Since some things are scattered around, I guess it would be nice to link 'em all together in a single place, so hopefully I'll be active enough to keep updating this. In case you don't know what SDM/SVDT is... SDM (or Save Data Manager) and SVDT (Save Data Exporter/Manager) are essentially two different 3DS homebrew utilities that allows you to export (or "dump") any game's save data. Plus, we can restore/inject save data back into the 3DS without problems (there can be a few cases where there's a bit of technicalities involved). This allows the possibility to manipulate the save files in many different ways, such as infinite lives or collectibles; and later put that in the game. Before moving on to the main event of save editing and stuff, here are some essential utilities that you'll find useful in your 3DS Homebrew journey: Save Data Manager by profi200 (post by LinkMain111). Simple tool for the 3DS to export save data. Duh... SVDT by meladroit. Same function as SDM, but a bit more versatile. Haven't tried it out, so I can't give an opinion . EDIT. This has a special beta feature that allows automatic secure value updating, so the tool below can be omitted in some cases. Antisavegame Restore/Secure Value Updater + Rumble World Secure Value Updater by suloku. Useful computer utility that helps update the secure value of some games to avoid corruption/save rejection. It also has an extra tool for updating PKM Rumble World's secure value, due to its compressed file structure. (Tool currently supports: Smash 3DS, Pokemon XY/ORAS/Shuffle/Rumble World, AC:NL) Simplok for the Homebrew Launcher by link6155. An "icon pack" for the launcher, which changes the icons for various homebrew apps to clean, simple, cool-looking icons. The SMDH Creator by link6155 (Source code by GEMISIS). A forked version of the original "SMDH Creator" by GEMESIS. This editor has much more simplistic, user-friendly UI that allows you to make icons for your Homebrew apps with ease. If you're a Homebrew app creator, this will definitely help you out! Homebrew Launcher with Sorting and Folder Support by suloku. If you're one of those guys that prefers an alphabetical order or folders in your homebrew menu, then this one's for you guys! Now, without further ado, I present the editors: PKHeX by Kaphotics. Extremely useful tool that can edit almost anything you want in Pokemon XY/ORAS. Who's not gonna want this? Super Smash Bros. Save Editor by RandomUser. A simple save editor that allows you to unlock all characters (not DLC characters, of course), trophies, custom moves, stages, headgear, outfits, and powers; as well as edit Smash Run power slots & a few statistics. Animal Crossing: New Leaf Editor by marc_max. Special online editor that can edit your savefile by uploading it, editing it on the browser, and later downloading the new edited file. Animal Crossing: New Leaf Offline Editor by Kaphotics. In case you don't want to use the online editor, this downloadable editor can do just as much as the online editor, without the need of an Internet connection. Kid Icarus Uprising Save Editor by szymbar15. Editor that can unlock achievements and trophies, as well as change a few stats. Weapon editing is not available in this editor, due to the creator's choice; but you can edit weapons if you want (look below). Pokemon Rumble World Diamonds/P Tool by SciresM. This editor allows changing the number of Diamonds and P you have, as well as change your rank and your toy Pokemon's characteristics. Pokemon Shuffle Save Editor by SciresM. Another editor made by SciresM. Change the number of your usable items, caught Pokemon, stage scores, and more. Super Mario 3D Land Save Editor by DaBlackDeath. A simple editor that can edit the lives & Star Coins values for each of the 3 files available in the game. New Super Mario Bros. 2 Save Editor [WIP] by TheToxicRyu. This work-in-progress editor currently only allows changing the coin and lives value; but it will later have more features, as well as a level editor in the future! New Super Mario Bros. 2 Save Editor by DaBlackDeath. Made for his neice, this editor is also made for NSMB2. This is probably a similar editor to the one above, but this allows changing the Star Coin value! FireEditor FE:A Save Editor (WIP) by Olmectron. A currently-being-updated editor that allows the edition of certain components in Fire Emblem: Awakening. Requires Java. Sonic Lost World Save Editor by DaBlackDeath. Another simple editor from DaBlackDeath. Can edit the value of lives and materials. Told ya it was simple. Fantasy Life Save Editor/Viewer by mvmiranda. A powerful editor that can edit many values in the game, including character's name, pets' names, XP, bliss, etc. Monster Hunter 4 Save Editor by didix16. An online editor made specifically for MH4U. I haven't tried it, so I can't tell how good it is. Another MH4U Save Editor by APM. If you don't want to use an online editor, this one can get the job done. MH3U Save Editor GUI by Gocario. Pretty cool editor made to edit a lot of things in MH3U, like characteristics of the player, money, equipment, etc. Hatsune Miku: Project Mirai DX Save Editor (WIP) by Agent Moose. A work-in-progress editor that allows you to edit many aspects of this game. Right now, you're able to max out MP and unlock all songs. Bravely Default Village Save Editor by Oswarlan. A save editor that can edit your village's population and building level. Rune Factory 4 Save Editor by seikur0. This editor has a good amount of options to choose and edit from. I'm not sure if this is compatible with SDM/SVDT, since it requires .sav files. It does work with SDM/SVDT. Thanks, adiktus! Tharsis Forge (Etrian Odyssey IV Save Editor) Save Editor (WIP) by xdaniel. An editor that's currently adding in more features that allows the edition of save files of Etrian Odyssey IV. The following are not posts to save editors, but they have information on a game's save data structure. You can use any hex editor to do your changes. Be careful when doing changes with a hex editor, and ALWAYS backup your saves! Kid Icarus Uprising Weapon Save Hex Editing by TrapperKeeperX. This big guide contains loads of info for you to edit your weapons through a hex editor. Fire Emblem: Awakening by [Truth]. Simple instructions on how to edit values in FE:A.

A good number of offsets have been found. Nintendogs by drfsupercenter. Offsets for a few obtainable items have been found. Pokemon Dream Radar by shadowofdarkness. If you happen to use this, then you're in luck! Some good information, like Orb quantity & legendary unlocking. Dragon Quest Monsters by ethanej. Doesn't have much in there, but it may prove to be useful. If you're interested in the changes I made to the list (which aren't gonna be many of you), here's a nice changelog: Travel in time...

All save-data investigators for releasing info on a game's save structure. This helped some people when an editor wasn't available. All other programmers who were involved for releasing useful tools that helped us enjoy our homebrew/save editing to the max. All you guys reading for taking your time in looking at this odd post.
