Here's the format of the area I'm researching of the .sav file:
All addresses are in decimal, values are in hex.
The area starts at 1372.
It is a list of objects, each having a different size, terminated by 0000 0000. There are 3 types of objects; dynamic, static, and semi-static. The list only covers dynamic and semi static. Some objects can be deleted by simply deleting them! (Despite changing the file size!) It might be possible to add objects by inserting them.
Some of the objects I've documented:
All values are 16 bits unless otherwise specified.
