Room IDs
From Castlevania: Symphony of the Night Wiki
Here is a diagram showing the ID numbers for each room in each zone of the game. It has been shared on discord and lost its original credit; hopefully someone can come along and claim responsibility for it as it is quite helpful!
To find the ID for a room, set an emulator breakpoint on InitRoomEntities (for the appropriate overlay). Then, walk into the room of interest, and see what the `$a0` register is set to. This will be the ID of the room you're entering.
