I went to the trouble of tracking down the complete Famicom Athena set and bought a tape player, so I figured I might as well post the whole danged contents of the cassette. The sound quality came out pretty decently. Chiptunes from the past...
Direct audio capture of the tape cassette included with the Famicom version of Athena. Includes two vocal songs (Psycho Soldier and Kizu Darake no Blue Moon) sung by Kaori Shimizu, as well as various music captured from the arcade game.
