In the past year, Nintendo leaks have ramped up, especially where Pokémon is involved. For instance, Gold and Silver prototypes from Nintendo’s Space World 1999 event recently surfaced. Now, the leaks are reaching critical mass. As highlighted by a ResetEra thread and various other sources, massive Nintendo leaks are being published to 4chan. Included in the leaks are the source code to Nintendo 64, GameCube, and Wii, plus assorted unreleased game demos and myriad other items that are still being explored.
The source of these leaks — which were obtained illegally — is still being ascertained. A finger is being pointed at a server hack of BroadOn, a company that developed software and some hardware for Wii, among other Nintendo consoles. There is also some speculation that it may have come from Zammis Clark, otherwise known as Wack0, who hacked Nintendo in 2018 and narrowly avoided prison. Wack0 is the ultimate source of many of the recent Pokémon leaks.
