Giving the dark sword to 0 accuracy and setting bit 5 did nothing, it missed just as often as without it. I'm curious if the property only affects arrows because they're handled differently by the game, I'm going to test that next.

Bit 4 doesn't seem to do anything.

Edit: Rydia is just as inaccurate with Iron Arrows with the bit set too...maybe it only takes effect at higher levels? I'll do a test later in the game next.

Try it against enemy type weakness.

It is worth pointing out that if you do poor damage (1x whatever), you will be doing essentially be doing 0 damage aka Miss!

Did anyone ever figure out what the other 5 bits are for (besides Metallic, Throwable, and Long Range)? I tried doing my own tests, but couldn't see any significant changes.

Also, where is the info that determines which weapons are 2-handed? As far as I can tell it's not within the normal Item Stats Data. Is it specified somewhere else?

Have you at least looked into the comments/ideas that are in this thread? I'm pretty sure the critical hit ones are solid.. and maybe the ogre bit. I still have no clue what the Lightning Arrow's special bit is for...

You guys are using the data from FF2US or FF4 Super Famicom, right?

It's worth pointing out that none of those bits are used in FF4A, US version.  Only metal, throwable, back row are used -- there is no value higher than 7 in that field.

Those bits may not been as important.. or they may have been relocated elsewhere...

I have looked into the ideas in this thread, by activating those bits on other weapons and looking for those (or any) effects. But, they don't really seem to pan out, at least in my test cases -- I can't tell any difference at all. So, I'm not sure, either my tests weren't enough or they have some other meaning. It is interesting that they aren't there in FF4A...since they don't seem to have much of an effect on the game (that we can tell) it seems a likely possibility that they just removed them.

It could be recoded somewhere else.

After all, it only accounts for the strangeness in FF4A where the character takes strangely a bit too long standing there after the hit, as if checking the weapons and see if it is a match to cause special effects... even if they don't have a special effect.

Game logic shouldn't slow down the game to the point where you'd notice a lag -- that's just poor ATB engine programming in FF4A.

I don't think the bits were relocated.  Otherwise, there would be a set of 5 bits elsewhere in the item data that I wouldn't have pegged down.

http://entroper.no-ip.org/TheBatcave/FFRev2(2).xls is my reference.  There are some unused bits in the item flags, but they are just that -- unused, so they aren't the relocated bits.  I think they're just gone, unless there's a completely separate table somewhere, which seems unlikely.  More likely is that they never did anything originally.

Yeah, it seems likely to me that they were never used in the first place. At least, it appears that they still don't affect anything.

Also, nevermind about the 2-Handedness bit, I figured it out.

Another question on the 2-handedness:

I thought the bit signifying this was the 6th bit of the 7th byte of a weapon's stats (e.g. the Avenger sword's equipability byte is 27, 20 for the 6th bit being on and 07 for the equip index). Is this right? Because when I change it on any weapon I've tested so far, it doesn't change anything. Am I totally off on this?

I was reading your response to this and I looked into that myself...as there are quite a bit of mods to the weapons I'd like to make eventually...

Originally I thought the extra three bits in that "Who Equip" byte didn't mean anything, and just the first 5 bits specify the character according to the 32 values in the table at $07A750...

However When I expand all the bits and look at weapons and equipment there are patterns...

On weapons...
Only 2-Handed weapons (Axes, Hammers, Harps, Avenger Sword, Dummied Spare Sword) have bit5 set true.
Only Bows have bit6 set true
Only Arrows have bit7 set true.
No other weapons have any of these bits set.

On equipment...
Shields have NO bits set.
Only Helmets / Hats have bit6 set
Only Armor / Clothing has bit7 set
Only Gauntlets / Rings / Accessories have bit6 & bit7 set.

But your absolutely correct, changing these bits don't seem to have any direct effect on how equipment is actually "equipped" in the game menu.
I tried making a one handed sword 2-handed flipping bit5 on - no change
I tried making a 2-handed axe one handed by flipping bit5 off - no change
I also tried making a helmet an armor by flipping bit 7 on and bit 6 off, and again no change...

So it seems the "Equipment Type" and "Equip On Body How" data must be elsewhere. Although these bits seem like they could specify this somehow anyway...it's just not used by the menu system???

(BTW: I count bits as 7 - 0, and I'm using a headered copy of FF-II v1.0 to test.)


On the same issue...and I don't know if this has been mentioned elsewhere, but does anyone know where the data that specifies the "Fight" graphics are for weapons? As in a table or something that specifies the game to use what weapon graphic and palette for it, etc...?

I performed the same tests, and came to the same conclusions about both weapons and armor. However, the Bow bit (which I believe means the weapon is opposite-handed) seems to work. At least, I found greater damage when I turned that bit on and switched the weapon to another hand (I made Cecil ambidextrous for this), unless it was just my imagination. The Arrow bit (which means the weapon is expendable) also seems to work when turned on, if I remember correctly.

This is why I thought it was strange all the other bits didn't work. Maybe I'm crazy and those ones didn't work either, and I imagined it all . . .  :hmm:
