by the way, since this thread is getting all the attention..
can I suggest that the save-type be made as a poll option, that can only be modified by registered users who will be tracked for their choices? i.e. A person chooses eeprom 64k, then his name will go under the dropdown list for that option etc. Or assign a universal section for it in the compat listings, independent of card type
also, the compatibility chart is a little unwieldy at the moment....the buttons for the different carts are so small and packed so close together, once you click the wrong button you will get a big mess. Why not have the different carts under a single dropdown list? (even better, have checkbox options for different users that only want to see the charts for one or two brands of cards
