hopefully that will give you some ideas if you want to hack NAGI.<br>
<h3>Disassembled Code</h3>
Also in another package are files I used for disassembling NAGI. Some
code, before I started writing straight into C, is available here along with
files that are compatible with the early free DOS version of IDA (interactive
disassembler). If you have a legal commercial Windows version, it should
be able to read them in and convert them.<br>
<br>
If any of the disassembled comments looks wrong, it possibly is. I
learnt proper C and how to read assembler from this project so my initial
guesses may be wrong.<br>
<h3>Support</h3>
Send me any emails if you want more information on NAGI or how the source
code fits together. As long as it doesn't get too demanding, I won't
mind answering any questions.<br>
