Thanks to Create Digital Music for pointing out this Game Boy sound comparison from Herbert Weixelbaum. It's a detailed comparison with pictures of sound output from almost all Game Boy models, from the original "Classic" to the Nintendo DS. This is a follow-up to his old comparison. LSDJ was used to create the music. There is an mp3 of the music for each model and a discussion of the benefits and disadvantages.
