EMK (Karaoke Format)
EMK files are simply an archive of the NCN format, compressed into one single file.
An EMK file contains the following data:
- EMK Header (extra metadata)
- NCN Lyrics
- NCN Cursor
All EMK files are XOR encrypted with the magic key
AFF24C9CE9EA994, which when decrypted becomes a DEFLATE stream of an archive with 4 chunks containing these files.
Once extracted, it can be played like a normal NCN file, with extra metadata in the headers.
