Animation records

At this place defined animated sequences.

Each record size is 0x10 bytes.

Each record contain frames count information and pointer to sequences.

Structure:

Offset 0x00 0x01 0x02-0x0B 0x0C
Size 1 byte 1 byte ??? bytes 4 bytes
Description ??? Type ??? Frames Count ?????? Pointer to sequences

Sequences is the id`s of tiles blocks. Sequences consists of that records, count = frames count of this sequence.

One record Staructure:

1 byte 1 byte
Block ID ???Type???

Tile Blocks

In tile blocks records storage information about number of tiles, offset`s of block, and other. Many information are unknown.

Knowed structure:

Offset 0x00 0x01 0x04-0x0B 0x0C 0x0E 0x10-0x17 0x18 0x1A 0x1C-0x23 0x24 0x26 0x28 0x2C 0x30 0x34-0x38

Value = [2*]+[4*] ?????? TileSet ID (for camera settings record) Tiles count Pointer to 4 bytes values (for each tile) Pointer to 8 bytes values (for each tile) Var, address in memory to created packet.[For PSX drawning loop]. ??????  

One file can contain more than one field, for separating blocks used TileSet ID. And for each field exists camera settings.

When gane engine drawning block, he reading tiles count, and reads information needed for creating packets for GPU from 4 bytes and 8 bytes values.

4 bytes values:

Offset 0x00-0x0B bits 0x0C-0x15 bits 0x16-0x1f bits
Size 12 bits 10 bits 10 bits
Description Not used, or zero ???? local coordinate Y [for drawning], from block position local coordinate X [for drawning], from block position

8 bytes values:

Offset 0x00-0x08 bits 0x09-0x0E bits 0x0F bit 0x10-0x13 bits 0x14-0x15 bits 0x16-0x17 bits 0x18-0x1F bits 0x20-0x27 bits 0x28-0x3B bits 0x3C bit 0x3D-0x3F bits

Description CLUT ID Y CLUT ID X Page Y Page X TP ABR v u ?????? Packet type (0: 0x7C, 1: 0x7E) ??????

if packet type is 0x7C, then tile is 16x16 sprite, else if type is 0x7E, packet is ???transparent??? 16x16 sprite.

Camera Settings In asm i found hard coded values:

OFX Screen offset X = 0xA00000

OFY Screen offset Y = 0x700000
