Functions
void	FIGHTSTG_blendBone (Model model, ModelBone bone)
	Blends a bone's position, rotation and scale from the saved pose (FIGHTSTG_saveBlendPose) towards their first keys at or after the model's frame, by its blend; when either scale has a 0, the key's is taken as it is.

void	FIGHTSTG_poseBone (Model model, ModelBone bone, s32 frame)
	Sets a bone's position, rotation and scale to their keys at FRAME, interpolated between the keys around it.

void	FIGHTSTG_poseBones (Model model, Mesh *children)
	Moves the root bone by the model's move along its rotation, then poses (FIGHTSTG_poseBone) or blends (FIGHTSTG_blendBone) each other bone.

void	FIGHTSTG_saveBlendPose (Model *model)
	Saves each bone's pose as the one a blend starts from.

void	FIGHTSTG_setMotion (Model *model, s32 motion, s32 restart)
	Model.setMotion: lays out the motion's keyframes.

void	FIGHTSTG_stepMotion (Model *model)
	Steps a model's motion by the frames gone by, blending into a new pose where a keyframe has 0x8000, and starts the idle motion when it ends.

void	FIGHTSTG_updateModel (Model model, Mesh *children)
	The model's task: loads its textures and makes its meshes and face, then each frame follows its control's motion, steps and poses it, places the root at the control's position, builds each bone's matrices (a bone scaled to 48 or less is hidden) and queues its meshes on the control's layers; frees the bones when killed.

void	FIGHTSTG_setModelColor (Model model, s32 mode, CVECTOR color)
	Model.setColor: sets the color mode, and the color unless COLOR is NULL, of the meshes of each bone but the root (once for each of the control's enabled layers)

void	FIGHTSTG_addMeshPolyFT (MeshDrawState *state)
	The same as a flat-shaded textured triangle or quad.

s32	FIGHTSTG_isMeshOnScreen (Mesh mesh, Layer layer)
	Whether a Mesh may be on screen: the screen positions of the 9 points of its bounds against the layer's clip, 64 pixels bigger each way; noBoundsCheck skips the check.

static void	setMeshTexture (MeshDrawState *state)
	Sets the texture page, the CLUT and the UV offset from a command's bytes.

	A primitive tag's word with its address replaced: the top byte of tag and the low 24 bits of addr.

Detailed Description

The first object of FIGHTSTG.PRO, the models and their meshes.

FIGHTSTG.PRO was seven objects: each one's jump tables are aligned to 8 from the start of its own rodata, and they are 4 bytes past a multiple of 8 from 0x80082464 (USA) to 0x80082480, from 0x800825B4 to 0x800825D0 and from 0x8008267C on. Where each object's code starts is only known to be between the function with the last jump table of the object before and the one with its first; the last object (camera_task.c) differs between the versions. The second object is stage.c; the third to the sixth are cut into modules, in their link order (entrance.c to fader.c, lights.c and face.c, battle_script.c and first_tech.c, item.c to interp.c), each with its own rodata and data; a cut is only where each jump table keeps its place. Each object's or module's data is in its own file, in address order; the zeros that end the file, after the last object's data, are here.
