Text boxes in the game begin with a special command, detailed as such: |
|||
*'''00''': Normal text. Text characters (found on [[The Big HEX List]]) follow. If an 0x00 byte appears in this region, an [[error code]] will appear and text following it will not be printed. Some characters are control characters which will automatically print a string, line break, new page, etc. |
|||
*'''08''': Runs code following the 08 byte (can be used for arbitrary code execution) |
|||
*'''F5''': Loads a vending machine |
|||
*'''F6''': Loads Cable Club reception lady text |
|||
*'''F7''': Game Corner Pokémon prize menu. The prizes are determined by the text box's index number, stored at FF8C. Some glitch Game Corner prizes also cause buffer overflows. See [[PrizeDex]] for more information. |
|||
*'''F9''': Normal PC |
|||
*'''FC''': PC for items only |
|||
*'''FD''': PC for Pokémon storage only (unused, featuring "Switch on!" text) |

| Bulbapedia also has an article about Custom text boxes. |
Using text pointers sourced in RAM, the player can use arbitrary code execution to write and show custom text boxes.
In Generation I
There are many means of displaying custom text boxes in the game, including:
- Text pointer manipulation
- Glitch sign manipulation (the basis of Pikachu off-screen glitch arbitrary code execution)
- Text box ID matching (e.g. Sea Route 21 0x44 text box glitch (English Yellow))
- Custom Pokédex entries
Specific details on how to bring up the text box pointer are detailed in the articles above. The formatting section below concerns how to define them.
