The particle overlay table manages the particle effect files (overlays). It defines a particle effect's id, maps the particle's code to a virtual address, and during gameplay is used to find the overlay in ram

Format

xxxxxxxx yyyyyyyy aaaaaaaa bbbbbbbb
rrrrrrrr pppppppp ????????

  • x y: Start/End Virtual Rom addresses of the particle effect's file
  • a b: Start/End Virtual Ram addresses of the particle effect's file
  • r: Ram address of the overlay, when loaded into ram. Set to 0 in Rom
  • p: ?, possibly a pointer to the initialization routine
  • ?: Unknown, set to 0x01000000 in Rom

The actor table manages the actor files (overlays). It defines an actor's number, maps the actor to a virtual address, and during gameplay is used to find the overlay in ram.

Format

xxxxxxxx yyyyyyyy aaaaaaaa bbbbbbbb
rrrrrrrr iiiiiiii nnnnnnnn vvvvcc00

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
r: 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 releases)
v: Allocation Type, affects how overlay is allocated. See below for values
c: Number of actor instances of this type currently loaded (ram only)

Allocation Type Values

00 performs a "low to high" address allocation (high address volatility), unloading the overlay if no instances of that actor exist
01 performs a "high to low" address allocation (low address volatility), reserving a fixed space for all overlays of this type until the scene is destructed. Only one overlay of this type can ever be loaded at once. The pointer to this space is located at Game Play + 0x1C60
02 performs a "high to low" address allocation (low address volatility), keeping the overlay in ram until the scene is destructed

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.

This table defines the top-level states the game can execute in (Map Select, Boot Logo, the playable game itself, etc.), and reserves variable space for each state

Format
