Skill points are 4byte*1. Get 3 points, use one, search 2 and you should only have one result.
Should be enough to get all the medals, I got almost all them in one run. Just missing "make your first 50 shots" and don't spend any skill point and reach level 10, which shouldn't need a hack, very easy.
If you can't, post and somebody can prob make an invincible hack.
