So anyway, the patch and a readme can be grabbed here if you'd like to give it a whirl:

PSIV Arranged Version is a slightly more difficult version of PSIV. The main differences include a significantly slower EXP/MST gain in addition to new item and weapon uses. The goal of this romhack is not to force the player to grind for more levels and cash, but simply to force him or her to examine dozens of options that the game makes available to the player that may have otherwised been overlooked in a normal playthrough.
I've played through the finished romhack myself to make sure that the difficulty is reasonable. I had to grind for a few levels in exactly two instances: before the Zio fight, and before the final boss. While much of the game is difficult when you aren't slowing down to grind, you'll rarely need more than proper equipment and tactics to pull yourself through. I used savestates throughout the game for convenience, but never in the middle of a battle. There's no reason why you shouldn't be able to play through the entire game without them at all.
The readme discusses most of the changes in greater detail. I feel like there's other things that I should be mentioning but can't think of right now. At any rate, if you're interested, I'd appreciate any comments and feedback.
