I don't think your quite getting it. What LFSTweak and LFSTune do is edit memory in real time, not a simple task as not only do you have to find them in the first place, but you have to figure out the data type used, and then overwrite that memory with your value. But to make things even worse, on each update of the LFS.exe application the memory locations change, so you have to sort that all out again!
