One of Super Mario 64's oldest mysteries has a new answer: according to a computational analysis published by programmer Mochi64 and reported by Video Games Chronicle, the plaque on the star-shaped statue in the castle courtyard reads “Eternal Star” on the first line and “We Hope So” on the second, not “L is Real 2401”, the reading that became fan legend.

How the analysis was done

The plaque is a gray 32×32 pixel texture with two lines of text only 3 to 5 pixels tall. At that size, upscaling the image would be pure guesswork. So the project worked backwards: it simulated how a mid-1990s artist would have created the texture, setting the text in a period font, shrinking it, blurring it and adjusting brightness, and then compared each candidate, pixel by pixel, against the game's original texture. The smaller the difference, the better the fit.

According to VGC, more than 1.2 million words were tested. The combination “Eternal Star / We Hope So” scored best, while “L is Real 2401” had a much larger mismatch, about twice as large on the first line. The repository's README names Palatino Bold Italic (1990) as the best-fitting font, better than the game's dialog font, and says a control search with modern fonts found nothing comparable. The words “Eternal”, “Star” and “hope” have the strongest support; “so” is the best fit but by a smaller margin.

Why the case is famous

The “L is Real 2401” theory became tied to the idea that Luigi would be playable in Mario 64. There is a real basis for the discussion: comments from Shigeru Miyamoto in 1996 indicate that Luigi was planned as a second playable character and cut late in development, and footage from the 1995 Space World show may show both characters. But that proves nothing about what the plaque says.

Open source and the “plaque challenge”

The code is on GitHub under the MIT license. The README itself states that it does not distribute Nintendo data, textures or fonts, and that anyone who wants to run the project must supply their own ROM and fonts. The repository also includes a “plaque challenge”: the author invites the community to try to beat the score with a different reading, or to hide a secret word to fool the decoder. The README does not say whether AI tools were used, and VGC's article speaks of “computational analysis”.

What we still don't know

  • Confirmation: Nintendo has not commented and, according to VGC, is unlikely to confirm what the message means.
  • Independent review: the result comes from the author and the project's report; other researchers can still test alternative readings with the same code.
  • Meaning: even if the text is right, why the phrase is there remains open.
