Description
The cartridge memory (512kB) is divided into 64 banks, 8 KB each. This bank occupies 8 KB of address space between $A000 and $BFFF.
The six lowest bits (5:0) of the ADDRESS written to $D500-$D5FF select the bank. Bit 6 is ignored.
Bit 7 disables the cartridge but regardless of, you can always read one page in the $D500-$D5FF range, which is a copy of the $B500-$B5FF of bank. Therefore, you can place a non-deletable code in the range $D500-$D5FF, which will be active regardless of the state of bit 7. This fragment is switched synchronously with the switched bank and can be read by CPU and ANTIC.
