Could you please describe your problem in proper english? It's really hard to understand what do you mean, so I'm going to ask you a question to clear it up -
1. do you mean a hack that other players will hardly notice (if yes, then simply use chams & no recoil feature in the MPGH pub and don't just look thru the walls, instead act like normal and when going around corners - look to the side where the enemy is, instead of aiming at his head thru the wall, even while moving).
2. perhaps you mean a hack that is undetected and doesn't crash when loading (if yes, then simply try all the newest hacks)?
