The big picture: For more than 30 years, Super Mario 64 players have wondered what's written on a plaque on the fountain in the courtyard of Peach's castle. The text, which measures just 32 x 32 pixels, is far too small to decipher with the naked eye. Fans of the game came up with their own interpretations over the years but now, we might have a somewhat definitive answer as to what the text actually says.
The leading theory up to this point is that the text reads, "L is real 2401." This theory gained traction after it was published in an April Fool's Day feature in Nintendo Power magazine in 1998 and without a better answer, it stuck.
Nintendo originally planned to include Luigi in Super Mario 64 but he was cut from the game near the end of development. Fans held onto hope that he somehow might be a secret character and thus, the L is real 2401 legend stuck.
Armed with modern AI tools, enthusiast supermochi64 decided to take a deeper look at the plaque. Using Claude (Opus 5.5), he tackled the problem exactly like a texture artist would have made the plaque in the mid-90s. Then, a GPU was used to test millions of fonts, settings, and words and gave them a score.
The best guess using this technique is, "Eternal star / We hope so."
AI determined the text was written in Palatino Bold Italic, from Adobe's original 1990 version that shipped with Macs of the era. When "L is real" was plugged into the AI, it scored twice as badly as "Eternal star" in terms of being a likely match.
The truth is, we may never know for certain what was originally written on the plaque. The most definitive answer would be to track down the artist responsible for the graphic, but that could be like finding a needle in a haystack considering it was made over three decades ago. What's more, Nintendo often prefers to let little mysteries like these persist.
