Hi there.
First, let me preface this by saying thank you for the hard work you put into your trainers. They don't always work the way that I would expect, which is typically pretty fun because it requires thinking about workarounds to the problems, giving new opportunities for different styles of play, and that's awesome.
I just wanted to throw some feedback to you. I am using the +15 version of this trainer, and while I can't speak for the stat value modification (I haven't yet tinkered with that), I can say that every function so far works for me.... except Set Gil. I have tried everything I can think of to make it work more than the first time it did, and I cannot, for the life of me, do it. I've been settling for doing Infinite Items + Throw Command, which results in 99 of every throwable item, and then selling them all down to 1 each to repeat the process, but this would be so much easier if Set Gil worked as intended.
