Summary 08267: rollingc: Bonus Life DIP
Description Rolling Crash / Moon Base
Picture below shows Unknown DIP is Bonus Life for both games in this rom set.
ON = 3K for Rolling Crash
          1K for Moon Base

OFF = 5K for Rolling Crash
           2K for Moon Base

"Invincibility Cheat" used for picture 3 only, to show Bonus Life added right at 5000 points mark.
 Hard to acheive 5K in Rolling Crash but I am able to do it with the Lives DIP set on 6 after many tries.
