Depends on what you want... if you just want something to read Carts to play them as ROMs on a PC you can of course read them out via parallel port (there are various DIY manuals for cart-readers for other systems, making one for N64 shouldn't be too hard).

The other direction is somewhat harder, 'cause the parallel port itself is too slow to send ROM information real-time to the N64. So the copiers use RAM to emulate a cartridge, that's why they need zip drives or CD-ROMs to load information from (loading the RAM from parallel port is possible also, of course).
