How to use 3DS Save Editor

For the 3DS savegames are stored much like on the DS, that is on the FLASH chip in the gamecart. Over the DS these savegames were stored in plain-text but on the 3DS a coating of encryption was added. This is AES-CTR, as the contents of several savegames show the odd behavior that xor-ing certain elements of the savegame together will lead to the plain-text appearing. The good reason this works is basically because the stream cipher used has an interval of 512 bytes. That is to say, it will do it again the same keystream after 512 bytes. The way you encrypt with a stream cipher is you XOR your computer data with the keystream as it is produced. Unfortunately, if your streamcipher repeats and you are encrypting a known plain-text (inside 3ds save editor 2 our case, zeros) you are basically giving away your valuable keystream. So how do you utilize this to decrypt a savegame on a 3DS? First off, you chunk in the savegame into 512 byte chunks. Then, you bin these chunks by their items, discarding any that contain only FF. Look for the most common chunk now. This is your keystream. Now XOR the keystream with your original savegame and you ought to have a fully decrypted savegame. XOR with the keystream again to create an encrypted savegame. This save editor does have bugs, one being that it modifies the save files it opens directly, so make a backup of the save file before opening it with this editor. This editor is written in an exceedingly old vocabulary also, should still work for what it is intended to do however. Another source was used by me program written in the said language as a template, and made this Editor. When someone else create an SSB3DS editor and release it, that editor shall probably supersede this one. Keep in mind that you are allowed by the editor to obtain all move pieces, headgears, and clothes, in a very crude way. It simply writes "FF" to the positioning of the save document that enables this stuff. I really do not know if Nintendo can ban predicated on what is written on the save document or not, so keep that in mind, that it's very noticeable when looking at it in a hex editor. I have compiled version 2, but thought it was not sufficient for release as the transparent feature had not been working and the DLC personas were released before I possibly could release it. THEREFORE I bumped it up to version 2.5, because the DLC individuals were added in to the list. Now it is possible to edit your Power equipment in your custom personality slots (a character must be saved to the said slot machine to be modified). It is best to customize your personas, and give it equipment before using the Power editor menu. THE ENERGY editor menu can and can make your heroes obese, as it gives you to bypass the wight limit of the amount of forces you can equip in smash run. Using the unlock all specials feature is recommended to completely make use of the capabilities outfitted for smash run highly, else all the ones you did not earn will be died out. The SSB3DS save editor has grown in size unfortunately, and the old program writing language cannot be supported. So version 2 now.5 requires .Net framework version 4 to run. Again all the pests remains as well as perhaps some new ones still. I compiled both 32 bit and 64 little bit of the editor also, keep in brain that the 32 bit version is fast however, but unstable and the 64 little bit version is slow but steady. When using the 32 little bit version, make sure not to open no more 2 or 3 3 people in one program then, as you shall encounter a storage exception error. To reset the character types opening count, just close completely out the application form and relaunch it simply. The 64 bit version does not have these limitation. If you get an unhandled exception upon loading a save in the energy editing menu, then something went wrong with the save. This is why it is very important to keep a backup of your save. Another option (don't know if it will work but should) is to delete the type in the offending slot machine and create a fresh one in its place, and retry. Do it again launching of the save document is necessary sadly. So fill the save document at the primary menu, on the other hand at every personality selection. To activate the new menu, you will need to select Peach button. I have not tested the "DLC Trophies" without the DLC characters, so it may or might not work properly without the DLC installed. I will leave the old download alone so in the event if people do not want an bloated SSB3DS .net construction version. However they will be passing up on new features.
