Nintendo has been forced to cancel a time attack contest for NES Remix due to an exploit that allowed players to reduce their times.
The contest saw players completing a level based on the original Mario Bros. from 1983, in which players are tasked with controlling two Mario characters at the same time. In a comment the game’s director, Koichi Hayashida revealed that due to an exploit the contest was being canceled.
“In the interest of being as fair as possible, we decided to terminate the event without recognizing the fastest time,” Hayashida wrote. “We sincerely apologize for this matter, particularly because the vast majority of people played fairly.”
The exploit was related to pausing and resuming the game. It appears that there was a short delay between resuming the game and the clock restarting.
