Sega 8 bit "mappers" used 16KB slots, so you can use 4KB pages to emulate them. The mapper is solely to bank switch memory and doesn't do any of the support chip fun that more complex NES mappers do, so it's generally simpler. Only thing to note is the first 1KB (ie the interrupt vector table) is fixed on most mappers, which presumably would need a workaround.
