Hi Paul, I would make sure the game chip is seated properly,if so,I would say a bad chip. If it was the cd ,it would say mis-match...cause it read the chip

I'm curious as well, as I know that you are thorough and have probably already verified that the pins perform the same functions in the read state. Scratch Head
Could it be a voltage or ground issue?

One way to find out is to go to the mouser website and look up the
specs of these two chips to see what voltages are applied to their legs.
They're not all alike!

 Scratch Head I really do not know either. I was given flash chips and they read good. However,they would not load. Has to be the speed or voltage  Scratch Head . I just know they would not work,so stayed away from them
