Text pointer manipulation

From Glitch City Wiki

This article is a summary page for different variations of glitches, etc. when talked about as a whole.

Text pointer manipulation refers to glitches in which a map's 'text pointer list pointer' with stored at D36C in Red/Blue or D36B in Yellow is changed by modifying Item 40 and its quantity in the expanded items pack. The text pointer list pointer controls a list of texts for that map.

It may refer to:

Text pointer item ball manipulation — A trick to force Pokémon or Trainer battles from item balls, documented by MrWint.
Text pointer manipulation mart buffer overflow glitch — A trick to bring up a Poké Mart with data from a specific source and possibly cause a buffer overflow with corruption to $CF4B from a location chosen by the player.
Text move abuse — A trick to copy data (other than control character bytes) to another location in RAM using unused text command 03 (arbitrary RAM modification).
Arbitrary code execution — Possible when the text pointer list pointer contains an accessible pointer which would point to a location in RAM that is therefore manipulable.
