Here it is: a compilation of Mega Drive/Genesis covers of THE ENTIRE Yume Nikki soundtrack. No songs/sounds left behind (except for "Glitch", I forgot to include it in the video whoops).
I tried to make it as accurate as possible but the MD sound chips are limited and so is my skill (this is my first try at DefleMask and tracker software in general), so there might be tons of inaccuracies. I took some liberties with some tracks, more noticeably the Aztec Monkey Monkey theme; I couldn't figure it out so I just sampled it lol. All songs in this video should play as-is on actual physical hardware.
