LSDJ, Little Sound Disk Jockey, is a homebrewed cartridge for the Nintendo Game Boy, programmed by Johan Kotlinski (known to the chiptune world as Role Model), that enables the user to sequence and program music on a Game Boy. The LSDJ is primarily used by chiptune artists, however it is also popular with many other musicians for writing songs featuring Game Boy sounds....
