I went with a different approach in finding dmg hack. I used 2 weapons of the same level, one with no stats and the other with skill dmage + 2. I was able to narrow the addresses down to 7, tried each one and didn't get any result.
@Dwar, can you give a hint on range hack? Not sure where to start as the game is too restrictive that you can't attack w/o a weapon.
Thanks
