Well, I guess Magic Knight's gonna be the best fit here!
How about changing "Precis.%" into "Accuracy" and deleting the redundant % in "Evasion%"?
I will do that! Funny thing is, the DS version doesn't even display Accuracy in the stats screen, so I went with the term that was used in the GBA version of Final Fantasy IV (yes, IV lol); I now realize that that's silly since Square Enix themselves are inconsistent with the terms they use for stats in their official releases (also I just found out, the DS version of FFIV calls it Accuracy, which gets the point across a lot clearer IMO). And the reason why I had the "%" there after Precision and Evasion is just for visual continuity with the SNES version of FFIV, but I can see why some would think it looks weird so I'm probably gonna change it.
Are you doing extensive asm hacking on this game, or just changing some bits here and there?
There's some cosmetic changes that could be possible with some assembly, but I don't know if it's worth the effort, so...
I'm not sure what qualifies as "extensive ASM hacking", but nonetheless there has been some light ASM hacking involved, such as getting the game to load the text banks from the added PRG banks (I had some help from Disch with that
). I've also had to do some light ASM hacking to expand the sizes of the menus, usually it just involves me setting breakpoints on certain offsets while taking a look at FCEUX's PPU viewer and finding the relevant code that controls the menu sizes from there. There's also a bunch of small byte changes I've had to make to expand the windows in the battle menu and the little 'transition' animations they make when disappearing to display another menu.
As for the actual content of the menus themselves, no ASM is required to rearrange stuff because believe it or not, almost every menu in FFIII (also FFII, which I can confirm, and most likely FFI too) is controlled by really large text strings. For instance, this is the actual text string for the Stats menu as it is right now:
[0F]Job Level [3D]
Level [3E][8E]XP 
For Next Lv.:[FF]
[0D]Mag.Eva [.] 
It's really easy to alter the actual content of the menus themselves to whatever you want, as they're controlled entirely by text strings:
So if you have any suggestions, I'm all ears. Though I'm satisfied with the job title character limit as they are now, because the 12-character job titles that I've achieved sounds like a miracle compared to the 7-characters that they were limited to in the vanilla Japanese ROM.
EDIT: Did some tinkering with the Stats menu and ultimately settled on this:
EDIT: Tonight's update:
Also, this is how the magic-menu will look like in-battle:
(and let me tell ya, hacking the battle menus in FFIII is like 1000x easier than FFII because FFII uses that sliding battle menu with complicated coding, while FFIII's battle menus are a lot more simplistic coding-wise)
