Technical notes

Unfinished Picross puzzle game, part of the libretro-samples repository. No separate upstream -- written directly for the libretro API.

supports_no_game true (cruzes.c:772), valid_extensions "" (cruzes.c:749). Puzzle grid hardcoded in retro_init (cruzes.c:706-717) via load_challenge. retro_load_game (cruzes.c:728-732) sets pixel format and returns true. No file I/O, no RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY call.

Font data (Carlito-Regular.ttf) compiled in via ttf2c (font10.h, font16.h, font24.h).

No BIOS or firmware files required.

Why no files

Game core with no external file dependencies. All assets compiled in.
