Track 64 on the Nintendo Korg DS-10. This is a short one (1:42) that starts with just the two synthesizer voices (tuned square waves on synth 1 and detuned saw waves on synth 2) and continues with pretty much all I could muster from the tiny machine (the 2 synths and the 4 drum channels used as synths). So, the tune has a chip tune feel at the beginning but it quickly morphs into something else, you just have to be a tiny bit patient.
Bpm is 78, key is G major.
Looks like youtube is giving iframe code for embedding now, used to be a flash embed object not that long ago. I guess it's because of mobile phones and the likes.
