In all of the SNES versions of Final Fantasy IV, it is sometimes possible to open the menu while walking between tiles on the world map. If a Tent or Cabin is then used from the menu, it triggers the "sliding glitch." The map's collision will be shifted one tile away from the direction the player was walking. This by itself is cosmetic, however saving and reloading the game will reset the collision to match the graphics. This means the bug can be used to bypass certain map triggers or other impassible areas. This was fixed in the PlayStation version - it is no longer possible to open the menu when moving.
