'''Map script arbitrary code execution''' is an [[arbitrary code execution]] method in {{RBY}}, requiring the [[expanded item pack]]. In speedrunning communities, it is also called APJM<ref>[https://pastebin.com/T5gHcAtb blue 151 full roaming items list - Pastebin]</ref>, and can be used as a type of arbitrary code execution or a specified [[unintended ROM code execution]], so is typically not allowed.
 
==Summary==
Item 42 and item 42's quantity control wMapScriptPtr (D36E-F in {{RB}} and D36D-E in {{Yellow}}), with the index number of item 42 being the first byte to a little-endian pointer, and item 42's quantity as the second. This address[[word]] containcontains the current map script (not to be confused with [[glitch meta-map script activation|the meta-map script]] which is not controlled by wMapScriptPtr).
 
This script is run continuously after the menu is closed. The address can be changed to one corresponding to a different item slot, such as Water Stone x211 (Thunderstone x211 in Yellow) to make the script point to item 3 (D322/D321).
