Little endian makes sense when you consider how the indexed & indirect addressing modes work. Fetch the first byte (address LSB) add the X or Y register while fetching the second byte (address MSB), if there is a carry take an extra cycle handling that (page boundary penalty), then fetch/store from the destination address. ---------------------------------------------------------------------------------------------- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
