pub fn import_bk2(
header: &str,
input_log: &str,
rom_sha256: [u8; 32],
) -> Result<(Movie, Bk2Meta), Bk2Error>Expand description
Parse the Header.txt + Input Log.txt text of a .bk2 into a Movie
plus the leftover header Bk2Meta.
rom_sha256 is the SHA-256 of the ROM the caller intends to replay against.
.bk2 carries only a SHA-1 (SHA1 header), so the authoritative SHA-256
identity must come from the loaded ROM; it is stored verbatim on the returned
Movie and is not validated here.
The returned Movie always has StartPoint::PowerOn — .bk2 movies
start from power-on unless a StartsFromSavestate/StartsFromSaveRam flag is
set, and such cross-emulator save blobs are not portable, so they are
rejected. This reuses the canonical movie-import power-on alignment the
.fm2 path established (a deterministic zeroed-RAM cold boot via
Movie::seek_to_start), so imports never desync.
§Errors
Returns Bk2Error for a non-NES platform, an unparseable integer header, a
missing LogKey:, an unsupported save-anchored start, or a malformed
input-log line. Never panics on malformed input.
