This auction is for a very rare fighting mat called the Ultimate Kickboxing Fighting Game Simulation System. It was designed to be used for most fighting games on the PS1 and PS2 systems and some examples given on the back of the box include a boxing game, a Smackdown game, a Tekken game and a Street FIghter game. From the pictures it looks like you place hand and feet sensors on yourself and then use them while standing on the mat. I never used this after I bought it some 10 years or so ago so it's still in new condition.
