Like most NeoGeo Pocket Color titles, Sonic Pocket Adventure even supports the link cable, adding two player modes as long as you've got two systems and two copies of the game. These two modes are excellent one player plays as Sonic, the other Tails the Fox (the one who started the link mode always plays as Sonic). In "Sonic Rush", you'll have to race your opponent from the beginning to the end of a game's level here, you'll see a fuzzy silhouette of the other player, but you cannot interact with him. If he gets off-screen, an arrow points to where he is in relation to where you are. The first person to the end of the level wins. The other mode, "Get the Rings", puts you both on different versions of the same level at the beginning of the game, a random counter tells you how many rings you must get to win the game. You can't see the other person in "Get the Rings", which is handy since you're both working on independent levels and you're not stealing rings from each other.
