Downloading NSP files from unauthorized sources for games you do not own is piracy and harms developers. Furthermore, connecting to Nintendo’s online services while running modified NSPs can result in a permanent console ban.

A journalist from Kotaku eventually obtained an internal email, leaked by a former Nintendo employee. The subject line: “Project Mnemosyne – 2021 deployment confirmed.”

The email described a partnership between Nintendo and Kawashima’s lab to study “digital persistence of identity after biological death.” In other words: could a person’s thinking patterns, habits, and subconscious rhythms be preserved as a software model? dr kawashimas brain training switch nsp update 2021

The 2021 update was the final piece. It contained a lightweight AI—trained on decades of Kawashima’s own brain scans—that would compare a player’s neural fingerprint to a growing database. If a player stopped playing for over a year, the AI would attempt to simulate their future responses. If the player died, the simulation would continue, indistinguishable from the original—at least within the limited scope of a brain training game.

Soon, a fringe group of neurologists and dataminers formed online. They called themselves the Lobe Keepers. Their theory: Dr. Kawashima, now in his 60s, had secretly embedded a long-term experiment into the Switch version of Brain Training. The 2021 update wasn’t a bug fix. It was the activation key.

According to the Lobe Keepers, the game’s daily exercises didn’t just measure reaction time or memory. They recorded micro-tremors in the player’s stylus input—patterns that correlated with unique neural firing rates. Over months of play, the Switch’s internal accelerometer and touchscreen could, in theory, build a “neural fingerprint” for each user. This article is for educational and preservation purposes

The 2021 NSP update added a new background process: every time the console was connected to Wi-Fi, it would sync these fingerprints to a private server in Sendai, Japan—Kawashima’s home city.

But why?

The most significant 2021 addition was a free content update that added a full Sudoku mode. The base game was criticized for having fewer puzzles than previous entries. The 2021 patch added 100+ Sudoku puzzles across Easy, Medium, and Expert difficulties. This was a major driver for users seeking the updated NSP.
