Many concepts in this program are based on documents from the PAL Research Project, and portions of the code are based on work by Baldur and louyihua.

This program makes extensive use of the following libraries:

• SDL / SDL_mixer

• libmad, libogg & libvorbis, libopus & opusfile

• FLTK, TinySoundFont

• OPL player from Adplug

• OPL emulation cores from DOSBOX, MAME, and Chocolate Doom projects

• Audio resampler from foo_input_adplug

• AVI player from FFmpeg

• Image decoder from stb

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

We recommend purchasing the original game from Steam to obtain the required data files.

Building the Game

SDLPAL currently supports the following platforms:

• Desktop: Windows (Desktop & UWP), GNU/Linux, and macOS.

• Mobile: Android, iOS, and Windows Phone/Mobile.

• Consoles: 3DS, Wii, PSP, and others (some may not be actively maintained).

For build environment inspiration, you can review our CI scripts.

General Build Steps

1. Clone the repository:

    $ git clone https://github.com/sdlpal/sdlpal.git
    $ cd sdlpal

2. Update submodules:

    $ git submodule update --init --recursive

3. Follow platform-specific instructions:

Windows

• Visual Studio: - For Desktop, open win32/sdlpal.sln in Visual Studio 2017 or later.

  • For UWP, open winrt/SDLPal.UWP.sln.

• MinGW:

  • Windows CMD: cd win32 && make -f Makefile.mingw

  • MSYS: cd win32 && make

  • Linux Cross-compile: cd win32 && make HOST=i686-w64-mingw32- (or x86_64 for 64-bit).

GNU/Linux or Unix

Run cd unix && make. Ensure SDL 2.0 development files are installed. The executable sdlpal will be generated in the current directory. By default, it uses FLTK for the launch GUI; to disable this, define PAL_NO_LAUNCH_UI in the Makefile.

macOS

Open Pal.xcodeproj with Xcode and build. Ensure the SDL framework is installed in /Library/Frameworks.

iOS

Install dependencies via CocoaPods, then open ios/SDLPal/SDLPal.xcworkspace in Xcode.

$ cd iOS/SDLPAL
$ pod install

Android

Open the android directory in Android Studio and select Make Project.

• Note: android/app/src/main/java/org/libsdl/app is a symlink. Ensure your Git client handles symbolic links correctly.

• Tip: On Windows, keep the repository path short (e.g., at the drive root) to avoid path length issues.

Running the Game

Resource files are not included. You must copy the original game data files into a directory, place the built SDLPAL executable in that same directory, and then run it.

Important: On case-sensitive filesystems (like Linux/macOS), ensure all game data filenames are in lower-case.

MIDI Support

MIDI support varies by platform. It is officially supported on Windows, Android, iOS, and macOS. GNU/Linux support is preliminary and requires the timidity package. Other platforms do not currently support MIDI.

Configuration

SDLPAL supports various versions of the original game through configuration.

1. GUI: On the first launch, a configuration window will appear. You can access it later via the in-game menu or after a crash. (Currently unavailable on macOS).

2. Manual: Create a sdlpal.cfg file in the game directory. Refer to sdlpal.cfg.example for the format.

Contributing & Issues

• Issues: Report bugs via GitHub Issues in English or Chinese.
