Basically nohow. There is no official support for ROM cartridges larger than 2x32kB.
/plus4encyclopedia/500249 summarizes all the port addresses of original I/O devices and known and "widespread" home-brew expansions. $FDFE is "dedicated to" Solder's ROM Expansion Card. Read upon its operation so that you can create a, for a lack of better description, semi-standard device.
No, I won't search for the relevant documentation instead of you.
