Djibriel might, he had FF5 bugfix patches made by that person hosted on his site at one time.

Yes, I've been trying to find those patches for some time. I want to ask him if he could make an IPS with fix of my own, which would be implemented in my hack: http://slickproductions.org/forum/index.php?topic=247.0
Where can I find Djibriel?

This is the e-mail I sent to the author's hotmail address:

Quote from: me
In your guide, you mention a bug with the knives' damage parameters. You show ways of fixing the bug, and I have played through the game using both. I will try explaining why both methods has their weaknesses, and give you my suggestion for a fix. I was hoping you or someone you know could make an IPS file for it.
____________

Attack = Weapon Attack + (0..3)
M = (Level*Strength)/128 + (Level*Agility)/128 + 2
Defense = Defense
Note, due to a bug, only the first byte of (Level*Agility) is used (see Section 12)
______________

Meaning, agility does not affect the damage, except for a "random" bonus of 1 to M.

In the "Bugs" section, you explain how to tweak the game into using the whole byte. But you also explain that it gives a large boost to the weapons using those parameters. (Knives, bows, whips, etc.)
Then you show an alternative fix, which halves the smallest of the values "strength" and "agility".

Since only one byte is used in (Level*Agility), the bonus to M can only be 0 or 1 after dividing the value by 128. This means that mainly strength decides the damage of knives.
Assuming STR and AGL are equal:
The first fix you suggest gives a damage boost of around 100%, since two values are added to M instead of one. The second fix gives a damage boost of 50% since the fix is equal to the first, except one of the two M-bonuses are halved. In both cases, the damage gets increased beyond what it is in the original game. I personally believe it should not be increased at all, which is why I suggest this alternate method:

M = (Level*Strength)/256 + (Level*Agility)/256 + 2

The resulting damage will be the same as in the unpatched rom, except for two things; there are no "random" bonuses to M, and now both strength and agility counts equally.

EDIT: New formula: M = (Level*Strength + Level*Agility)/256 + 2
Gives the same result, but might be more accurate because the division is done at a later point.

I've always wanted to apply that bugfix patch.. but never got it.  :sad:

It is not the "same result" exactly. The math is done differently. Mathmatically, you can do that without penalty, but on the other hand, you are forgetting that truncation is being applied to all the division that goes on here. The formula in your edit is much more friendly/leniant. It is worth pointing out here.

Yes, that's the reason why I changed it. I meant that the result in theory is the same, but is actually more accurate because of the way the hardware performs division.

I found Djibriel's account at the CoN boards. I'm sending a PM now.

By the way, you can apply the fixes in the guide manually using a Hex editor. It requires a lot more work though.

here's the patches page from his old site:

http://tenchinohoukai.greatnow.com/patches.html

he gave me permission to host his FF6 patches on my site (and make needed tweaks to a couple).  one of these days, i'll get around to it.

As a suggestion, ask him to upload his fixes (and perhaps other hacks) to romhacking.net for preservation or whatever better reason you can come up with.

Ah, nice, nice. The fractional M patch will come in handy.
I will ask him if I manage to find him.

 The message tracker tells me that Djibriel has read my message, but he hasn't replied yet.

EDIT: There seems to be a bug in the M patch. When applied, Goblin punch (and possibly more attacks) does zero damage.
