Actor Overlay Table
xxxxxxxx yyyyyyyy aaaaaaaa bbbbbbbb
pppppppp iiiiiiii nnnnnnnn ????cc??
This breaks down into-
x y: Start/End Virtual Rom addresses of the actor file
a b: Start/End Virtual Ram addresses of the actor file
p: Ram address of actor file (00000000 if overlay isn't loaded, or if in ROM)
i: Virtual Ram address of the start of the actor instance initialization variables, located within the file
n: Address of actor filename (Debug ROM only, value is 0 in commercial roms)
c: Number of actor instances of this type currently loaded (ram only)
Note: The record for Link's actor in rom (the first record in the table) only sets the vram address that points to the start of the variable info for Link's actor, and the actor file name pointer if it's the Debug Rom.
