One of the rumors is when an operator in spain wanted to swap out games on location, he was required to literally destroy the ones being removed. No third party or reselling was allowed. So what was originally a rare 600 game production run turned out to be a 40-50 game survival rate from back then, most of those survivors are now in the hands of private collectors, even fewer of which have any interest in the internet. It's just a rumor I heard - I have no first hand knowledge of any such deals. Who made your spanish Papillon game?
It looks like either Inder or Videodens?
