ArcadeShop Q*Bert high score kit no workie. Also, it's different than JROKs...
I installed the Q*Bert high score save kit from ArcadeShop tonight and it doesn't work. When I turn the game on it freaks out with random sounds and odd graphics. If I pull the battery backed RAM out and replace it with the original RAM the game works again.
I was wondering if the method they describe of jumping the diode was incorrect or did I get bad RAM?
The AS kit says to remove diode D2 and replace it with the included jumper. Which, I did.
However, I noticed JROK outlined something quite different and here:

He shows placing a wire on D3 and running it as shown:
What do you think? Is arcade shops method of replacing D2 ok and I got bad RAM? Or should I try JROKs method? Or are they the same end result?
