im not good at searching mem :S but here is how i do it...
I use ArtMoney to search my memory (only search... ! )
lets say your current hp is 3347 ...
Search for the value 3347 in memory ... many results will pop up...
now use a buff or so to change your current hp.... new HP is 2247
now filter your results from search for the value 2247...
got it?
