# Frozen Bubble: license and credits This port is made from **Frozen Bubble 2.2.0** (2008), the last release of the Perl game (http://www.frozen-bubble.org/; the tarball `frozen-bubble-2.2.0.tar.bz2`, `re/frozenbubble/fetch.sh`). ``` Copyright (c) 2000-2008 The Frozen-Bubble Team. This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License version 2, as published by the Free Software Foundation. ``` * **Design and programming:** Guillaume Cottenceau. **Artwork:** Alexis Younes, Amaury Amblard-Ladurantie. **Soundtrack:** Matthias Le Bidan. **Level editor:** Kim and David Joham. **Additional network programming:** Mark Glines. **Bugfixes and improvements:** Dirk Stoecker, Anton Moll. **Helps and bugfixes:** Seth W. Klein, Jonas Petersson. (The original's `AUTHORS`, which also names the translators of its languages.) * The C extension `c_stuff` (the graphical effects): Copyright (c) 2001-2008 Guillaume Cottenceau, GPL version 2. The level editor `FBLE.pm`: Copyright (c) 2002-2003 Kim Joham and David Joham, GPL version 2. The network code `fb_net.pm` and the game server `server/`: Copyright (c) 2004-2008 Guillaume Cottenceau, GPL version 2. * The data (graphics, sounds, music, levels, the demo records) is part of the same package under the same license (the original's `COPYING`; Debian distributes it the same way). It is used unchanged: `assets/fb-data.bin` holds the original's image files byte for byte, the levels, `plasma.raw` and the demo records (decompressed from their `.bz2`), made by `re/frozenbubble/tools/pack.py`; `assets/snd/` holds the sounds and musics as they are. ## This port: GPL-2.0-only The port is a derivative work of Frozen Bubble: the Perl program, its C extension and its level editor translated to TypeScript (`src/fb/`), with an emulation of the parts of SDL 1.2, SDL_image, SDL_mixer, SDL_Pango and SDL_perl the game uses (`src/sdl/`), an XM player for the two-player music (`src/audio/xm.ts`), and glibc's `sin` and `cos` (`src/fb/libm.ts`, `src/fb/sincostab.ts`, translated from the GNU C Library's `sysdeps/ieee754/dbl-64/s_sin.c`, IBM Accurate Mathematical Library, LGPL-2.1 or later, used here under the GPL as the LGPL allows). It is licensed under the **GNU General Public License, version 2 only**, like the original: see `licenses/GPL-2.0.txt` on this site (https://www.gnu.org/licenses/old-licenses/gpl-2.0.html). What the port changed is listed in `README.md`. This program comes with ABSOLUTELY NO WARRANTY. The source code of the port, the tools that build its data and the test oracle are in this site's source archive ("Licenses & source"). ## The font: DejaVu Sans The original draws its text with SDL_Pango in the system's "sans" font, on Linux DejaVu Sans. The port ships DejaVu Sans 2.37 (`assets/fonts/`: DejaVuSans.ttf, DejaVuSans-Bold.ttf, DejaVuSans-Oblique.ttf, unchanged) under its license: ``` Fonts are (c) Bitstream (see below).

AMSFonts (v. 2.2) copyright The PostScript Type 1 implementation of the AMSFonts produced by and previously distributed by Blue Sky Research and Y&Y, Inc. are now freely available for general use. This has been accomplished through the cooperation of a consortium of scientific publishers with Blue Sky Research and Y&Y. Members of this consortium include: Elsevier Science IBM Corporation Society for Industrial and Applied Mathematics (SIAM) Springer-Verlag American Mathematical Society (AMS) In order to assure the authenticity of these fonts, copyright will be held by the American Mathematical Society. This is not meant to restrict in any way the legitimate use of the fonts, such as (but not limited to) electronic distribution of documents containing these fonts, inclusion of these fonts into other public domain or commercial font collections or computer applications, use of the outline data to create derivative fonts and/or faces, etc. However, the AMS does require that the AMS copyright notice be removed from any derivative versions of the fonts which have been altered in any way. In addition, to ensure the fidelity of TeX documents using Computer Modern fonts, Professor Donald Knuth, creator of the Computer Modern faces, has requested that any alterations which yield different font metrics be given a different name. $Id$ ``` ## Favicon The favicon of the game's page (`web/icons/frozenbubble.png`, 48x48, and `web/icons/frozenbubble-180.png`, 180x180; drawn by `web/scripts/icons.py`) is the penguin of the original's pause screen, `gfx/pause_0001.png` (artwork by Alexis Younes and Amaury Amblard-Ladurantie, GPL-2.0-only, above), cropped to head and shoulders and placed on an ice-blue rounded square.
