DSK file

A .dsk (Demo Scene Key) file is used by Pikmin to make moving cameras and other key-framed movements present during cutscenes. The file is plaintext, but has a lot of floats and other values. .dsk files can be found in /dataDir/cinemas/demo*. Sometimes there will be multiple of them. In cutscenes that have text show up, the first is usually the main cutscene and the second is for the frozen camera while text is up. Any other .dsk files you see are likely unused. You can use Dolphin's file monitor log to see what files are loaded by what cutscenes.

Example of .dsk file

This is the cutscene for waking up at The Impact Site on day 1 (demo03):

Explanation

The first part of any .dsk file is <SCENE_KEY_ANIM_INFO>. The majority of this segment is development creation data, like the time and directory, that don't do anything. So far, the only thing here that I've found does anything is numcameras which crashes the game at 0. (It is possible "playmode" has an effect too.)

After this is <KEY_CAMERA_ANIM>. This segment is nothing more than a bunch of floating point numbers. At the start is the number of floats present after it. Don't think anything of the number of floats per line, it doesn't mean anything. Changing these floats will change how the camera behaves during cutscenes.

After that is what actually assigns all those floats in the previous segment, <KEY_CAMERA_TABLE>. This segment is made of 12 lines.

List of parameters

Name	Description
index	Index of this camera, used when there are multiple cameras in a cutscene. This should always be 0.
name	Name of the camera, which is seemingly used by other segments of the file.
cam_pos_x	X value of cameras location.
cam_pos_y	Y value of cameras location.
cam_pos_z	Z value of cameras location.
cam_lat_x	X value of where the camera is focused on.
cam_lat_y	Y value of where the camera is focused on.
cam_lat_z	Z value of where the camera is focused on.
cam_twist	Camera roll axis?[unsure] (usually left at 0.000000).
cam_fovy	The field of view of the camera.
cam_near	Near culling distance of camera (doesn't work?[unsure]) (always 0.100000)
cam_far	Far culling distance of camera (doesn't work?[unsure]) (always 32768.000000)

After all of these parameters is a set of 3 values; these control how many floats from the float table above are for each of the parameters. The right value is always 0. At first I thought this matched the value with the index of this camera, but it seems that even when there are multiple tables it stays at 0. Changing it can break the cutscene, so it clearly does something... The middle value is the highest index float this parameter uses. Keep in mind they can technically be anywhere in the file, and multiple parameters can use the same floats. The left value is the number of floats used for this parameter, counting backwards from the middle value.

Other

After this are many other minor segments, such as <EX_SI_KEY_CAMERA_ANM> and <EX_SI_KEY_CAMERA_TABLE>. These two are seemingly always present, although the former is always empty. The latter uses the camera name to connect to the main camera, as described before, but it is unknown what it actually does.

<KEY_DIFFUSE_LIGHT_ANM> and <KEY_DIFFUSE_LIGHT_TABLE> work in a similar way to the camera movement values, but control lighting. They have different parameters in the table though, so I will put them here too.

List of parameters

Name	Description
index	Index of this spotlight, used when there are multiple cameras in a cutscene.
name	Name of the spotlight, which is seemingly used by other segments of the file.
light_type	Unique to lighting, not quite sure on this one yet.[unsure]
light_pos_x	X value of spotlight location.
light_pos_y	Y value of spotlight location.
light_pos_z	Z value of spotlight location.
light_r_param	Amount of red in spotlight.
light_g_param	Amount of green in spotlight.
light_b_param	Amount of blue in spotlight.
light_visible	Amount of alpha in light. (always 255.000000)

The three values after each parameter work the same here as with the camera, although they are usually much simpler, if even present at all.

Lighting also has its own <EX_SI_KEY_CAMERA_ANM> and <EX_SI_KEY_CAMERA_TABLE>, which seem equally strange and unknown.
