I haven't quite read all of what has transpired, but lighten up a bit Kuugen. He is only attempting to help you solve your problem, you don't need to get angry at him.
As for the program itself LGP/UNLGP is superior to LGP tools because LGP tools has a tenancy to corrupt the LGP files, or maybe it was just the Magic.LGP, I am not entirely certain. As for your hardcore scene, have you actually tried using the UNLGP program to unpack the the flevel file and then recompiling it with the LGP binary? If not, you should. When I modded FF7 I had a lot of trouble with LGP tools, and the LGP and UNLGP tool made by Aali made all the difference.
Again, I haven't touched it in quite some time, so I may not have my facts straight.
And there was another one that I used, that worked. Not the installer made by sithlord48, but just the files produced by aali, using batch files to run them. And the reason we don't link you to it, is because we don't want to go searching through the forums to find it, we merely point you in the right direction so you can you use the search function for its intended purpose (Even if the search function has been faulty lately...).
But, again we are only attempting to help you, you shouldn't attack us because our results aren't satisfactory... It's not like we're being paid.
When it comes down to it, if you have a problem you really have to learn how to fix it yourself. We are here to help you along the way as a modding community, but you can't rely solely on us to fix all of your problems.
