Notes

If you use an ID that is not listed, it will remove the local map fog filter. For example if you use a fog filter of 3 in Caves 1, the room will not have the default orange glow. Some rooms require a 0x1000 (4096 in decimal) mask on the ID. However on rooms that do not require this applying the mask may crash the game. It is recommended that you first test without the mask and add only if the fog filter does not appear.
