Bleep is a music creation program with piano roll interface by Andrew G. Crowell. It lets you jam out chip music really quickly, and it writes directly into save memory, so your work is saved automatically. This is not the final version.

Thanks to Frederik himself for the news!

At the recently held Datastorm 2013 demoparty, Genesis Project released a short but fine Gameboy classic demo named DMG*P-01. The music could have need a bit more pressure, but is okay overall. Two nice graphics are shown, which should at least convince you to spend time with the YouTube video.

Rez is a unique synthesizer program for the Nintendo Gameboy by nitro2k01. It crudely simulates a resonant filter in a way inspired by the resonance algorithm used by the Casio CZ series phase distortion synthesis. It can both produce sounds meant to emulate this effect, and sounds more reminiscent of a hard sync oscillator. It also produces a graphical pattern on the Gameboy screen.
