SDLPAL

SDLPAL

SDLPAL is an SDL-based open-source cross-platform reimplementation of the classic Chinese RPG game Xiān jiàn Qí Xiá Zhuàn (Chinese: 仙剑奇侠传/仙劍奇俠傳) (also known as Chinese Paladin or Legend of Sword and Fairy, or PAL for short).

Many of the ideas of this program are based on documents from PAL Research Project. Portions of the code are based on the work done by Baldur and louyihua, and the resampler code is based on the code in Kode54's foo_input_adplug project.

This program made extensive use of the following libraries:

• SDL
• SDL_mixer
• Adplug
• libmad
• libogg & libvorbis
• FLTK
• DOSBOX project and MAME project for codes of some the OPL simulation cores

Please see AUTHORS.txt for additional authors.

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

Building the game

The steps for building SDLPAL varies in different platforms. Currently, SDLPAL supports most desktop platforms including Windows (including Windows Store), Linux and macOS, as well as most popular mobile platforms including Android, iOS and Windows Phone. It is also ported to several home console platforms.

Windows

Visual Studio

To build SDLPAL as a Windows desktop app, you can use Microsoft Visual Studio 2015 or Microsoft Visual Studio 2017 (the support of Visual Studio 2013 is deprecated now and will be removed in future) to open the solution file sdlpal.sln under the win32 directory. As a dependency, you need to have SDL 2.0 development or source files installed at the SDL2 directory under the source tree.

To build SDLPAL as a Universal Windows Platform app, you can use Microsoft Visual Studio 2015 or Microsoft Visual Studio 2017 to open the solution file SDLPal.UWP.sln under the winrt directory. As a dependency, you need to have SDL 2.0 source files installed at the SDL2 directory under the source tree.

There are also solution files for building traditional Windows (phone) store app under the winrt directory, but they are deprecated and will be removed in future.

MinGW

To build SDLPAL as a Windows desktop app, you can also use MinGW. Steps for building under MinGW varies depends on the compiling environment you have:

• If you need to compile SDLPAL under Windows shell environment, please go to the root of the source code tree and type:

  $ cd win32
  $ make -f Makefile.mingw
  

• If you need to compile SDLPAL under msys shell environment, please go to the root of the source code tree and type:

  $ cd win32
  $ make
  

• If you need to cross-compile SDLPAL under Linux shell environment, please go to the root of the source code tree and type:

  $ cd win32
  $ make HOST=i686-w64-mingw32-  # This builds a 32-bit executable. To build a 64-bit executable, replace 'i686' by 'x86_64'.
  

Linux or Unix

To build the game, please go to the root of the source code tree and type:

$ cd unix
$ make

You also need to have SDL 2.0 development files installed in the system. The compiled executable should be generated with the filename sdlpal at the current directory. By default, SDLPAL uses the FLTK library to provide setting GUI at launch. If you do not want to use the library, please define he macro PAL_NO_LAUNCH_UI in the Makefile. SDLPAL should also be able to compile and run under other Unix-like systems, however it's not tested.

macOS (OS X)

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

iOS

To compile, open the project ios/SDLPal/SDLPal.xcodeproj with Xcode, and click Build. You need to have SDL2 source files (not development files) extracted in the SDL2 folder.

Android

To build the game, please go to the root of the source code tree and type:

cd android/jni
ndk-build
cd ..
ant debug

You need to have SDL2 source files (not development files) extracted in the SDL2 folder.

Nintendo 3DS

To build the game, please go to the root of the source code tree and type:

cd 3ds
make
make cia

You need to have DevkitPro ARM and SDL 1.2 for 3DS portlib installed. The compiled executable should be generated with the filename sdlpal at the current directory.

Other platforms

To be written.

Choosing the battle system

By default, SDLPAL builds a "classic" turn-based battle system which is designed to be 100% the same as the original game.

SDLPAL also provides a revised battle system (deprecated and will be removed in future) which is more exciting yet somewhat harder than the original game. If you prefer this battle system, please define the macro ENABLE_REVISIED_BATTLE in Makefile or in common.h and recompile the project.

Running the game

The data files required for running the game are not included with the source package due to copyright issues, so you need to obtain them from a licensed game copy before you can run the game.

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

Note that the filenames of data files should be all in lower-case under systems that use case-sensitive filesystems such as Linux or other Unix-like operating systems.

Configuring the game

PAL has several variants using different and incompatible resource files, and 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 case-sensitive filesystems) in the game directory created by the above step. If no configuration file exists, SDLPAL uses default values that supports the resources from original DOS version.

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

Reporting issues

If you find any issues of SDLPAL, please feel free to report them to the development team through Github's issue tracking system using either English or Chinese.

Contributing to the game

Any original code & documentation contributions are welcomed as long as the contributed code & documentation is licensed under GPL. You can use Github's pull request system to submit your changes to the main repository here. But remember, as a step to keep the quality of code, you should write corresponding unit tests before your changes can be merged. The guidance of writting unit tests can be found here.
