The precision of this targeting is paramount, as errors can lead to unintended consequences and game instability.
-
Data Injection and Overwriting
Once a target address is located, the Action Replay device injects new data into that location, overwriting the existing value. This injected data dictates the desired alteration. An example is a code designed to modify the species of a wild Pokémon. The code alters the memory location that holds the Pokémon’s species identifier to a value corresponding to a rare or otherwise unavailable Pokémon. This process alters the in-game encounter, effectively spawning a Pokémon that would not naturally occur in that location.
-
Runtime Modification
Memory alterations occur in real-time, while the game is running. The Action Replay device monitors the game’s execution and injects the code modifications as needed. This differs from patching, which permanently alters the game’s ROM. Real-time alteration allows for dynamic changes to the game state without modifying the underlying game file. However, it also means the modifications are only active while the Action Replay device is connected and enabled.
-
Potential for Instability
Incorrect or poorly designed memory alterations can introduce instability into the game. Writing incorrect data to the wrong memory address can corrupt the game’s data structures, leading to crashes, glitches, or data loss.
