This reminds me to another thing: In the CRT/CHIP header these two lines  

are redundant information: The cartridge type (and therefore the emulation 

specific to this type) implies the state of these lines anyway. In many  

cartridges they are even dynamic, so the CHIP header can't know their  

state.
