Switching from Gateway to CFW can be a pain, especially since all your saves were created on Gateway. There's only one way to get those saves to be usable on cia games, and that's to decrypt the saves and eventually import them in the end. It's a very tedious process, but worth it in the end to be able to keep all your saves you worked hard on for so long. Gateway has become more and more obsolete, with CFW being more convenient to work with. ESPECIALLY Arm9loaderhax! This will guide you on how to convert Gateway saves, and import them into cia games. For those who want to abandon Gateway, or those who still want to keep Gateway but use CFW. No other guide for this existed so I figured I had to create one. Be sure you have PLENTY of time to work on this, you'll also need a ton of patience for this! Thanks to @zhdarkstar for the tip about using JK Save Manager for just about everything! Made the guide ten times easier than it was before. Requirements JK Save Manager CTRXplorer (Can also use FBI) I. Preperation Steps 1.

Make a new folder and name it to whatever game it is Example: SD:/Gateway saves/Super Mario 3D Land/ 7. Place the 0004000002C23200 sav file in this new folder you just created 8.

PLEASE make a backup of ALL the backed up saves from JK Save Manager, by uploading them to Google Drive or Dropbox!! This way your saves are forever safe! About Card2 games Certain games are card2 type games, where the save file is stored inside the cartridge. In our case, the save is stored inside the rom itself. Games like Pokemon XY/ORAS, Animal Crossing New Leaf, Tomodachi Life, Zelda Tri Force Heroes are card2 games. They don't produce a .sav file on the SD card like card1 games. To export card2 saves, carry on by selecting the rom then using JK Save Manager to export the cartridge's save. Then import the save in SD/Cia. Trivia - Gateway saves are encrypted, so you can't export the save until you first renamed it to 0004000002C23200 and place it on the root. Since you can't have more than one of the same file name in one directory, you gotta work on these one by one. In this process, you're decrypting the saves. - Some games like Fantasy Life and Theatrhythm Final Fantasy store their primary save data in "Extdata". If you plan on using the same NAND in the end, you don't have to worry about exporting/importing that. - Saves from JK Save Manager, can be used by just about ANYBODY, from any region. They're highly universal and valuable to share on saves threads. Post them if you like to contribute!
