Hello, friend. Did you recently start playing a game using a rom from another region because it got dumped first, but want to transfer it to your main region? Well, look no further! This here is my attempt at writing a guide for those of you who, like me, were confused by the other one found here: http://gbatemp.net/threads/tutorial...v-to-eshop-3ds-3dz-with-savedatafiler.380246/ This guide will walk you step-by-step, but I couldn't have done it without the help of the tutorial creator, liomajor, and the various commenters inside. This guide is made based on the assumption that you have Gateway with a fully functional emuNAND, but it may very well work for other flashcarts/CFW. It's also assuming you are using both .3DS or .3DZ. gamesquest1 detailed how to do this for .cia files, and the different steps you need for it will be listed at the bottom of the guide. Here's what you need: Copy of the ROM that you want to transfer from, and its save. From now on, I will refer to this as ROM1. Copy of the ROM that you want to transfer to, and a save (just start the game and get to the earliest save point possible). From now on, I will refer to this as ROM2. SaveDataFiler. I can't put a link here, so do some of the usual Google-fu. From now on, I will refer to this as SDF. (Optional) A FTP app for your 3DS, which will drastically cut down the time it takes between steps, since you never need to take out your SD card. Alrighty, let's get started! For this tutorial I will use the EU and US versions of Monster Hunter 4 Ultimate as reference, since that's what I used and what a good amount of you readers will use as well. Backup your save games. Seriously, backup your save games. I cannot stress this enough. You're going to need to, anyway. Using the method of your choice, copy your ROM1 save to your SD and rename the .sav to 000400000FF40A00.sav. You can find your save's file name by going to http://3ds.essh.co/, typing in the name of your game in the search bar, and going to the titleid column. For example, my save is from EU MH4U, and its titleid is 0004000000126100, so its save's filename is 0004000000126100.sav. Turn on your console and load up the Gateway browser exploit. Press Select and select ROM1 from your rom list. Open SDF. You should see "CTR Card" followed by a bunch of numbers with broken next to them. Highlight CTR Card, press Y and then A to decrypt and export ROM1's save. It will now show up under the SD tab by a string of numbers which indicate the date, followed by the last several numbers of ROM1's titleid. Turn off your console and open up your SD card. Delete 000400000FF40A00.sav, then copy ROM2's save to your SD card and rename it to 000400000FF40A00.sav Turn on your console and load up the Gateway browser exploit. Press Select and select ROM2 from your rom list. Open SDF. Using the same procedure as step 6, highlight CTR Card, press Y, and then A to decrypt ROM2's save. It will now show up under the SD tab in addition to the decrypted save of ROM1 from step 6. Turn off your console and open up your SD Card. Inside the folder "filer" you will find the subfolder UserSaveData. Inside will be two folders with the same names as the decrypted saves. Backup "filer" onto your PC. This following may be different depending on the game used. Again, I will be referencing MH4U. Open ROM1's subfolder. You will know it's ROM1's subfolder because inside it will have a folder and files with ROM1's titleid. For MH4U, it has the files 00001261.dat, 00001261_.dat, and export.log, with the folder 00001261. Inside the titleid folder are the files system and user1. Again, this may be different depending on the game. Copy the files from ROM1's titleid folder and replace the files from ROM2's titleid folder. Turn on your console, and load up the Gateway Browser exploit. Press Select and select ROM2 from your ROM list. Open SDF, go to the SD tab, select ROM2's decrypted save folder (it'll be the one with the higher number, which indicates it was decrypted later) and press L + A to import the save. It will be stored as 000400000FF40A00.sav. Turn off your console and open up your SD Card (I told you, an FTP client would save you a bunch of time). Rename 000400000FF40A00.sav to ROM2's titleid.sav, which in my case is 0004000000126300.sav. Turn on your console and load up the Gateway browser exploit. Press Select, select ROM2 from your rom list, and start the game. Assuming everything went according to plan, your save from one region is now working for another region. Congratulations! A common problem with this process is CTR Card showing as broken. That means you didn't properly copy whatever save you're trying to import/export from and rename it as 000400000FF40A00.sav. For .cia files, a bunch of steps can be skipped. You don't need to do any save file renaming. Open SDF, go to the middle tab, find the titleids of ROM1 and ROM2, and export/decrypt them. Then open up your SD card, copy ROM1's filer files over ROM2's, and then go back to SDF and import ROM2's save. If the files in your decrypted save folders are different from mine, then steps 14 and 15 will be different. I can't imagine them being too different, though. Got another problem? Let me know and I'll try to help.
