Scenes

Scenes are loaded into RAM at a fixed location, though the scene table is flexible enough to change this location. A more technical term for these "scenes" is overlay, as they are a memory overlay in implementation.

Default location of the scene tables:

Game	ROM Offset	RAM Address
Mario Party 1	0x000C2874	0x800C1C74
Mario Party 2	0x000C9474
Mario Party 3	0x00096EF4

A scene table entry has the following format:

struct SceneTableEntry {
    u32 rom_start;
    u32 rom_end;
    u32 ram_start;
    u32 code_start; // Same as ram_start
    u32 code_end;
    u32 rodata_start; // Same as code_end
    u32 rodata_end;
    u32 bss_start; // Same as rodata_end
    u32 bss_end;
}
