← Gotcha Force

This article is about Gotcha Force mot.bin file format and ongoing researches on it.

This file format needs more research.
This section is currently being written.

MOT files are files packing motions files.

Format

Gotcha force motion files use the same file format than Smash Bros investigated by its community.

Motions files are HSD files from the library Hal SysDolphin. MotFile file format are files that contains groups of motions. Each motion is applied on a model at runtime by the HSD engine.

Positional empty files suggest that the game engine use specific motions for each position.

groups header

groups_header - list of uint32 offsets pointing on groups of animations (offsets list)

fixed length = 64
empty groups (0x00 00 00 00)

For each group: group_header

group_header - list of motions offsets

-1 terminated (0xff ff ff ff) and not aligned
total group_headers are aligned to 0x20

Motions files

each files aligned to 0x20
first uint32 corresponds to the total file length
