===Pokémon News Machine buffer overflow===

''Reason why excluded: The glitch may be elaborate; so it is excluded for now until a comprehensive technique to trigger it (and explanation) is found and shown via video.''

[https://forums.glitchcity.info/index.php?topic=7509.msg206449#msg206449 As documented by Háčky], by using [[arbitrary code execution]] in Japanese Crystal, players can theoretically create custom Pokémon News Machine messages. If true; a malformed one could potentially lead to memory corruption and/or arbitrary code execution.

"Metadata

The metadata file is an unstructured hodgepodge of variable-length fields, the boundaries of which can only be determined by parsing each field in its own unique way. In typical Game Freak style, the game makes no effort to validate the data received from the server or protect against buffer overflows. A malformed metadata file can certainly crash the game and corrupt the save file (I’ve done it more than once), and could probably execute arbitrary code."
