Range data

Gives the limits of the camera when moving.

typedef struct {
   qint16 top;
   qint16 bottom;
   qint16 right;
   qint16 left;
} Range;

Each range corresponds to a background layer.

Always (0, 224, 320, 0) twice. The first range change the screen resolution, the second seems to do nothing.

Passage between fields.
For each gateway:

Offset	Size	Data
0	6	Vertex 1 of exit line (maybe x,z,y)
6	6	Vertex 2 of exit line (maybe x,z,y)
12	6	Destination vertex
18	2	Field ID (or 0x7FFF if unused gate)
20	4 * 2	Unknown (or 0x7FFF)
28	4	Unknown (four equal bytes)

Doors interactions.
For each trigger:

In the PC version, you can sometimes see older versions of this format, there are three that are more similar to the format of Final Fantasy VII.

The first Unknown data are 4 bytes and there is no PVP field.

Same as 672 bytes format + the first Unknown data in Gateways are not present (like FF7).

Same as 576 bytes format + There is only one camera range and no screen range.
