Main stage table

The table at 000783F4 (800D01A4) controls how each area of a stage is loaded.
For each stage there is an array of area structs. Each list is terminated with an empty struct.

Area structure

  0x00: list_index geo_block_a  List-index of primary Geometry block
  0x04: list_index geo_block_b  List-index of secondary Geometry block
  0x08: u16        skybox_id    Skybox ID
  0x0A: ??
  0x0C: int        music_id     Music ID
  0x10: bank_index level_block  Bank-index of Level settings block 
  0x14: ??
  0x16: ??                      (0009 plays cutscene and crashes)
  0x18: bank_index dust_block   Bank-index of Dust particle settings
  0x1C: bank_index dust_img     Bank-index of Dust particle image
  0x20: char*      area_name    Pointer to dev ASCII level name
  See Resource addressing systems for details on bank_index and list_index.

Geometry block

When a level starts, the entire block is loaded into segment 04.
A table exists at 00076498 with the start and end addresses of each block.
There are multiple lists in ROM that consist of start-end address pairs of the geometry blocks:

Block structure

   1. Header
   2. Vertices
   3. Microcode
   4. G_SETTIMG references
   5. G_VTX references
   6. Entry point groups (Optional)
   7. Layout
   8. Texture scroll settings (Optional)
   9. Unknown2 (Optional)


The header is 32 bytes in size and references assets within the block.
On load, all segptrs in the header are converted to virtual addresses in-place.

   0x00: segptr layout           Points to the Layout section
   0x04: segptr tex_scroll       Points to the Texture scroll section (Optional)
   0x08: int    rendering_mode   Determines how the Layout section is interpreted
   0x0C: segptr img_refs         Points to the G_SETTIMG reference list
   0x10: segptr vtx_refs         Points to the G_VTX reference list
   0x14: int    n_unknown2       Number of entries in the Unknown2 section
   0x18: segptr unknown2         Points the the Unknown2 section (Optional)
   0x1C: int    ??
   b_have_unknown2 checked by code @ 800A9424, 800F6F3C, 800F7110
   0x1C *4|1, passed to 0x800A8358
   unknown2 last 12 bytes of the file? (optional field?)
   rendering_mode is index of the subroutine table at 0x800D4F10, called every frame


16 bytes each, stored buffer-ready:

   0x00: s16 Vx
   0x02: s16 Vy
   0x04: s16 Vz
   0x06: u16 unused
   0x08: s16 U
   0x0A: s16 V
   0x0C: u8  R
   0x0D: u8  G
   0x0E: u8  B
   0x0F: u8  A


All G_SETTIMG addresses for level geometry are stored as bank-indeces.
On load, each bank-index is converted to a virtual address in-place.
[When reading the addresses, if the resource is not in memory, the game loads it?]
All G_VTX addresses are segptrs referencing vertices within the block.

If texture scroll settings are used, there will be jumps to segment 0x0E (Texture scroll settings).

G_SETTIMG reference list

Zero-terminated list of segptrs, all pointing to microcode beginning with G_SETTIMG (0xFD) commands.
[Used to fill in the virtual addresses?]
If there are no images, there will still be a pointer in the header, but the list will just consist of a single 0x00000000.

G_VTX reference list

Zero-terminated list of segptrs, all pointing to microcode beginning with G_VTX (0x01) commands.

Entry point groups

(Optional section for rendering modes 0x18, ....)

Groups display lists together with lists of segptrs to their entry points. Each struct is 8 bytes in size:

   0x00: int    command
   0x04: segptr entry_point

The command field seems to be:

00000000: Start group
   00000001: Continue group
   00000004: End group (entry_point will be NULL)


The interpretation of this section depends on the rendering mode defined in the header.

The following modes are used for the stages and characters:

    0x13: ?
    0x14: List of entry points?
    0x17: List of entry points with matrices
    0x18: List of groups with matrices
    0x1B: ? only on dev level
    0x1C: ? only on dev level

Mode 0x14:

Zero-terminated list of segptrs to microcode entry points.
All elements will be placed without changes to position, rotation, or scaling.

    Mode 0x17:                  |  Mode 0x18:
     0x00: int    command?      |   0x00: int    command?
     0x04: segptr entry_point   |   0x04: segptr group
     0x08: float  x_translation |   0x08: float  x_translation
     0x0C: float  y_translation |   0x0C: float  y_translation
     0x10: float  z_translation |   0x10: float  z_translation
     0x14: float  x_rotation    |   0x14: float  x_rotation
     0x18: float  y_rotation    |   0x18: float  y_rotation
     0x1C: float  z_rotation    |   0x1C: float  z_rotation
     0x20: float  x_scale       |   0x20: float  x_scale
     0x24: float  y_scale       |   0x24: float  y_scale
     0x28: float  z_scale       |   0x28: float  z_scale

It seems if entry_point_list is NULL, the settings are multipliers for following matrices.

	For mode 0x17 and 0x18, command 0x12 seems to terminate the list.
    (Seen command values = 00000000 (always first), 00000001, 00000002, 00000012, 00060000)

Texture scroll settings

(Optional section)

Inserts G_DL branches and dynamic G_SETTILESIZE commands into segment 0x0E for texture scrolling.


   1. Header 0x20 (32) bytes
   2. Big structs 0x78 (120) bytes each
   3. List A?
   4. List B?
   The header and lists are followed by 0x99999999, maybe an end-marker
   1. Header
    0x0C: segptr to segptr list A
    0x10: segptr to segptr list B
   2. Big structs
   3/4. List A/B
    Zero-terminated list of segptrs, all pointing to Big structs


(Optional section)

One or more bank-index pairs? Count is determined by the header's n_unknown2 field.

Level settings block

The level settings block controls the camera, collisions,
Basic structure

   1. Header
   2. Unknown1
   3. Unknown2
   3. Secondary header?
   4. Entity List


   0x00: u32 Offset to unknown 2
   0x04: u32 Offset of secondary header (collisions/camera)
   0x08: u32 Offset of Entity list

When the entity block is loaded, the offsets are converted to virtual addresses in-place.

Entity list

Each entity struct is 0x2C (44) bytes in size and contains information like type, position, and scale:

   0x00: u8 ?
   0x01: u8 ?
   0x02: u8 entity_id
   0x04: u8 ?
   0x05: u8 ?
   0x06: u16 ?
   ....: ?
   0x20: float scale
   0x24: x position

See kirby-entity-ids.txt for a list of entity IDs.
The subroutine at 800FC9C0 ("spawn_entity") is used to spawn individual entities when Kirby is within range.
There is a 4-byte end marker 0x99999999 at the end of the list.

Particle settings block

Determines how dust particles move around in a level.

1. Number of particles
2. Particle offset list
3. Particle settings

Variable-length structures? (The floats seem to control the speed of the particles)

Resource addressing systems

A few different addressing systems are used to reference and load resources from ROM.

Bank-index addressing

   A = Bank number, selects bank ROM address
   B = Index, selects bank offset
   (Index+1 is used to calculate the size of the resource.)

Misc banks
(Level settings, particle images, ...)
The function at 800A9AA8 is used to load the resource and return its RAM address. (800D0184 table of pointers to offset lists?)

   Bank  Address  Offsets
   0000  004F3290 0006CA0C
   0001  007BACA0 0006FA64
   0002  00964660 000712D0
   0003  00BD6DB0 000730C4
   0007  01D28720 00077F30

Image banks
Bank-indeces for images are used for addresses for G_SETTIMG commands in display lists.
The function at 800A8BAC is used to load the resource and return its RAM address.

   Bank Address  Offsets
   0001 005B5360 0006D1E4
   0002 00858740
   0003 009D8CB0 000D9268
   0005 011291B0 00074A0C
   0007 01BD5C80 00076B28

List-index addressing
(geometry blocks only?)

   A = List number, selects the list
   B = Index, selects the ROM start-end address pair from the list

Geometry block list
There are multiple lists of ROM start-end address pairs for geometry blocks.
The function at 800A9864 is used to load the resource and return its RAM address.

"Rough" Notes

shygoo 2017


geometry file

header+0x04 is scrolling texture settings

for each struct in the section, there is a jump to segment 0E in the microcode

target grows by 8 for each eg

0E000000, 0E000008, 0E0000010

Segment 0E structure

 802C97F0: DE010000 802C9828 // G_DL branch 802C9828
 802C97F8: DE010000 802C9838 // G_DL branch 802C9838
 802C9828: F20AC021 001A421D // G_SETTILESIZE <- Coordinates change actively to scroll texture
 802C9830: DF000000 00000000 // G_ENDDL
 802C9838: F20AC021 001A421D // G_SETTILESIZE <- Coordinates change actively to scroll texture
 802C9830: DF000000 00000000 // G_ENDDL
 For each list of segptrs to the scroll setting structs,
 there is a set of branches and g_settilesize instructions

 level 0 has a list of 7 and another list of 14
8036F1B8 scrolling structs
800CE248 geometry block addresses in ram
