GoKawiilHobbyist builder BJ unveils Retro Song Bird, a Game Boy cartridge music player
BJ, an independent builder, has created the Retro Song Bird, a device resembling a Game Boy cartridge reader that plays only the music and sound effects stored on Game Boy cartridges rather than the games themselves. It includes a built-in speaker, stereo line-out for external audio equipment, and USB audio streaming of each of the Game Boy's four sound channels, plus the ability to back up ROMs, save data, and export music as WAV files. Only a handful of prototypes exist currently, and the device is not yet for sale.
