To get score display, you have to KO 5000 opponents. if you so super sudden death, it wont count as any KOs. so to get good KOs fast, follow these rules. First, go to a normal melee and change the rules to 2.0 damage, Very High amount of KO objects(Warp star, Hammers, Green shells, Red shells, Pokeballs can be good, Bob-ombs, Motion Sensors, Freezies, and any others if im forgetting any). Change SDs to zero,and any small stage(Yoshi's story, Battlefield, Fountain of Dreams, etc.) will work better for getting more KOs. Once you've changed the settings, pick Fox(Falco would work too). When the damage ratio is up to two, Fox's reflector kicks as(s). Falco's reflector sends the opponent up, creating long star KOs, but Fox's send em sideways.Make it as long of a match as you want and make sure there are 3 lvl 1 computers. Then you play a match and score some mega KOs.(getting score display is the only way to find celebi in a pokeball and is the only way to get the diskun trophy because catching celebi is a bonus). Have fun.
