| === Overworld lag ===
| |
|
| |
| When the phone rings in the overworld, if the player answers it on a specific frame, the game can lag, causing unintended effects, such as NPCs disappearing, and can even lead to arbitrary code execution. This can happen because normally, when either opening the map with Start, entering a building, or triggering a Telefang battle, the game writes temporarily bytes for sprites (including Shigeki and NPCs) from main RAM to SRAM, which are later written back to main RAM when a battle ends or the map is closed. Lag can prevent all of the bytes being written before an interrupt occurs. This glitch can be abused in speedruns, including a tool-assisted speedrun that beats the game in just over 5 minutes.
