# NAGI Source
**By Nick Sonneveld**
### Introduction
This is the public release of the NAGI source code.
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.
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.
The current source release supports Linux and some some minor bug fixes!
Check it out!
### Current Developers:
* [Nick Sonneveld][1] - Original author
* [Gareth McMullin][2] - Linux port and tweaking
* [Claudio Matsuoka][3] - has pledged to support the project.
* [Ritchie Swann][4] - OS X port, upgrade to SDL2 and various improvements
### License
NAGI's source has been released under the X11 license. This means you can use
the source in any project you want and you do not have to provide the source
if that is your wish. You have to make sure you acknowledge my copyright and
you cannot use my name as an endorsement of something else. No warranties are
implied either.
The X11 license has been deemed to be [compatible with the GPL license][5].
For the full license, check out of the bottom of this page.
### Systems Supported
* Windows - NAGI was originally written for Windows using the SDL Library
* Linux - a new version, ported by Gareth McMullin
### Build Requirements
In order to successfully build NAGI from the provided source code, you will
need a suitable toolchain and a suitable SDL2 library.
Windows - MinGW / MSYS (www.mingw.org/wiki/msys) provides a suitable toolset
MacOS - use MacPorts (www.macports.org)
Linux - most distributions have some way of getting SDL2 installed. See below
### How to Build (Linux/Macos)
* Arch Linux, MinGW : sudo pacman -S libsdl2-dev cmake
* Debian Linux : sudo apt-get install libsdl2-dev cmake
* MacPorts : brew install sdl2 cmake
Then : mkdir build ; cd build; cmake .. ; make
### How to Build (Windows)
* Install Visual Studio 2019 Community
* Download SDL2-devel-2.0.14-VC.zip from https://www.libsdl.org/download-2.0.php
* Decompress SDL2-devel-2.0.14-VC.zip into a directory
* Add support/sdl2-config.cmake to SDL directory
* Open nagi directory in Visual Studio as a cmake project
* Go to Project/CMake Settings for NAGI. Set variable SDL2_DIR to SDL location
* Build!
### Suggestions
These are some things that I planned to work on:
* New save game format to make it less fragile and compatible across other
free interpreters
* Save menu, controller and thumbnail info in save games
* Font scaling
* Clean sound code
* Optimised x1 x2 graphics scale modes
* beeping for agi errors
* GUI to configure NAGI options (using wxWindows?)
* Links with AGI Studio to aid debugging
* MIDI generation
* Ability to split ini keys on several lines
* Screenshots
* Separate ini file in game directory overides main ini
* cache of found games
* After quitting game, go back to game menu
* Dialogue box to enter commands
* Selectable gui backgrounds
* 256 colour / palette hacks
* support for Amiga mouse commands
* support for AGInfo's game checksum list
* support early interpreter's sprite handling (fix Donald Duck, AGI Trek,
Xmas demo sprite glitches)
* transition screen fades between new rooms
* fix windib support (SDL problem?)
* joystick support
* patches for copy protection
Hopefully that will give you some ideas if you want to hack NAGI.
### Disassembled Code
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.
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.
### Support
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.
