System3 for SDL2

This is an SDL2 port of System3 for Win32 by Takeda Toshiya. It supports multiple platforms, including Android and Emscripten.

Building

Linux (Debian, Ubuntu)

$ git submodule update --init
$ sudo apt install g++ cmake libsdl2-dev libsdl2-ttf-dev libsdl2-mixer-dev librtmidi-dev
$ mkdir -p out/debug
$ cd out/debug
$ cmake -DCMAKE_BUILD_TYPE=Debug ../../
$ make
$ sudo make install

MacOS

$ git submodule update --init
$ brew install cmake pkg-config sdl2 sdl2_ttf sdl2_mixer rtmidi
$ mkdir -p out/debug
$ cd out/debug
$ cmake -DCMAKE_BUILD_TYPE=Debug ../../
$ make
$ sudo make install

Windows (MSYS2)

$ git submodule update --init
$ pacman -S make mingw-w64-ucrt-x86_64-gcc mingw-w64-ucrt-x86_64-cmake mingw-w64-ucrt-x86_64-SDL2 mingw-w64-ucrt-x86_64-SDL2_ttf mingw-w64-ucrt-x86_64-rtmidi
$ mkdir -p out/debug
$ cd out/debug
$ cmake -G"MSYS Makefiles" -DCMAKE_BUILD_TYPE=Debug ../../
$ make

Windows (Microsoft Visual Studio)

• Visual Studio 2019 can be used to clone this repository and will automatically clone submodules as well.
  • If you're using an older version of Visual Studio, install Git and clone this repository using the --recurse-submodules option.
• Install CMake. (The CMake integration in Visual Studio does not work.)
• In the CMake GUI, press the "Browse Source..." button and select the root folder of this repository.
• Press the "Browse Build..." button. Create a new folder (e.g., out) under the top-level directory of the repository and select it.
• Press the "Configure" button. Specify the generator for your version of Visual Studio and click "Finish."
• Press the "Generate" button.
• A System3.sln file should be generated in the build folder. Open it with Visual Studio.

Emscripten

$ git submodule update --init
$ mkdir -p out/wasm
$ cd out/wasm
$ emcmake cmake -DCMAKE_BUILD_TYPE=Release ../../
$ make

To use the Emscripten build, check out https://github.com/kichikuou/web and copy the out/wasm/system3.* files into its docs directory.

Android

See android/README.md.

Nintendo Switch

See switch/README.md.

Running

Usage:

system3 [options]

Options

-noantialias

Disables text anti-aliasing.

-fontfile filename

Specifies the font file used for rendering text. Both .ttf and .otf files are supported.

-playlist filename

filename is a text file that lists the audio files to play in lieu of CD audio tracks, one per line. For example:

# This line is ignored
BGM/track02.mp3
BGM/track03.mp3
...

The first line is not used because track 1 on a game CD is usually a data track.

-fm

By default, system3-sdl2 uses MIDI sound if available. This option forces FM tone generator emulation.

-mididevice number

Specifies the MIDI device number to use. If not specified, the first available device is used.

-game game_id

As System1-3 have slight variations depending on the game, system3 uses the fingerprint of the scenario file (ADISK.DAT) to identify the game being played. This option allows you to override this detection, which is useful when running patched games.

Here is a list of available game IDs and their corresponding titles:

Configuration File system3.ini

Every option that can be set via command line flags can also be configured through the system3.ini file located in the game folder. Refer to system3.ini.example for the file format and available options. Options specified on the command line will override those in system3.ini.

Localizing a Game

System3-sdl2 supports localization, whereas the original System1-3 only supported Japanese. If you're interested in translating games, check out Sys0Decompiler.
