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

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
