Thanks to slots4home, shaggy, knagle & badbaud for their help! Errors are all cleared and it's working great. I appreciate it.
Great, glad you got it working!

Well what did you do to clear the last of the errors? Flashing 3 etc.
The flashing number in the Coins Played window is just saying that the door had been opened, and now it's closed. It remains flashing until the next paid game, much like the bottom candle light. Some SP chips do the flashing Coins Played number thing, others don't. It's generally mentioned in the PSR if the SP chip supports that.
