Unlocking Match 31 in Super Smash Bros. Melee (GameCube): Doesn't Exist

There is no Match 31 in Super Smash Bros. Melee.

• Event Match mode has exactly 51 events (1–51).
• Classic/Adventure/All-Star modes have fixed stage counts (11–14 stages).
• No hidden "Match 31" exists in any mode.

What You Might Be Thinking Of

• Event 31: "Mario Bros. Madness" — Fight Mario & Luigi on Mario Bros. stage. Unlock: Clear Event 30.
• Target Test / Home-Run Contest — Character-specific, not numbered matches.
• VS. Mode "Melee" count: Tracks total VS matches played — can reach 31, but not an unlock.

Check Data → Records → Event Match to see your progress. If you're stuck on Event 31, the trick is: grab the Starman when it spawns, kill Luigi first (he's more aggressive), then Mario.
