Found it from Korean BBS. Creator is KwaK101. Cover for OPL2(YM3812) FM sound and recorded for Nuked OPL3.
Ending theme from Usas (ウシャス). Also used for demo mode BGM in Hexa, a Korean arcade game, without license.
Originally it's .IMS file (IMplay Song data, Korean karaoke for OPL2) so I converted to .VGM for listening in modern PC.
