   - From the manual, it says that DSW bit 6 determines the cost of a game :
       * bit 6 = 0 : "25c / game"
       * bit 6 = 1 : "50c / game"
     When you look at the game code, it appears to be some of "Bonus Coinage" :
       * bit 6 = 0 : you get an additional credit each time you insert 1 coin
       * bit 6 = 1 : you get an additional credit each time you insert 2 coins
