An earlier, much smaller leak had also occurred in 2018 which contained the Nintendo Space World 1997 demos for Pokémon Gold and Silver. The leaks are believed to have come from companies contracted by Nintendo in the design of these consoles, and/or from individuals previously convicted of intrusion into Nintendo systems.
