I have a solution for "Hard to Cheat On" stability testing.
Again, Wizzard, has a solution, and it can be found in his
Systool Program.
I tested this program in a few different ways, and I had a hard time cheating on it, see, with it's constant updating the list as to what passed and what didn't, I couldn't create a cheat that looked legit, cause it wouldn't match the next results...
thats very very good, for spotting cheats real fast.
manual cheating, and speed cheating did nothing to this program.
so it's about 90% cheat free, as far as I can tell. :D
