Nintendo World Championships 1990

Nintendo World Championships is a video game competition that is organized by Nintendo of America. It was first held in 1990, and later competitions took place in 2015 and 2017. The 1990 competition had its finalists play on a special cartridge that had three games in it, Super Mario Bros., Rad Racer, and Tetris. The goal was to get the highest score under a specific time limit that's set by DIP switches on the back of the cartridge. The players had to get 50 coins in Super Mario Bros., complete a lap in Rad Racer, and score as much as possible in level of Tetris before the time runs out.

TegaMech, Gaster, and Zel collaborate for this run to get the maximum score possible in a game of Nintendo World Championships 1990 with the standard competition time limit of 6 minutes and 21 seconds and pull all the stops for all three games, getting over 14.6 million points in the process thanks to exploiting many glitches and bugs in Tetris.
