A (useless) chip which is only used in some version of Bases Loaded ? I don't have the cart but you can see this here : NES-LD-0-EXP283
Note that the chip is in the same weird package as the MMC2, it is called "Expansion IC", and it is on the PRG bus (mainly). I can really have no idea of why it has been made. Also, since "NES-LD" appears on it, this must be game specific, so that chip would apply to no other game.
