International Superstar Soccer '99

Start by choosing a game mode from the main menu - Exhibition lets you play a single match, while Tournament leads you through a cup competition. You pick your team and the opposing side, then hit the pitch. The core loop is controlling your players to dribble, pass, and shoot while defending against the AI. Matches last a few minutes, so you can jump in and out quickly. The controls are responsive: use the D-pad to move, X to pass or shoot, and S to sprint or tackle. Pay attention to the power gauge when shooting - a fuller bar means a harder kick, but don't overcharge or you'll lose accuracy. If you're playing against a friend, you can connect two Game Boy Colors via link cable for head-to-head matches.
