I started with the dual ROM design, and put A13 in there in case someone 
wanted to use the design for a single cart game, and did not want A13 to 
be connected.

Then, I modified the design to be the single ROM version, and I think it 
just got left in, with the weak idea that perhaps someone would need to 
have A13 connected for some reason, but most often it would not be needed.
