Currently used for research in Starfy 2.

Object Struct

Every object in every map is specified by a 24-byte structure in the ROM:

Object Struct

Offset (bytes)	Size	Description
0x00	2 bytes	x-position of the object
0x02	2 bytes	y-position of the object
0x04	2 bytes	ID of the object.
0x06	2 bytes	Padding to make the struct a multiple of 4 bytes This would change object ID, but the IDs don't go up that high.
0x08	4*4 bytes (16 total)	Behavior parameters (bParams) 0-3. Affects qualities like door destination, treasure value, etc.

Current Method to Manipulate Objects

• Have a completed Starfy 2 save file
• Edit the two bytes at 0x19CC98. This changes the ID of a pearl in Stage 1-1 (subsequent visits)
• (optional) Edit the 16 bytes at 0x19CC9C. This affects the object's behavior parameters, although not much is known at the moment.
• Visit Stage 1-1.

Objects by ID

Objects by index number (Starfy 2). Feel free to contribute (or add your own different work in progress, research notes, etc. in a new heading). These were tested from Lobber's Cave (subsequent visits).
