Super Mario 64 Plaque Mystery Solved by AI [Confirmed]

Computational analysis has determined that Super Mario 64's infamous castle courtyard plaque does not read 'L is Real 2401,' debunking one of gaming's longest-running mysteries after millions of automated text-matching tests were run against the blurry in-game texture. According to verified reports from VGC, a researcher applied advanced image recognition and pattern-matching algorithms to the low-resolution plaque texture found in the courtyard of Princess Peach's Castle, systematically comparing it against thousands of possible letter and number combinations. The plaque, which has fueled speculation since the game's 1996 launch, became the foundation of the legendary 'L is Real 2401' theory — a supposed hint that Luigi was hidden somewhere in the game. Speedrunners, dataminers, and ROM hackers spent decades searching for Luigi based on this interpretation. The computational study instead found that the texture most closely matches a generic stone pattern with incidental letter-like artifacts, rather than any intentional readable message. Nintendo has never officially commented on the plaque's meaning.
