Integer Division

Some divisions are optimized into a multiplication and a shift.
The result of the mul operation is in two combined registers [edx:eax].
The value of edx is result/0xFFFFFFFF.
This optimization takes advantage of that fact:
(value*multiply/0xFFFFFFFF)>>shift =>; value*original

A multiplication followed by a division is sometimes optimized the same way.

Multiply	Shift	Original
0x069C16BD	0	665/25756
0x10624DD3	4	1/250
0x10624DD3	5	1/500
0x10624DD3	6	1/1000
0x2AAAAAAB	0	1/6
0x30C30C31	3	1/42
0x38E38E39	1	1/9
0x4EC4EC4F	3	1/26
0x51EB851F	5	1/100
0x55555556	0	1/3
0x66666667	1	1/5
0x66666667	2	1/10
0x66666667	3	1/20
0x66666667	4	1/40
0x66666667	5	1/80
0x66666667	6	1/160
0x66666667	7	1/320
0x66666667	8	1/640
0x6BCA1AF3	5	1/76
0x88888889	8	1/480
0x92492493	3	1/14
0xA0A0A0A1	7	1/204
0xAAAAAAAB	1	1/3
0xAAAAAAAB	2	1/6
0xAAAAAAAB	3	1/12
0xAAAAAAAB	4	1/24
0xAE147AE1	5	17/800
0xB21642C9	5	1/46
0xB60B60B7	5	1/45
0xBA2E8BA3	3	1/11
0xEA0EA0EB	0	32/35

Note: these optimization are only used if the resulting value doesn't lose precision in comparison to the original operation.

EFST

These values appear to be like the SC_* values in eAthena.
Unknown info is read from ".\scriptbin\buff.bin".
The meaning of the internal fields is unknown.
See the comment to know how each EFST is set.

Values:
???
???
isSave 0/1 - if the status is saved?
isSendPacket 0/1 - if packet 0x196 is sent
???

Pushback

Pushback consists of an object being pushed in the direction of a reference position for a certain distance.
It's a side effect of certain skills, like Jupitel Thunder.

src - current position
ref - reference position
range - how much to push
dx - push increment for the x coordinate
dy - push increment for the y coordinate

The implementation can push in 8 directions.
The direction is determined by the position of ref relative to src.

if( abs(ref.y-src.y) >= 3*abs(ref.x-src.x) )
{// vertical
  dx = 0;
  dy = (ref.y > src.y ? 1 : -1);
}
else if( abs(ref.x-src.x) >= 3*abs(ref.y-src.y) )
{// horizontal
  dx = (ref.x > src.x ? 1 : -1);
  dy = 0;
}
else
{// diagonal
  dx = (ref.x > src.x ? 1 : -1);
  dy = (ref.y > src.y ? 1 : -1);
}

It pushes until the target range is reached or an unmovable cell is found.

for( ; range > 0; --range )
{
  if( !is_movable(src.x+dx, src.y+dy) )
    break;// not movable
  src.x += dx;
  src.y += dy;
}
