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) FE: Loads a Poké Mart FF: Loads a Pokémon Center
