Additional Information
Notes
Thanks to the Taisei Project team for this free and open-source Touhou Project fan game. The game code is MIT licensed; the soundtrack by Tuck V and the character portraits by afensorm are CC-BY 4.0.
Built from taisei v1.4.6 with the OpenGL ES 3.0 renderer. SDL3 is provided by the sdl3-sdl2-backend libSDL3.so.0 shim, which runs on the device's own SDL2. The shim is built from commit 6057d79 with the same fixes patch as railroadrampage.
The game data ships as data-part*.tar.gz and is extracted on first launch. Saves, settings and replays are stored in taisei/conf/. The shader cache is stored in taisei/cache/; the first launch takes longer while it is built.
