I currently have two Green boards..

One is BBH Call of the wild

Other is BBH Shooters challenge.

Both boards work ok as is, however if I swap U53 security Roms, the Call of the wild will not work in the board that was Shooters challenge.

Is there something I'm missing? Both have Eagle 2.09
 
Um yea, your missing the fact that each board is locked to a particular game by the Code on U61. So in order to make SC a COTW you need to also swap out the U61 chip, and vice versa.
Also there are 2 versions of COTW one uses only half the memory while the other uses all 8 chips.

IT did this so you couldn't swap games easily between boards.
 
Thanks Darren for the quick reply.

I figured it was something like that.

I have a COTW board that either the sign is dead, or the interface on the board for the sign is not working.

I was going to try and swap boards.

I'll live without the sign..
