'''Notice: Values used to represent data in this doc are:'''
* '''byte: 8 bit unsigned integer'''
* '''ushort: 16 bit unsigned integer'''
* '''uint: 32 bit unsigned integer'''

WLDTEX.TM2 is an archive containing pieces of raw graphics to be drawn on the PSX VRAM.

'''Notice: PSX VRAM is treated as a 1024x512, two bytes per pixel raw image.'''

Each piece of graphics is organized inside a '''GraphicStructure'''.
A '''GraphicStructureList''' is a list of '''GraphicStructure'''.

The WLDTEX.TM2 archive structure can be described like this:
 

===WLDTEX.TM2 "ARCHIVE" FORMAT===
{| border="0" cellspacing="0" cellpadding="5"
|-
| sizeof(GraphicStructureList) '''bytes'''
| GraphicStructureList1
|-
| sizeof(GraphicStructureList) '''bytes'''
| GraphicStructureList2
|-
| .
| .
|-
| .
| .
|-
| .
| .
|-
| sizeof(GraphicStructureList) '''bytes'''
| GraphicStructureListN
|-
|}


Each GraphicStructureList is 2048 (0x800) '''bytes''' in size. So, N=sizeInBytes(WLDTEX.TM2)/0x800.


====GRAPHICSTRUCTURELIST FORMAT====
{| border="0" cellspacing="0" cellpadding="5"
|-
| '''ushort'''
| Number of GraphicStructures (for example K) contained in this list
|-
| '''ushort'''
| Unknown (always 0, maybe Number of GraphicStructures is an uint)
|-
| sizeof(GraphicStructure1) '''bytes'''
| GraphicStructure1
|-
| sizeof(GraphicStructure1) '''bytes'''
| GraphicStructure2
|-
| .
| .
|-
| .
| .
|-
| .
| .
|-
| sizeof(GraphicStructure1) '''bytes'''
| GraphicStructureK
|}
                                                      

====GRAPHICSTRUCTURE FORMAT====
{| border="0" cellspacing="0" cellpadding="5"
|-
| '''ushort'''
| x-axis on the psx vram (x)
|-
| '''ushort'''
| y-axis on the psx vram (y)
|-
| '''ushort'''
| width of the current GraphicStructure's piece of raw graphics (w)
|-
| '''ushort'''
| height of the current GraphicStructure's piece of raw graphics (h)
|-
| w*h*bytesPerPixel '''bytes'''
| current GraphicStructure's piece of raw graphics
|}

'''Notice: Sometime, the last GraphicStructure of each GraphicStructureList has a piece of raw graphics bigger than w*h*bytesPerPixel bytes  (probably to reach the 2048 bytes size). I extracted all graphics ignoring these bytes, it looks like they are not necessary.'''
