• Changer - Red/Blue "changer". Not sure what it means by that, really. My guess is it's just a pokemon editor. Requires knowledge of the hex values for each pokemon.
• Complete Item Changer - Exactly what it sounds like. Third gen only.
• Complete Multi-Choice Box Editor - Simple tool for editing the multi-choice boxes in FR/E. I assume it also supports LG but not sure.
• G2Map - Map editor for G/S/C, written in C# with .NET 4.5. This means you must have .NET Framework 4.5 installed to use it! Capable of editing maps, events, map properties (tileset, music), and wild pokemon on maps that support them. This program is not perfect, it does have its quirks.

FFHacktics tools page

Demo and significantly buggy editors not listed.

The majority of FF7's tools can be found on Qhimm, and they're unusual in that they mostly work for both the PS1 and PC files (both games use a similar file architecture, enough that tools can generally cover both versions). They're also available from Qhimm, but can be tough to find. One important thing to note is that the PS1 version has file size limitations; make sure to ask around on Qhimm before starting a mod project for the PS1 version to get a better idea of what the limitations are and how to work within them.

-) Proud Clod (PrC) - Enemy/Formation Editing Tool

This edits the scene.bin of the game, which contains all information pertaining to enemy data. You can pretty much change everything; their attacks, stats, AI, formations, etc. The current/final version should be able to edit everything without a problem but be wary of using the 'synch current [enemy] with other scenes'; this would have been a huge time-save if it worked but it unfortunately corrupts formation data.

Before using PrC, make sure it has admin permissions and is unblocked, etc. It needs to access the game's Kernel to 'update' it when enough changes have been made as the game has look-up tables that need to be updated when the size of either file is altered by a certain degree; otherwise you'll have Safers swarming about in the first Reactor and other wrong encounters loading.

-) Wall Market - Kernel Editor

This edits the game's Kernel, where player character stats, Materia, items, equipment, spells, key items, and character AI are stored among other things. Unfortunately, this editor is prone to text compression errors as the size of the kernel gets larger and is subject to much tighter size restrictions even for the PC version. You may find when working up to the size limits that text can be suddenly corrupted or will be mysteriously edited (garbage strings can be displayed, or all instances of the word 'Holy' will be removed for instance).

Getting Wall Market to work can be hassle, as it was made using Visual Basic so certain file dependencies will be missing from your computer if it's new. You can find these individually through a .dll site but the smarter thing to do is find the free Visual Basic pack on Microsoft's website that contains your missing dependency files and to install that instead. When making changes to the game's kernel, remember to synch it with the scene.bin by opening PrC and synching them there (Wall Market doesn't have that function).

-) Makou Reactor - Field Script Editor

A very powerful and useful tool, this opens the game's scenes and lets you not only alter the game's dialogue but the actual game script itself as well. You can make custom scenes or edit existing ones, change the field music, animations/actors used, even the scale of the walkmesh for faster/slower movement. The tool access the char.lgp so any mods applied there will be displayed and can be used with the tool; it can also search through the game's script for text or variables, allowing you to make quick changes or to check up on any used entries.

There are a few kinks in the tool though. Sometimes a changed actor model will revert after leaving the sub-menu, or field can be corrupted if exporting/importing them (the 1.5.1 release seems to be able to do this without issue).

-) Kimera - Model Editor/Viewer

This is PC only, as the models for the PS1 version are kept in a different format and are very hard to edit. This tool also requires visual basic dependency files so be prepared to search for some before you can run it for the first time. It also requires that the .lgp archives where the models are stored be decompiled beforehand (use Luksy's tool for this).

Kimera can modify the battle and field models of the game quite handily, though it requires a fair amount of practice to become proficient with. It can change colours fairly easily, scale/rotate individual parts, edit and interpolate animations, or add/remove parts to the skeleton to make 'unique' enemy models.

-) Libre - Limit Break Editor

An old and ancient tool, this requires file dependencies to work and even then it'll still be touch and go. As Limits are stored in the game's .EXE and not the kernel (only part of the data is stored in the kernel, editing them there won't actually change them), Libre accesses this to make changes to each one. It has a few things to watch for, namely that Braver can sometimes get overwritten by Satan Slam so be sure to double-check it after saving/closing your work. As old as it is, it's still the only Limit editor out there.

-) White Chocobo - Shop Editor

Like Libre, this tool is very old and even more unstable than Libre is. Shop inventories are stored in the .Exe as are the selling prices for each and every item/Materia in the game. The tool is effective at what it does; it lets you change what's for sale, for how much, and has notes on which inventories are unused, etc. However, due to the age of the tool you may find that it becomes inoperable after one use.

-) ULGP - LGP Archive Extractor

Very important tool for using Kimera, this will decompile an .lgp archive and allow you to edit the files individually. It will also recompile them once you've made your edits.

-) IMG2TEX - Texture Converter

FF7 mostly uses shaded polygons for it's models, but these are accompanied with texture files (eyes for instance). This tool converts these into a file format workable in most image editors and then lets you convert them back for use in the game.

-) Doomtrain – Kernel Editor

A relatively new tool, this extracts the kernel.bin from FF8 and allows for the editing of everything from Limit Breaks to Junction effects, allowing for much more freedom in modifying the way FF8 will behave in-game. The Deling tool is required to extract the required file.

-) Deling – Field Editor & File Extractor

This tool is the backbone of most FF8 editing in that it doubles not just as a field script editor but also as a file extractor. Note that this tool is still in Beta, unlike its sister tool Makou Reactor.

-) Ifrit – Enemy Editor

Modifies enemy data for FF8, though some functions such as AI editing are still quite rough.

-) Junkshop – Weapon Editor

This tool allows for the modification of crafting requirements for various weapons, and their prices.

-) Quezacotl – Initial Data Editor

This tool modifies the starting data for the player; included are initial statuses, level, GFs, Magic, Abilities, Junctions, and Limit Breaks.

-) Cactilio – Battle Formation Editor

A tool to edit enemy formations.

-) Hades Workshop – General Purpose Editor

From enemies to items, and texts to field scripts this editor covers most of the features in the PC and PSX versions of the game.

~Paper Mario Kirigami64 (Originally titled Origami64)

This editor for Paper Mario allows you to edit the text in game and the enemy formations. This editor is still being worked on for more features. The only thing is you need a .z64 file instead of a .n64 file.

~Mario Improvement 3

A basic level editor for SMB3.

~SMB3 Color Editor

An editor that allows you to change Mario and Luigi's palettes

~SMB3 Discombobulator

A level editor that allows you edit the overworld maps.

~SMB3 Map Editor

~SMB3TE

An editor that allows you to edit the title screen

~Super Mario Bros. 3 TSA (Tile Square Assembly) Editor

MegaED X

An editor capable of changing most of the preset collisions found in each of the stages in Mega Man X. With this tool, you can change the content of the scenes, tiles, palettes and collisions

WindHex32 - Hex editor with table support.
HxD - Hex editor with copy/pasta features and overwrite/insert mode. This is the hex editor I use, if you're curious.

For Earthbound, use Coilsnake. It's pretty comprehensive, newer, easier to use, and more powerful. It essentially extracts data from the ROM into a set of relatively easy-to-edit text files and, when you're done, recompiles it all. It takes care of redirecting pointers and things that like for you. Since version 2 it's been bundled with CCScript (for changing dialog and events, even doing ASM hacks with much less hex editing if you're good with it) and EB Project Editor (for map modding). You can add custom CCScript files in with the ones extracted by Coilsnake and it will integrate them on the fly during recompiling. It looks like it's also bundled with methods to expand the ROM now as well, which is neat. It's your go-to for hacking.

The last time I was playing around the EB hacking there were a couple things it couldn't do or things it did worse than the alternatives (PK Hack, EB++, and JHack), but that doesn't seem to be the case nowadays. Check out tutorials and give the Coilsnake thread a quick skim if you're curious about whether it can do something. Link to Coilsnake and PK Hack, plus tutorials and other EB utilities: http://starmen.net/p...oads/utilities/

Also, there's a really nice repository of info in the forum on starman.net (Link: https://forum.starme...ommunity/PKHack) with several good summary threads. Also in there is an awesome compilation thread with custom bits of CCScript/ASM scripts that senior hackers wrote for other people to use. When I was working on EB hacking, that seemed like a pretty great community as long as you're willing to put in your part of the effort.

Finally, the Data Crystal pages for Earthbound are pretty good. They're probably not that necessary unless you're doing some really deep hacking, but the various data maps there are a decent place to start. They're not loading for me right now so I can't make sure I'm linking the best place, but the main page is at: http://datacrystal.romhacking.net/wiki/EarthBound
