I changed my l-4 rom to an l-8 rom (same as l-7 but with the multiplayer bug fixed), and i found that the small wheel no longer lands on extra ball or light extra ball. I am using the default 10% chance for extra ball. It definately hit extra ball when i was using l-4. Has anyone else experienced this? Also i found that once i hit 8 billion points the big wheel stops landing on the billion option. Is this by design to keep the score from flipping at 10 billion?
