SDL_mixer reads loop information from WAV files if you use the Mix_Music interface, but NOT the Mix_Chunk interface. So bgm now uses the Mix_Music interface to get proper looping. There's also some code here for reading bgi files (taken from xsystem35) but it's not actually used. There doesn't seem to be a simple way to set up custom loops with SDL_mixer.
xsystem4
xsystem4 is an implementation of AliceSoft's System 4 game engine for unix-like operating systems.
NOTE: This is a work in progress. Some simple ADV games run more or less okay, but most games are not fully working or have game-breaking bug when run with xsystem4.
Building
First install the dependencies (corresponding Debian package in parentheses):
- chibi-scheme [optional, for debugger]
- bison (bison)
- flex (flex)
- meson (meson)
- libffi (libffi-dev)
- libturbojpeg (libturbojpeg0-dev)
- libwebp (libwebp-dev)
- SDL2 (libsdl2-dev)
- SDL2_mixer (libsdl2-mixer-dev)
- SDL2_ttf (libsdl2-ttf-dev)
- zlib (zlib1g-dev)
Then build the xsystem4 executable with meson,
mkdir build
meson build
ninja -C build
Running
You can run a game by passing the path to its "System40.ini" to the xsystem4 executable.
build/src/xsystem4 /path/to/System40.ini
For now, xsystem4 needs to be run in the top-level project directory (i.e. the directory that contains this README file). This will change in the future.
