Alrighty. You can find a current patch and a very brief changelog here:
http://www.sixfortyfive.com/ps4arrange/
One patch is for .BIN roms, and the other is for .SMD roms. Download whichever one you need and use the Lunar IPS program to patch your rom. (Make sure to save a backup copy first!) The changelog is rather vague, so if you can't figure out how one of the items or bosses listed have been changed, just ask me if I haven't already covered it in this thread.
I haven't done much testing on this current version, and I plan on playing through from start to finish right now to see if all of the current changes are working and if the difficulty curve is reasonable. If anyone else is interested in giving this a whirl, I would greatly appreciate any bug reports.
EDIT: Well, I've already found a problem. Gryz's experience settings are screwy... Now to figure out why.
EDIT 2: Okay, for some reason, it's saying that Gryz needs 9.2 million EXP to reach his next level. For whatever reason, this happens to be the exact amount of EXP that
Rune needs to reach level 99. I've heard of this sort of thing happening to various characters in a normal playthrough, but it's an error that corrects itself when the character reaches the normal value for his or her next level. Supposedly, anyway. I'll keep playing for a little while and see if this goes away.
EDIT 3: Huh. Sure enough, Gryz leveled up to LV 6 when he was supposed to (1046 total EXP), and the NX counter looks normal now... I swear, PSIV's experience tables are the screwiest things ever.
EDIT 4: Oh ho ho. The changes to the Mile Sandworm didn't go quite as planned, but I think I like this accidental result better. I can't believe I beat the thing with an average party level of 7.
EDIT 5: Demi's EXP is also wrong. The NX counter lists the required EXP for Rika at level 98. I'm not sure what's causing this, but there does seem to be a distinct pattern. I expect that Wren's initial NX counter will list the requirement for Demi to reach level 97. I also expect this to straighten itself out again on each character's first level-up.
EDIT 6: Hm, the changes made to the Stun Shot work, but Demi doesn't show up in the attack animation. Oh well.
EDIT 7: Wait, no. It doesn't work
quite right. It can only put one enemy to sleep at a time... Maybe that's not too bad, as it keeps it from being overpowered. I'm thinking I might have to bump up its ATK boost a little, though.
EDIT 8: Okay, so Zio's Black Wave is an instant-kill move until the Psyco Wand is used. Might have to change that if I want that battle to be possible without it.
EDIT 9: Well, I don't know what to make of Zio. No matter what edits I make to his move list, he always uses Black Wave and it is always an instant kill until the Psyco Wand is used. I guess this is the specific effect that MAG BARRIR or NIGHTMARE actually causes.
EDIT 10: Note to self: remember to update the other instances of item names later.
EDIT 11: The Silver Rod's new use as an item does not seem to be working.
EDIT 12: Not to toot my own horn too much, but I am getting a kick out of most of the adjusted equipment. Most of it seems to work as intended and so far nothing seems to be throwing the difficulty out of whack in either direction.


EDIT 13: I think I may have nerfed the Spiral Slasher a bit too much when I implemented it. I need to bump its sleep inducing power back up to its default level. In other news, though, pairing a slasher with the Elecbarrier is great in mechanical dungeons. The Elecbarriers might be the most valuable items in this version so far; I'd hate to play through these particular dungeons without them.
EDIT 14: Aw crap, Lashiec's AI is screwed up. This answers one question I had but poses another.
EDIT 15: Alright, after a lengthy break (busy with school lately), I'm back at it. Here's an interesting discovery: Lashiec's REINFORCE attack stacks. That is, it increases all of his stats by 20 points every time he uses it, not just the first time. This is different from the stat boosts that are available to the player, as they do not have any effect when used a second time. (Well, that's not
technically correct, but it's a simplified explanation.) I'm just going to throw out a warning right now that even though you will be
able to sell the Psyco Wand in this hack, you probably
shouldn't.
EDIT 16: Whew, I managed to beat Lashiec at an average level of 24, but I had to restart the fight a few times and use up most of my Star Dews to do it.
EDIT 17: Okay, the Eclipse Torch is just a wee bit overpowered. Better scale that back a little.
