Arcade Classic No. 4: Defender / Joust, one of the most distinctive late Game Boy compilations because it combines two classic Williams arcade games on a single cartridge. What makes the USA version especially interesting is that it belongs to Nintendo’s short-lived Arcade Classic line on Game Boy, giving it a clear series identity rather than being a standalone port. It is also notable for including Super Game Boy borders styled after the original arcade cabinets and for offering a two-player alternating mode on one Game Boy, even though it does not use the Link Cable.
