How to Manualy Use a Backed Up Save for Cfw 3ds

This tutorial will teach you how to backup Nintendo DS save games from original game cartridges using an Nintendo 3DS. Using an Nintendo 3DS to backup Nintendo DS games is a lot easier than using an actual Nintendo DS.
You do not need to mess about with legacy WEP secured wireless networks, Firewalls, FTP's servers and GBA / DS flashcards. This is a simple offline solution anyone with a 3DS running the Homebrew Launcher or a Custom Firmware can use to backup Nintendo DS save games from original game cartridges in a matter of seconds.

Requirements:

You will either need a Nintendo 3DS running custom frimware or the Homebrew channel to follow this tutorial.

1. Getting started backing up your Nintendo DS game with the Nintendo 3DS:

First you need to download TWLSaveTool, this is the app we will use on the Nintendo 3DS for DS save game backup and restore.

If you have a 3DS running custom firmware you can use the CIA version.

If you have a 3DS which only has the Homebrew Launcher you require the 3DSX version. Please note the 3dsx version requires you to have either PokéTransporter or Pokémon Dream Radar installed on your 3DS. In both cases you'll need to pay to be able to download them from the Nintendo Eshop.

2. Installing TWLSaveTool:
To install the CIA version:Simply copy the TWLSaveTool.cia to the Nintendo 3DS sd card then install using your favorite CIA manager, I personally use BigBlueBox.

To install the 3DS version:

Simply copy the TWLSaveTool folder to your SD Card > 3ds folder

3. Backing Up Nintendo DS save games:This is the easy bit, either load TWLSaveTool from the 3DS home screen if your using Custom Firmware:

Or from the Homebrew Launcher depedning on which version of TWLSaveTool you installed:

TWLSaveTool should display the DS game currently in your 3DS:

You can then press:
B - To backup the Nintendo DS save
A - To restore the Nintendo DS save
X - To erase the Nintendo DS save from the game cartridge
Start - exit the app
Y - To re start the app and backup / restore from a different game cartridge
Left / Right - allow you to change the file name of the savegame you are backing up (adds a number to the end of the save)

Backed up save games will be on the 3DS's SD Card inside the TWLSaveTool folder:

If you downloaded a save game from the internet you wish to restore to your original NDS cartridge simply name it what TWLSaveTool identifies the game title is, then add a number at the end.

For example POKEMON W .0 .sav Red = Game title as displayed in TWLSaveTool
Blue = File name, can just be .0 if you dont have any other saves for that game on the 3DS's SD card.
Green = File extension should be .sav

Congratulations you can now backup / restore Nintendo DS games in less than 20 seconds!

I got this Error with Pokémon White 2/ Black 2 and Heart Gold :c
Do you have save data present on your cart? I think I remember this causing issues with other save backup/restore utilities in the past so maybe this could be a factor here.
Otherwise what are you using to run this? and, if applicable, which CFW/version?

I use homebrew with Freakyhax. I also have the Savemanger for Ultra Sun on the card
Do you have Pokémon Dream Radar or Poké Transporter installed? You need to have either of those for it to work (says so in the first post.)
If you have them, make sure TWLSaveTool.xml is properly present in TWLSaveTool folder.

No my Error is 143 not 142
That's not the error code. That's the line at which the error occured.
That was from version 1.0, you're using version 1.1. Code has been added/moved around/etc so the line at which the error occurs may change.

Anything you have migrated from Gen 1 to 3 is not legit, just so you know. You can go from Gen 1 to 7 on the 3DS however thanks to the Virtual Console games on the 3DS.
First you want to hack your 3DS, If you follow this tutorial from start to finish: https://3ds.hacks.guide/ you will have a fully hacked 3ds capable of following my above guide.
The above guide also has a section about uninstalling hacks / cfw: https://3ds.hacks.guide/uninstall-cfw that is not something i've ever done however. I just be careful online and only play my legit games and never use homebrew apps when the 3ds is connected to the internet, theirs obviously some risk there though.

Once you have a hacked 3DS you can follow this guide here: Pokemon GameBoy / Rom Save Transfer To 3DS for Gen 1 and 2.

You can even play GBA Games on your 3DS if you decide to keep hacks, meaning you can create your own GBA Pokemon games for use on the 3DS: Nintendo 3DS GBA Game Injection

To write any emulator saves from the Gen 4-5 DS games to real cartridges, your looking at the correct tutorial. Simply scroll to the top of this page and follow my tutorial.

Hopefully that gets you started anyway

I think you will enjoy your 3DS for Pokemon as with hacks it's capable of playing all the core games from Gen 1 to 7.

If you want to do this legit on real hardware your going to need 2x DS or 3DS consoles to transfer from Platinum to Black 2, it doesn't really matter which, it can be a DS and 3DS or 2x DS consoles or 2x 3DS consoles.
Your also going to need a legit Platinum DS game and a legit Black 2 DS game.

You would restore your Platinum save game to the Platinum cartridge and the Black 2 save to the Black 2 cartridge (or start a game and finish it on the Black 2 cartridge)

When you finish the Gen 5 games you unlock the Poke Transfer Lab on Route 15. When you visit that your Black 2 game will send a program via the DS download play application, on your other DS with your Platinum game in you will select download play on the homescreen to load the transfer app. This allows Pokemon to transfer from Gen 4 to Gen 5 over Wireless using 2x consoles.

You don't need to hack your DS games, save edit or anything, you simply need to restore the save games to your DS game cartridges. The only thing you need any sort of hacks for is to have an easy way of getting your emulator saves on to the DS game cartridges. I personally think using hacked 3DS is the most easy way of doing this in 2018 although other ways do exist.

I get a black screen with TWLSaveTool 1.1 by TuxSH at the top and nothing else. I have heartgold in the gameboy. I have to restart to leave the screen.
Anyone seen this?
What custom firmware do you have on your 3DS? I also presume Pokemon HeartGold and other DS games play on the 3DS as normal?

Homebrew(through Steelhax), and Save Manager (for 3ds games). The nintendo update is 11.8.
UPDATE: I think it is because unfortunately my heartgold is a bootleg copy (damn you ebay!), cause fire emblem, it worked fine.

Is there a way to download PokeTransporter or DreamRadar on a 3ds without updating the software ??
I have Ver. 11.1.0-34E and I enter homebrew with Pokemon AlphaSaphire
If you have CFW installed you can install the CIA, however based on what you have said not without updating.
