DCA files, likely standing for Demo Cutscene Animations, are the keyframed animation format of Pikmin. They can only be found within the BUN file format.

File structure[edit]

DCA header
Offset Size Purpose
0x00 4 Amount of joints the file will animate.
0x04 4 Amount of frames in the animation.
Scaling
Offset Size Purpose
0x08 4 Amount of scaling values
0x0C 0x08 value Scaling value
Rotation
Offset Size Purpose
0x0? 4 Amount of rotation values
0x0? 0x0? value Rotation value
Translation
Offset Size Purpose
0x0? 4 Amount of translation values
0x0? 0x0? value Translation value
DCA joint
Offset Size Purpose
0x00 4 Index of the joint
0x04 4 Parent of the joint
0x08 24 Internally named sx_param and sy_param, a table of 2 ints read 3 times
0x20 24 Internally named rx_param and ry_param, a table of 2 ints read 3 times
0x56 24 Internally named tx_param and ty_param, a table of 2 ints read 3 times
