There’s a whole subculture to video games where highly skilled players dive deep into games in search for new ways to break and master them, trying to find gaps in the digital seams that make up game worlds.

One such glitch-hunter, pannenkoek2012, is offering a $1,000 bounty to anyone who can figure out how to replicate a bug he discovered accidentally in the 1996 game Super Mario 64. Somehow, this particular exploit in the game’s code went unnoticed and unexplained for almost 20 years. You can get a thorough explanation of the glitch and the bounty that goes with it in pannenkoek2012’s video, above.

High-level players use glitches to do things like set records for how fast they can finish the game, or to complete other challenges like limiting the number of times Mario can jump during a specific playthrough. It might seem weird, but a new glitch like this is highly valuable to die-hard Mario 64 players and could even help lead to things like new speedrun world records.

So far, no one has claimed the bounty. So if you feel like grabbing a Japanese copy of Mario 64 and pressing Mario’s face against a wall for hours while trying to make him jump weird, there’s still money in it.
