Chromium B.S.U. — licença ========================= O Chromium B.S.U. foi criado por Mark B. Allan (2000) e é mantido pelo projeto chromium-bsu (Paul Wise e outros; o AUTHORS do jogo está abaixo). O código e os gráficos são distribuídos sob a Clarified Artistic License (o COPYING do jogo, abaixo). Os efeitos sonoros e as duas músicas são de Brian Redfern (2008), que os doou ao projeto sob a licença MIT/Expat (data/wav/license.txt, abaixo). O que este site serve: o Chromium B.S.U. 0.9.16.1 (a versão mais recente, de 6 de setembro de 2016), compilado do tarball de fontes publicado pelo projeto no SourceForge (chromium-bsu-0.9.16.1.tar.gz) para WebAssembly com o Emscripten 6.0.10: um chromium-bsu.js, um chromium-bsu.wasm e o chromium-bsu.data, com as imagens de data/png e os sons de data/wav do jogo sem mudanças e a fonte abaixo (com uma exceção, o ícone dos power-ups de escudo, explicada abaixo), mais a página play.html que os hospeda. Ficam de fora da build servida os arquivos MIDI de onde as músicas foram feitas, a imagem chrome.jpg (que o jogo não usa), a documentação e as traduções. As opções e os recordes ficam no IndexedDB do navegador. Fonte: o jogo não traz uma fonte (procura a Gothic Uralic instalada no sistema). Esta build usa a Chakra Petch Bold (Cadson Demak e The Chakra Petch Project Authors, SIL Open Font License 1.1, texto abaixo), sem mudanças, do repositório google/fonts. Entram também no binário: o SDL2 2.32.10, o SDL2_image 2.6.0 e o SDL2_mixer 2.8.0 (licença zlib); a libpng 1.6.58 (licença da libpng); a zlib 1.3.2 (licença zlib); o stb_truetype 1.26 de Sean Barrett (domínio público ou MIT); e a biblioteca C e o runtime em JavaScript do Emscripten (MIT / University of Illinois NCSA; musl, MIT; compiler-rt, Apache License 2.0 com a exceção do LLVM). As licenças estão abaixo. Esta é uma versão modificada, "non-standard", do Chromium B.S.U. (Clarified Artistic License, itens 3 e 4). Cada arquivo mudado traz um aviso dizendo como e quando foi mudado, e as mudanças estão livremente disponíveis no código-fonte hospedado junto do jogo (item 3a). A versão padrão está em https://sourceforge.net/projects/chromium-bsu/. As mudanças só valem na build para o navegador: - chromium-bsu-fredygames.patch: - toda imagem é convertida para RGBA antes de ir para a placa de vídeo (os PNG em tons de cinza iam como luminância); - trocar o tamanho da tela redimensiona o canvas, em vez de abrir outra janela, e a tela cheia fica com o botão da página (o navegador só entra em tela cheia de dentro de um evento de entrada); - a nave segue o movimento relativo do mouse travado pelo navegador (pointer lock), porque uma página não move o ponteiro do mouse, e a tecla Q não fecha mais o jogo (o menu ainda tem quit); - o tamanho padrão da tela é 1024x768, os recordes são assinados "player" (o navegador não tem nome de usuário), e fredygames_save(), que a página chama quando a aba é escondida ou fechada, grava as opções (o jogo só as grava ao sair). - data/png/powerUpShield.png, o ícone dos power-ups de escudo, reparo e super escudo, trocado em 23 de outubro de 2026: o original desenha o Tux, o pinguim do Linux, que o site deixa de fora. No lugar dele vai um escudo desenhado pelo FredyGames com o script make-shield-icon.py, no mesmo formato; o próprio PNG traz o aviso da troca, repetido no início do patch. O tarball hospedado vem sem o ícone original. - arquivos novos, escritos para esta build e distribuídos sob a mesma licença do jogo: - cbgl.c e cbgl.h: a parte do OpenGL 1.x que o jogo usa, sobre WebGL; - ftgl.h e ftgl-stb.cpp: a parte da API do FTGL que o jogo usa, sobre o stb_truetype; - chromium-bsu-config.h: a configuração da build, no lugar da que o script configure gera; - powerUpShield.png e make-shield-icon.py: o ícone novo e o script que o desenha. Código-fonte, hospedado junto do jogo: chromium-bsu-0.9.16.1-pruned.tar.gz (o arquivo publicado pelo projeto, sem o data/png/powerUpShield.png original), chromium-bsu-fredygames.patch, cbgl.c, cbgl.h, ftgl.h, ftgl-stb.cpp, chromium-bsu-config.h, powerUpShield.png, make-shield-icon.py, build-chromium-bsu.sh (o script que gera a build servida, byte a byte, a partir desses arquivos com o Emscripten 6.0.10), stb_truetype.h, ChakraPetch-Bold.ttf e o OFL-ChakraPetch.txt. O FredyGames não tem relação com o projeto chromium-bsu nem com os autores do jogo e não é endossado por eles.

Definitions: "Package" refers to the collection of files distributed by the Copyright Holder, and derivatives of that collection of files created through textual modification. "Standard Version" refers to such a Package if it has not been modified, or has been modified in accordance with the wishes of the Copyright Holder as specified below. "Copyright Holder" is whoever is named in the copyright or copyrights for the package. "You" is you, if you're thinking about copying or distributing this Package. "Distribution fee" is a fee you charge for providing a copy of this Package to another party. "Freely Available" means that no fee is charged for the right to use the item, though there may be fees involved in handling the item. It also means that recipients of the item may redistribute it under the same conditions they received it. 1. You may make and give away verbatim copies of the source form of the Standard Version of this Package without restriction, provided that you duplicate all of the original copyright notices and associated disclaimers. 2. You may apply bug fixes, portability fixes and other modifications derived from the Public Domain, or those made Freely Available, or from the Copyright Holder. A Package modified in such a way shall still be considered the Standard Version. 3. You may otherwise modify your copy of this Package in any way, provided that you insert a prominent notice in each changed file stating how and when you changed that file, and provided that you do at least ONE of the following: a) place your modifications in the Public Domain or otherwise make them Freely Available, such as by posting said modifications to Usenet or an equivalent medium, or placing the modifications on a major network archive site allowing unrestricted access to them, or by allowing the Copyright Holder to include your modifications in the Standard Version of the Package. b) use the modified Package only within your corporation or organization. c) rename any non-standard executables so the names do not conflict with standard executables, which must also be provided, and provide a separate manual page for each non-standard executable that clearly documents how it differs from the Standard Version. d) make other distribution arrangements with the Copyright Holder. e) permit and encourge anyone who receives a copy of the modified Package permission to make your modifications Freely Available in some specific way. 4. You may distribute the programs of this Package in object code or executable form, provided that you do at least ONE of the following: a) distribute a Standard Version of the executables and library files, together with instructions (in the manual page or equivalent) on where to get the Standard Version. b) accompany the distribution with the machine-readable source of the Package with your modifications. c) give non-standard executables non-standard names, and clearly document the differences in manual pages (or equivalent), together with instructions on where to get the Standard Version. d) make other distribution arrangements with the Copyright Holder. e) offer the machine-readable source of the Package, with your modifications, by mail order. 5. You may charge a distribution fee for any distribution of this Package. If you offer support for this Package, you may charge any fee you choose for that support. You may not charge a license fee for the right to use this Package itself. You may distribute this Package in aggregate with other (possibly commercial and possibly nonfree) programs as part of a larger (possibly commercial and possibly nonfree) software distribution, and charge license fees for other parts of that software distribution, provided that you do not advertise this Package as a product of your own. If the Package includes an interpreter, You may embed this Package's interpreter within an executable of yours (by linking); this shall be construed as a mere form of aggregation, provided that the complete Standard Version of the interpreter is so embedded. 6. The scripts and library files supplied as input to or produced as output from the programs of this Package do not automatically fall under the copyright of this Package, but belong to whoever generated them, and may be sold commercially, and may be aggregated with this Package. If such scripts or library files are aggregated with this Package via the so-called "undump" or "unexec" methods of producing a binary executable image, then distribution of such an image shall neither be construed as a distribution of this Package nor shall it fall under the restrictions of Paragraphs 3 and 4, provided that you do not represent such an executable image as a Standard Version of this Package. 7. C subroutines (or comparably compiled subroutines in other languages) supplied by you and linked into this Package in order to emulate subroutines and variables of the language defined by this Package shall not be considered part of this Package, but are the equivalent of input as in Paragraph 6, provided these subroutines do not change the language in any way that would cause it to fail the regression tests for the language. 8. Aggregation of the Standard Version of the Package with a commercial distribution is always permitted provided that the use of this Package is embedded; that is, when no overt attempt is made to make this Package's interfaces visible to the end user of the commercial distribution. Such use shall not be construed as a distribution of this Package. 9. The name of the Copyright Holder may not be used to endorse or promote products derived from this software without specific prior written permission. 10. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.

This license is copied below, and is also available with a FAQ at: http://scripts.sil.org/OFL ----------------------------------------------------------- SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007 ----------------------------------------------------------- PREAMBLE The goals of the Open Font License (OFL) are to stimulate worldwide development of collaborative font projects, to support the font creation efforts of academic and linguistic communities, and to provide a free and open framework in which fonts may be shared and improved in partnership with others. The OFL allows the licensed fonts to be used, studied, modified and redistributed freely as long as they are not sold by themselves. The fonts, including any derivative works, can be bundled, embedded, redistributed and/or sold with any software provided that any reserved names are not used by derivative works. The fonts and derivatives, however, cannot be released under any other type of license. The requirement for fonts to remain under this license does not apply to any document created using the fonts or their derivatives. DEFINITIONS "Font Software" refers to the set of files released by the Copyright Holder(s) under this license and clearly marked as such. This may include source files, build scripts and documentation. "Reserved Font Name" refers to any names specified as such after the copyright statement(s). "Original Version" refers to the collection of Font Software components as distributed by the Copyright Holder(s). "Modified Version" refers to any derivative made by adding to, deleting, or substituting -- in part or in whole -- any of the components of the Original Version, by changing formats or by porting the Font Software to a new environment. "Author" refers to any designer, engineer, programmer, technical writer or other person who contributed to the Font Software.
