these screensavers have sound, can be muted from settings or even better by opening the win 7 volume mixer just after viewing preview you can reduce the music to next to inaudible. These screensavers work best with proper codecs installed (such as k-lite). if theres any problems please let me know in the comments. This one has credits, I'd like to do a creditless version if one ever comes out. This one is a little larger then i wanted to make these anymore however i didnt want to decrease madokas quality as much because shes worth it.
