yesyesyes.... from todays viewpoint, 100% right..... but back in time,
the one reason for making a cart-game was copy-protection... and
nothing is easier to crack than a cartridge thats already using its
own clean rom-filesystem :o)

oh and the bankswitching usually wasn't "simple" either :=P it wouldnt
have taken over 15years for certain games to be cracked (made a
disc-version of) if it had been all that easy :o)
