Music from the NeoGeo game King of The Monsters, composed by Kazuhiro Nishida (KONNY) and Toshikazu Tanaka under the SNK Sound Team name. This game was developed and published by SNK, and utilizes a Yamaha YM2610 chip capable of 4-channel FM synthesis, 3-channel square wave generation, and 7-channel ADPCM playback.
The "without intro" song variants were not included in this video since they are essentially the same as the normal stage tracks (just, you know... without the intros).
This was played using the development version of Benben v0.7.0, a high-performance open-source music player written in Common Lisp. You can find out more information about Benben here: https://chiselapp.com/user/MistressRemilia/repository/benben/
