The Ben Daglish format is a game music format connected in some manner with composer Ben Daglish, who wrote music for a number of computer games. Online information is sketchy; sometimes the name is misspelled as "Benn". It's apparently connected with Amiga computers. It's unclear how it is similar or different from other formats such as Ben Daglish SID (.bds) or Ben Replay (.ben) (is the latter one even connected with Mr. Daglish, or a different Ben?).
