EMK (Karaoke Format)
EMK is a container format for NCN karaoke files. It is used by Extreme Karaoke to archive songs.
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
- MIDI
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.
