No special peripherals. It just uses your bog standard fighting game controls. Stick, punch/kick/block. It would plug into any standard Naomi cabinet.
It maybe was just overshadowed by the massive fighting games of the time like Dead or Alive and Soul Caliber.
Also, that link you shared brought me to scans of an old Japanese gaming magazine issues which has FULL move lists for all the characters! Exactly what I was looking for! Amazing, Thank you so much!
