Supper Mario Broth, the longtime online archivist and curator of extraordinarily specific Mario discoveries, has shared that heart failure and declining eyesight may eventually limit his ability to maintain the project. Broth, who prefers to be known publicly by that name, says he plans to continue publishing Mario facts for as long as he can.
In a public message posted November 8, Broth said a prognosis had given him a two-in-three chance of surviving a year. He also explained that retinopathy—described by Broth as a gradual degradation of eyesight—is among the complications affecting him. That is especially consequential for a project built around looking closely at games, imagery, archival material, and submissions from other fans.
“I am scared I will soon not be able to see Mario again. However, I promise that until that day arrives, I will always be here, posting Mario facts.”
Broth later made the practical stakes of the diagnosis plain: being able to see well is fundamental both to personally researching Mario material and compiling discoveries sent in by others. Still, his stated intention was unambiguous: “only blindness or death” would stop the Mario facts.
Why eyesight is central to this particular kind of game research
“Mario facts” can sound frivolous until one considers the breadth of the work behind them. Supper Mario Broth has operated since at least 2012, accumulating and presenting unusual details from Mario games, comics, television programs, films, advertising, and other related material. The project’s subject is not simply Mario lore in the familiar sense of character biographies and plot timelines. Its focus is often the accidental, obscure, visually strange, technically curious, or forgotten detail that would otherwise disappear into decades of releases and promotional ephemera.
That kind of research depends on attention: inspecting screenshots, revisiting individual scenes, comparing assets, parsing old materials, and evaluating what a game is actually doing rather than what a player merely remembers it doing. It also involves editorial judgment. A finding needs enough context that readers understand whether it is a programmed behavior, an unintended glitch, an unused or incidental detail, a joke in a licensed work, or something outside the main continuity.
Broth’s own description distinguishes two sides of this labor. There is original research, meaning the process of finding and documenting details directly. Then there is compilation: reading discoveries from other people, assessing them, and presenting them in a form the wider community can understand. Vision loss could make both much more difficult, even if fans remain eager to submit leads and preserve information.
Retinopathy, in the general sense used by Broth, refers to damage or disease affecting the retina, the light-sensitive tissue at the back of the eye. The available information does not establish details beyond Broth’s account of his eyesight gradually worsening, and it would be inappropriate to draw medical conclusions beyond what he has shared. What is clear is the direct functional concern: visual work is not incidental to running an image- and game-detail-heavy archive.

A record of Mario’s odd corners
The community knows Supper Mario Broth for turning things that might otherwise be tossed off as trivia into memorable pieces of game history. One well-known example is a Yoshi’s Island glitch that can stop the game for 25 minutes. Another concerns an animation detail in Super Mario Odyssey, where Bowser reacts fearfully when Mario is shirtless. The archive has also circulated stranger lore-adjacent curiosities, including the unsettling, explicitly non-canon idea that 1-UP Mushrooms grow from dead Marios.
Those examples illustrate why labels matter. A glitch is an unintended game behavior, not necessarily a deliberate design choice. “Non-canon” means a detail is not part of the official continuity of the core fictional setting, even if it appears in a related work or has become famous among fans. A visual reaction in a game can be a small programmed flourish rather than a sweeping statement about a character. Supper Mario Broth’s appeal has long rested on this willingness to give small oddities their proper frame: funny, surprising, sometimes haunting, and often far more specific than standard franchise conversation allows.
Mario is one of gaming’s most heavily documented properties, but sheer scale does not automatically produce accessible preservation. Games change across regions and releases. Promotional materials can be transient. Television, comics, and films create their own branches of material. Old quirks are easily remembered inaccurately, while a strange detail visible for only a moment can be missed altogether. The result is an enormous field where a dedicated specialist can still uncover something new to most players.
That work matters because it preserves more than punchlines. It provides a living record of how a giant game franchise has been represented, marketed, localized, animated, and interpreted across different media. It also gives the internet a less polished kind of game history—one that has room for bugs, background gags, awkward designs, bizarre licensed detours, and the unexpectedly human excitement of someone noticing what everyone else passed by.
Support had already kept the archive going once
This is not the first time Broth has described a threat to the project’s future. In 2024, he said financial strain following his mother’s death had put the blog in danger of closing. Fans responded with support that he said would allow the Supper Mario Broth project to continue indefinitely.
That earlier moment is useful context, though it is importantly different from the current situation. Financial pressure can sometimes be relieved by a community’s material support. Health and accessibility challenges are more personal and less predictable. Broth has not presented a concrete new plan, schedule, or succession arrangement; he has said that he hopes to continue for years and will maintain the blog for as long as he can. Readers should not treat that determination as a promise that physical limitations can be overcome through willpower alone.
Instead, the message is both a commitment and a candid acknowledgement of uncertainty. Broth is not announcing a final post or a planned closure. He is saying that his capacity to do the work may change because the work requires abilities his illness may affect. There is a difference between celebrating the resolve in that statement and imposing an expectation that he continue at any cost.
What a fan-built archive can mean
Major franchises often survive through formal institutions: publishers, developers, museums, media companies, and official social channels. But a great deal of the texture around games is maintained by individuals and communities. They identify obscure behavior, save scans, compare versions, contextualize a joke, and make a decades-old observation legible to people who were not there when a game first released.
Supper Mario Broth represents an unusually concentrated version of that work. The project has become a recognizable place for people who want a Mario fact stranger and more exact than the usual “did you know?” format. Its longevity also shows that a niche voice can become meaningful cultural infrastructure without becoming corporate or anonymous.
There is a broader lesson in the attention now directed toward Broth: archives run by individuals have human limits. A blog can look like an endlessly replenishing feed of curiosities, but it is sustained by time, concentration, access, and health. When readers value that work, the best response is not to demand an endless stream of material. It is to recognize the work already done, respect boundaries, and allow the person behind it to set the pace.
The wider Nintendo community has recently been reminded that creative work and relentless output can come with costs; Masahiro Sakurai has also said he continues to work “at full throttle” while not recommending that pace. The circumstances are not the same, but both cases point to an easy truth to overlook when beloved work arrives regularly: enthusiasm from an audience should never become pressure on its creator.
For now, the facts continue
Broth closed his message by saying he hopes, “with all my (failing) heart,” to continue for years. He also offered a direct note of gratitude in the event that he one day stops posting: “thank you very much for reading.”
For Mario fans, that is a sobering update about a creator whose work has made the series feel larger, stranger, and more alive. For the archive itself, it is not yet an ending. Supper Mario Broth remains committed to the task that made the project beloved: finding, preserving, explaining, and sharing the Mario details that most people would never think to look for.
