Chrome Dino assets and game logic on blockblast.co are ported from the Chromium project's offline "T-Rex" easter egg. This is an unofficial port; it is not made, endorsed or supported by Google. Source repository: https://chromium.googlesource.com/chromium/src Pinned commit: 1985cb7b30ce45730451a3f23fb23cb5e4b6ceb1 (GitHub mirror: https://github.com/chromium/chromium/tree/1985cb7b30ce45730451a3f23fb23cb5e4b6ceb1) Sprite sheets in this directory, copied unmodified from that commit: offline-sprite-1x.png <- components/neterror/resources/images/default_100_percent/offline/100-offline-sprite.png offline-sprite-2x.png <- components/neterror/resources/images/default_200_percent/offline/200-offline-sprite.png Sound files, transcoded from that commit's files (upstream they are named .mp3 but contain Ogg Vorbis audio, which not every browser can decode). They were decoded and re-encoded as AAC (128 kbps, 44.1 kHz stereo, .m4a) with the same length; the audio was not otherwise edited: sounds/button-press.m4a <- components/neterror/resources/sounds/button-press.mp3 sounds/hit.m4a <- components/neterror/resources/sounds/hit.mp3 sounds/score-reached.m4a <- components/neterror/resources/sounds/score-reached.mp3 Game logic ported and modified from components/neterror/resources/dino_game/*.ts at the same commit (see components/chrome-dino/ in the site source). cover.png is not a Chromium file: it was composed for this site from the unmodified sprite sheet above.
