"""Code reads platform entries by the keys the platform YAMLs write.

expand_platform_declared_names skipped archive members through
`fe.get("zippedFile")`, the upstream Batocera spelling. The YAMLs write
`zipped_file`, so a member's md5 was taken for a loose file and its name
counted as declared: 76 Batocera entries added names such as boot0.rom.
