Hi, I am fairly new to arcades and I recently picked up this Rockman the power battle board from an old friend who has had it in storage for 15 years. He doesn’t even know if it works because he doesn’t have a cabinet and only the B board is there. I was pretty lucky to get this game because I know they are pretty rare. I know a little bit about CPS1 and CPS2 games but I don’t know a lot. How do I know if this board has been tampered with in any way? I like collecting authentic games and have been trying to build an authentic collection of the MegaMan arcade series for about a year and a half. Is this game original, or is it a conversion? I’ve looked at many other CPS2 boards and they all look a little different. Thanks for any help you can give me! Here are some pictures of the game.
