Nintendo World Championships 1990

Nintendo World Championships 1990 is a competition cartridge created for a specific multi-city tournament. The event format strings together three distinct games into a single timed session, with the total available time being adjustable via hardware switches on the cartridge itself.

Scoring is cumulative but uses different multipliers for each segment. The final tally combines the results from Super Mario Bros., where the objective is to gather coins under modified conditions, Rad Racer, which is a timed race, and Tetris, played until the overall clock expires.

The sequence begins with a modified Super Mario Bros. stage focused on coin collection, after which the player immediately transitions to a Rad Racer course. Performance in this racing segment is tracked internally and its result is factored into the running total. All remaining time in the session is then devoted to scoring points in Tetris, which carries the heaviest score multiplier. When time elapses, a final composite score is presented.
