Bust a Groove 2 Codes, Unlockables and Secrets (PSX)

Bust-a-Groove 2 is a music/fighting game released in 1999 for the Sony PlayStation. The game, sequel to Bust A Groove, combines dance-moves with special abilities designed to damage the opponent. It was originally released in Japan as Bust A Move 2: Dance Tengoku Mix, and was never released in Europe. The initial characters of Heat, Hiro, Kelly, Kitty-N, Shorty and Strike were retained from the original Bust a Groove. Bust A Groove 2 removed several of the original game's characters (Pinky, Hamm, Frida, and Gas-O). These were replaced by several new characters: Comet, Bi-O, and Tsutomu. Some new hidden characters were also introduced into the game, and could be unlocked after completing certain tasks.

Pander (also a new addition to the cast) and Robo-z Gold are the only hidden characters that have a unique dance style, other hidden characters merely mimicked others dance moves. If players were able to have a smooth complete dance with no mistakes and no misses and a high score over a certain amount depending on the level, they would then complete a special solo dance show known as Fever Time at the end of the match. Usually a fever time would be completed after the level that's been danced in has been completely intensified. (Wikipedia)
