Function export_bk2 

pub fn export_bk2(
    movie: &Movie,
    opts: &Bk2ExportOpts,
) -> Result<Bk2Text, Bk2Error>

Serialize a Movie into the two text members of a .bk2 ZIP.

Emits a Header.txt (MovieVersion, Platform NES, region PAL flag, rerecordCount, optional Author / GameName / SHA1) and an Input Log.txt ([Input], a LogKey: declaration, one |-delimited frame line per frame, [/Input]). The frontend writes both into the archive.

Only StartPoint::PowerOn movies export; a StartPoint::SaveState movie has no portable .bk2 representation.

Errors

Returns Bk2Error::Unsupported if movie is anchored to an embedded save state.
