@ DarkData: A difficulty mod that punishes players from grinding levels on SA? What do you expect? Happy rainbow feedback?
It's because other hacks aren't unfair bullshit hard. He calls them lolpatches.
A lolpatch is a patch that has little or no work put into it, or poorly thought out ideas. Unfortunately, FFT has many of those floating around, most of them 1.3 clones. A lolpatch has nothing to do with whether it is difficult or not!
HA! I remember that video. He threw a temper tantrum over it and said the guy cheated, even though he used totally legit means to win.
The video he's referring to is of an optional boss which was supposed to take 1 damage a hit (from anything) and had 999 HP. Video uploader found an exploit which let you do ~200 damage a turn to him, so it was fixed.
It wasn't meant to work that way, so it was patched the version after that. And yes, using that exploit was not beating the guy legitly. I still consider it cheating, though the exploit is no longer possible.
And yes, it works on real hardware.
