SDLPAL
======

SDLPAL is an SDL-based reimplementation of the classic Chinese-language RPG
"Xian Jian Qi Xia Zhuan" (also known as PAL or Legend of Sword and Fairy).

gpl.txt for details.

Many of the ideas of this program are based on documents from PAL
Research Project (https://github.com/palxex/palresearch), and portions of the
code are based on the work done by Baldur and louyihua.

The getopt.c file is based on source code in OpenBSD.

The resampler code is based on the code in Kode54's foo_input_adplug project
(https://github.com/kode54/foo_input_adplug).

This program made extensive use of the following libraries:

SDL (http://www.libsdl.org/)
Adplug (http://adplug.sourceforge.net/)
SDL_mixer (http://www.libsdl.org/projects/SDL_mixer/)
libmad (http://www.underbit.com/products/mad/)
libogg & libvorbis (http://www.vorbis.com/)

And some of the OPL simulation cores this program used are from the DOSBOX
project (http://www.dosbox.com).

Please see authors.txt for additional authors.

This program does NOT include any code or data files of the original game,
which is proprietary and copyrighted by SoftStar Inc.


COMPILE UNDER WINDOWS
=====================

The following compilers/IDEs are supported under Windows:

1) Microsoft Visual Studio 2013 or higher (official)
2) Dev-C++ 4.9.9.2 (unofficial)
3) Open Watcom 1.7 (unofficial)

To compile, open the respective project file (sdlpal.sln, sdlpal.dev, or
sdlpal.wpj). You need to have SDL 2.0 development files installed.


COMPILE UNDER GNU/LINUX
=======================

To compile, type:

make

You need to have SDL 2.0 development files installed. The compiled executable
should be generated with the filename 'sdlpal' at the top directory of source
files.

SDLPAL should also be able to compile and run under other UNIX-like systems, 
however it's not tested.


COMPILE UNDER MAC OS X
======================

To compile, open the project Pal.xcodeproj with Xcode, and click Build. You
need to have SDL framework installed at /Library/Frameworks.

The compiled bundle should work as a "universal" binary which works on both
Intel and PowerPC.


REVISED BATTLE SYSTEM
=====================

By default, SDLPAL uses the turn-based battle system which is 100% compatible
to the original game. But SDLPAL also provides a revised battle system which
is more exciting yet somewhat harder than the original game. If you prefer
this version of battle system, please refer to the secion 'CONFIGURE THE GAME'
for how to enable it.


RUNNING THE GAME
================

The data files required for running the game are not included with the source
package due to copyright issues. You must obtain them from the original CD.

To run the game, copy all the files on the original CD to a directory, then
copy the SDLPAL executable to the same directory, and run the executable.

Note that the filenames of data files should be in lower-case under GNU/Linux
(or other UNIX-like operating systems).


CONFIGURE THE GAME
==================

PAL has several variants using different and incompatible resource files. Now
SDLPAL supports several configuration options for supporting such variants.

To set these configuration options, create a file named as 'sdlpal.cfg' (make
sure to use lower-case file name in UNIX-like operating systems) in the game
directory created by the above step. If no configuration file exists, SDLPAL
uses default values that supports the original resources of DOS version.

Please refer to the 'sdlpal.cfg.example' for configuration file format.
