Mr. Big Britches	358333125d	libFont: ship Noto Sans as the fallback font (#1917 ) * cmake: download Noto Sans at configure time Fetch the hinted Regular, Bold, Italic and Bold Italic of Noto Sans v2.015 and their licence from the Noto project's font distribution (notofonts.github.io) with FetchContent, like the other third-party dependencies. The commit and each file's SHA-256 are pinned in variables. Only these four styles are needed, so they are fetched individually instead of through the release archive (117 MB, every style and build). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * cmake: ship Noto Sans beside the emulator Copy the downloaded fonts to assets/fonts next to kyty_emulator on every build, like the touch cursors and the trophy sound, and install them there with the SIL Open Font License under licenses/noto-sans. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * libFont: fall back to the shipped Noto Sans instead of Tracy's Roboto Fonts stb_truetype cannot read, including every system font set opened with sceFontOpenFontSet, used Roboto from Tracy's source folder, found relative to the source tree or the working directory. Installed builds have neither, so their system fonts drew every character as '?'. Load Noto Sans Regular, Bold, Italic or Bold Italic from assets/fonts next to the emulator instead, and log when a file is missing.
