Barrett

A Rise of the Triad source port based on ROTTEXPR focused on QoL for players and developers, expanded compatibility, new features, and better support for modern hardware.

Requirements

Libraries:

SDL2.dll (https://www.libsdl.org/download-2.0.php)

SDL2_mixer.dll (https://www.libsdl.org/projects/SDL_mixer/)

Game Files:

DEMO1_3.DMO
DEMO2_3.DMO
DEMO3_3.DMO
DEMO4_3.DMO
REMOTE1.RTS

And

DARKWAR.RTC
DARKWAR.RTL
DARKWAR.WAD

Or

HUNTBGIN.RTC
HUNTBGIN.RTL
HUNTBGIN.WAD

Place all those files in the same directory as the barrett executable.

Music

Linux users are required to supply their own soundfont, and their distributions FluidR3 is the default fallback. Soundfonts are searched for in userdata/barrett.sf2 in the game's root folder, as well as these locations:

/usr/share/soundfonts/default.sf2

/usr/share/sounds/sf2/default-GM.sf2

/usr/share/sounds/sf2/FluidR3_GM.sf2

For Arch Linux, the soundfont-fluid package provides this fallback. Additionally, in the Ext User Options menu, OPL emulation can be enabled. OPL emulation can be configured through userdata/opl.ini.

Windows users are currently limited to using the default Windows MIDI subsystem, and can not use soundfonts due to the limitations of SDL_mixer.

Building

To build the project, you'll need the SDL2.0 development libraries
(https://www.libsdl.org/download-2.0.php) as well as the SDL_mixer developement
libaries (https://www.libsdl.org/projects/SDL_mixer/, under Binary).

For Linux users, install the respective SDL2 dependencies through your distro's package manager.
Barrett can be compiled with either GCC or Clang. On Windows, use something such as MinGW's GCC.

This project currently uses CMake. You can create a build target and then build with the commands

cmake -Bcmake-build-barrett -DCMAKE_BUILD_TYPE=Release -S.
cmake --build cmake-build-barrett

For CMAKE_BUILD_TYPE, please refer to the CMake docs.
You could alternatively create different build targets for registered, shareware etc.

Please review the CMakeLists.txt file to customize your build options.
