The Knight Gundam side story was based on an OVA (4 episodes) and was first published for the Super Famicom. Later on they released two games for the Famicom to which this soundtrack is refering to. They are both RPGs (JP-only). Never came around to play them, though.
I was also interested in this soundtrack for being an old Famicom arrangement. You gotta love these
However, it is a solid soundtrack but not 'over the top'. There is also
another one in the db.
