I love stuff like this. The above is a piano rendition of the theme from the NES classic Kid Icarus. Back in those days, video game music experienced a golden age with memorable, iconic tunes coming from CastleVania, The Legend of Zelda, Bubble Bobble, and of course, Super Mario Bros. But the music was always in "blips" and "bloops", which was all the technology at the time could muster. So, I love when someone reverse-engineers one of those classic tunes -- all of those songs must have started on an actual instrument, most likely a piano. playing these songs on an instrument really brings out the beauty of these tunes and makes you realize that there is true art value in the old 8-bit video games.
Below is the original tune on the old Japanese Famicom system.
