variables.. int, char, etc. anything the driver relies on that isn't automatically saved should be saved.
static variables which are declared and initialized inside functions shouldn't be used because their value won't be the same at the start on future runs if you load the game / driver twice in a row withuot quitting mame.

the new system uses
memory_set_bank(1, data & 0x0f);
with a memory_configure_bank call at some point earlier to set up the bank size etc.
the new system (afaik) automatically supports state saving for the memory region, the old system didn't.
