The names section contains a list of actors by name, followed by a hyphen (-), followed by a 16-digit hexadecimal number. This also includes some plaintext parameters for some objects, such as the contents of a chest (ObjTreasureBox) or the destination of a loading zone (AreaLevelOpen). Note that these do not define what actors exist, in fact it seems like the actual labels here are meaningless aside from the aforementioned parameters. | The names section contains a list of actors by name, followed by a hyphen (-), followed by a 16-digit hexadecimal number.

The data section contains, among other things, blocks of 0x98 bytes, one for each actor in the room. Preceding this is a u64 which specifies the number of bytes the actor data section takes. | |||

|'''Parameters'''. This section contains multiple u32's, which appear to be grouped into pairs of [parameter, parameter type]. | |||
For any pair, the first 4 bytes make up the value of the parameter. This can be basically anything (will include some known parameters for certain actor types below). | |||
The second 4 bytes indicate what the purpose of the parameter is. There are only 3 observed values so far: | |||
* 0x0, which indicates the parameter is not used? | |||
* 0x3, which indicates that the parameter is a direct parameter. e.g., the parameter 0x1 is used to indicate being able to push a block actor. | |||
* 0x4, which indicates that the parameter is a plaintext parameter specified in the names section. The value in the previous u32 is the offset in the names section for this parameter. | |||
Most actors have "blank " parameters filled in offsets to the 2nd null byte after the first label in the names section; however, this seems to be functionally equivalent to leaving the parameter as 0. | |||
