Steam ROM editor (FF6Tools)
I've started a Youtube playlist with examples of what is possible to modify. Note that none of these changes make a lot of sense in a mod, the goal here was more to test and show possibilitites.

In every version of FF6 (SNES and GBA) this is taken care in the code, it's a branch being made on a random number. The Steam version is no different in this regard, meaning that specific code would be in the .exe file.

No GBA code is read / executed by the .exe, it only read some of the ROM data.
Hi,

One of our fellow community member at ff6hacking[www.ff6hacking.com] has added support for the Japanese GBA ROM to his online editor FF6Tools available here[everything8215.github.io], meaning it is possible to load the Steam ROM and edit stuff!

He also has a OSX version that can edit more things for now and he plan to support the Japanese version in this version as well. I plan to come up with a guide to set up a OSX Virtual Machine and list the things that are possible to edit with both versions of the editor. However I'm quite busy with university so I plan to have the guide ready later this Fall. For now you can go to thew URL above, try to edit the Steam ROM and test your edits in the game!

Note that not everything you'll edit will work in-game. The game does not use all the ROM data for running. I listed in 2016 some things that were working after a single or two test(s) edited manually in a hex editor. Lines with a T means the test was succesfull while lines with a U means that data is either untested or changing that data result in no change in-game.

Here's the list:

Side Battle Character portraits mod

I guess you (or OP) could resize the portraits or a part of them to 32x32 and use this instead of original portrait files?

Disappointment about mods
Anyone who know how to use a hex editor can make significant changes to the GBA ROM inside the archive and modify battle formations, chests, character initital stats, monster stats, monster AI, spell data, metamorph packs, item data, etc. All the required info is on the internet.

Editing the OBB Japanese ROM
This info might be already know by some people. I started a FF6A (U) Editor in 2013. Right now I'm working on a new version with more editable data and I'll add support for the (J) ROM, the one used in the OBB.

In the meanwhile, you could use my editor FF6AE[madsiur.net] with a (U) ROM for character stats, item, magic and monster data and copy with a hex editor the data to the OBB ROM. The goal of this post is not to give a hex editor tutorial, there are plenty on the web. All four data are at the same place in the ROM, expect for monsters stats. You can forget the font edition obviously with the FF6AE editor.

Here's the comparison between both version:

(U) Data -------- 62ACAC-62B22A DATA Character Initial Statistics (22 bytes * 64 entries) 62BC34-62CC1D MAGIC Magic Data (14 bytes * 291 entries) 73798A-73AE6A MONST Monster Stats (32 bytes * 423 entries) 62CC64-62D6EF ITEM Weapon Data (30 bytes * 90 entries) 62D6F0-62D8B1 ITEM Shield Data (30 bytes * 15 entries) 62D8B2-62DBDB ITEM Helmet Data (30 bytes * 27 entries) 62DBDC-62DF7D ITEM Armor Data (30 bytes * 31 entries) 62DF7E-62E06D ITEM Tool Data (30 bytes * 8 entries) 62E06E-62E103 ITEM Skean Data (30 bytes * 5 entries) 62E104-62E775 ITEM Relic Data (30 bytes * 55 entries) 62E776-62EA45 ITEM Item Data (30 bytes * 24 entries) 62EA46-62EA63 ITEM "Empty" (30 bytes) 62EA64-62EC26 ITEM New Equipment (30 bytes * 15 entries) (J) Data -------- 62ACAC-62B22A T DAT Character Initial Statistics (22 bytes * 64 entries) 62BC34-62CC1D T DAT Magic Data (14 bytes each * 291 entries) 62CC64-62EC26 T DAT Item Data, regrouping weapon, armors, relic, etc.. 7379A6-73AE86 T DAT Monster stats (32 bytes each * 423 entries)

If you want to take it one step further, you could edit a SNES ROM with FF3usME[www.ff6hacking.com] and copy the hex block into the OBB ROM. Most formats, as far as what FF3usME cover are the same as the GBA versions. To know the location of the data in the SNES ROM, you can check this ROM map[www.ff6hacking.com] and cross reference with the OBB ROM[madsiur.net]. Stuff like formations, shops, esper data, colosseum and more can easily be edited this way. Note that FF3usME does not cover the GBA extra content (duh).

Thing that require pointer changes (variable length data such as monster AI will be more difficult to modify if you add more bytes to an entry than what it originally had, i.e. this would require changing all pointers starting at the entry index).

For more info on the GBA / SNES formats that are identical (mostly what FF3usME covers), you can check this page[www.ff6hacking.com].

For now, these are the easiest solutions. Once you get comfortable with an hex editor, transfering data is easy. For a decent free hex editor, you can look for HxD on the web. It has copy/paste features and you can have opened multiple files at once.

Once I get a 1.0 release of my new editor ready, things should be easier as you'll be able to edit directly the OBB ROM. I hope this post will be useful to some people.

Final Fantasy VI Modding
Originally posted by Saftle:

Yeah that could be an option. What I did is making two copies of the font and renaming them arial.ttf and Arial-Bold.ttf (I wasn't sure if both were used by the game and Arial-Bold is a much larger file). Does the game use only arial font? I also have 4 other font listed in the obb, Roboto and Roboto-Bold keifont and I_10646. What is the use of these?

Second thing that bugs me is the font license. It is uner the license of "Free for personal use". Does releasing a patch for free that contains it for a video game goes against that license? The designer company who created it is closed since 2003[moorstation.org].

Also I'd like to know if a "font expert" could tell if any character is missing from the font for the different language selection of the game? The complete char list can be found here: http://www.azfonts.net/load_font/chicagoflf.html

If all those question are answered positively, I'd be happy to make a patch!

I've never looked into those. Ha yes, the characters names are not from me, it's from a savefile I begged in this discussion.
So double post since I did not know where to put this... I tried the ChicagoFLF font in-game and wanted some general commentaries on how it looks. It's a complete Latin font I think as far as English, Spanish and French are concerned (maybe more).

The original FF6 uses the Chicago pixel font. I just wanted to see how looks a more modern version of the font in a more modern version of the game. I guess the font could be in a higher resolution, the TTF file size is rather small (48k). I'm not planning for now to release a mod for it or work on this, unless there's a real demand. Also I have no experience in font creation/modification.
