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)
Header
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
Vertices
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
Microcode
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)
Layout
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.
Structure
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
Unknown2
(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
Header
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.
Structure
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
[AA AA] [BB BB] 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 0000 0001 005B5360 0006D1E4 0002 00858740 0003 009D8CB0 000D9268 0005 011291B0 00074A0C 0007 01BD5C80 00076B28
List-index addressing
(geometry blocks only?)
[AA AA] [BB BB] 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.
