Glad you figured it out. Sometime have a cup of coffee ( or your favorite
beverage ) and look over the switch matrix in your games manual. They are
all connected together. A broken wire can take out the next switch, a stuck
closed switch can short the matrix and make others erratic. A backwards
diode can trigger other switches. The switch matrix is an amazing thing,
simple, yet the littlest thing can cause you headaches.
Good job on sorting it out. And you learned something very important. When
things act up - what is the last thing you did ? That can save you a lot of
time. LTG
