i remember on forum was a thread with mob / char speed script and with edits to can make it 2x , 3x times faster and things like this let me search it and i will come with edit
This is what 66drako66 posted:
Point 1. The normal speed of mobs without hacking ranges from 3 to 5, while your own speed is 2.6 (without skills).
Point 2. You will need to find the line in the mob speed script that says "db 00 00 20 41"
Point 3. Now you need to learn the hex equivalent of the speed values.
here I provide the values you should be using:
00 00 00 00 = 0
00 00 80 3F = 1
00 00 00 40 = 2
00 00 40 40 = 3
00 00 80 40 = 4
00 00 A0 40 = 5
00 00 C0 40 = 6
00 00 E0 40 = 7
00 00 00 41 = 8
00 00 10 41 = 9
00 00 20 41 = 10
00 00 30 41 = 11
00 00 40 41 = 12
00 00 50 41 = 13
00 00 60 41 = 14 //any faster than this, and the mobs might start getting lost
