Nintendo World Championships 1990 is a ridiculously rare game used in the competition of the same name, in which players had six minutes to collect 50 coins in Super Mario Bros. and then finish Course 1 of Rad Racer, with any remaining time spent in the A-Type mode of Tetris. After time expired, the player's scores in each game were tallied, with a 10× multiplier for Rad Racer and a 25× multiplier for Tetris.

It is said to be the holy grail of NES collecting, as just 116 cartridges (90 gray, 26 gold) were produced. Strangely, a music track in this game would be re-used for the Famicom game Hello Kitty World.

Unused Music#

A jovial song likely intended for the title screen, which has no music. Nintendo Campus Challenge 1991 uses it for the name registration screen.

Unused Graphics#

Several characters in the game's font go unused.

Debug Features#

At the title screen, holding A and pressing Select on Controller 2 accesses a timer test. When the timer ends, the game will display the score based on how much time has passed. (For example, 6 minutes and 15 seconds is displayed as 61,500)

Holding B instead will skip Super Mario Bros. (resulting in a score of 0 for it on the final tally) and start you on Rad Racer.

These features don't work in Nintendo Campus Challenge 1991, which implemented a name entry menu by pressing Select.
