Here are the command line options for Karoke Mugen


Displays a help message


Displays current version

Generates a database then quits. This will overwrite the database if it exists.

Tourne en mode demo, utilisé pour la demo disponible depuis le site. Cela désactive l'interface d'admin, empêche les modifications de mot de passe et désactive le player.

Updates the karaoke base in your data folders and triggers a new database generation.


If used with --generate or --validate, this won't throw errors if video files can't be found. A single warning message will be displayed, at least.

If used with --generate or --validate, this will throw errors if .kara files are modified during the generation. (this means one or more metadata are wrong/missing)
