# Exporta o Ball2Box (Simon Dalvai; codigo AGPL-3.0-or-later, arte propria CC BY-SA 4.0, musica CC BY 4.0, sons e
# icones CC0, fonte Manrope SIL OFL; codeberg.org/dulvui/ball2box, commit cb98f96, o mesmo commit do espelho
# antigo github.com/dulvui/ball2box, ja arquivado) para a web com o Godot 3.5.3 oficial (o projeto e do Godot 3.x
# e o autor tem exemplo de export HTML5): renderer GLES2 do proprio projeto, modelo webassembly_release (sem
# threads: nao precisa de SharedArrayBuffer nem de COOP/COEP), sem PWA. O projeto fica na pasta game/ do repositorio;
# o preset de exportacao e nosso. Por ser AGPL, o fonte exato vai junto (o repositorio inteiro, ja com as mudancas),
# e as mudancas do projeto (todas em ball2box/patch.py, publicado) sao a retirada de botoes e links para sites
# externos (GitHub, site, doacao, lojas, Mastodon, YouTube), mais um aviso de modificacao na tela de informacoes (cujo botao, escondido pelo autor, passa a aparecer) e o CSV de traducoes sem reimportar (para o export ser reprodutivel).
#
#   src/FredGames.Bundler/Builds/build-ball2box.sh
#
# O editor (macOS universal) e os modelos de exportacao vem do release 3.5.3-stable do GitHub, conferidos pelo
# SHA-256 (os mesmos arquivos do SHA512-SUMS.txt do release) e ficam em artifacts/tools/godot-3.5.3 (instalados
# sob lockf; outros scripts compartilham a pasta). O editor roda com HOME dentro da pasta de saida
# (configuracao e modelo isolados).
#
# Saida: artifacts/build/ball2box-cb98f96/{web/,ball2box-cb98f96.tar.gz}, que o bundle.yaml do jogo confere pelo
# SHA-256. O tar.gz e o fonte do jogo inteiro (AGPL-3.0, com o fonte exato servido e as mudancas de patch.py ja feitas) e sai igual a cada execucao.

This is Ball2Box (https://codeberg.org/dulvui/ball2box, commit cb98f9647726a21e59223ce315326847366eb2fc), modified
for FredyGames on 2026-10-29 (AGPL-3.0-or-later, section 5a). The changes are the ones in ball2box-patch.py, published
next to this archive: the buttons and links that opened external sites (the author's website and GitHub page,
donation page, app stores, Mastodon, a YouTube video) were removed, the two shop balls that were unlocked by opening
those pages are free, the information button (credits and licences), hidden in the original, is shown and its screen says the game
was modified, and the translations are loaded from the .translation files in the repository instead of being re-imported from the CSV (so that the
export is reproducible). Nothing else was changed.
