grid_pc file format

[[V] Knobby]

The world streaming code uses a grid file to define the zones and zone swaps that exist. This allows us to avoid searching for files at level load. Here is the format of that file:

int32 version (5)
int32 number of layers (5: always loaded = 0, interior = 1, world = 2, world high lod = 3, mission = 4)

for each layer
 uint16 layer number
 uint16 number of arrays in this layer(each dlc and the main game had an array of zones)
 uint32 number of zones in this array
 uint16 array index(we saved dlc to their own grid file and it would be built at runtime)
 for each cell
  uint16 cell index
  uint16 layer index
  uint8 grid x coord
  uint8 grid y coord
  uint16 num versions(zone swaps)
  for each version
   string for zone name (probably not null terminated with a number of characters at the beginning) (can be "null" if no base version of zone)
   uint16 version? (always 0xFFFF)

"number of zones in this array" seem to be code on 2 bytes, not 4.
The next two bytes is actually the size of the string.

uint16 number of zones in this array
for each zones in the array
uint16 size of string for zone name
string for zone name
uint16 version? (always 0xFFFF)

Nevermind, I was mistaken.
