List of Super NES enhancement chips

The list of Super NES enhancement chips demonstrates Nintendo hardware designers' plan to easily expand the Super Nintendo Entertainment System with special coprocessors. This standardized selection of chips was available to licensed developers, to increase system performance and features for each game cartridge. As increasingly superior chips became available throughout the Super NES's generation, this provided a cheaper and more versatile way of maintaining the system's market lifespan compared to Nintendo's option of using a much more expensive CPU, or an increasingly obsolete stock chipset, in the Super NES itself.

The presence of an enhancement chip is often indicated by 16 additional pins on either side of the original pins, 8 to each side.^[1]
