How to play online, and the importance of a private header. (noob private header questions answered)

What is a private header?
A private header is the header extracted from a retail cartridge nobody else has.
But...
What most people are referring to when the say "private header" Is a 16 byte string of characters, The Unique Cartridge ID​

Why Do I Need One?
To avoid being banned of course..​

Where / How Do I Get One?

1. Gateway Launcher

The gateway launcher can be run on ANY 2DS / 3DS / 3DSXL / N3DS*/ N3DS XL* as long as it is 9.2.0 or lower. The gateway cart is not needed.
* "New" 3DS consoles require Cubic Ninja or OOT.
* Internet browser is required on O3DS consoles.​

1. Place latest launcher.dat on the SD
2. Launch gateway
2a. On 3DS / 2DS consoles, visit go.gateway-3ds.com
2b. N3DS consoles require Cubic Ninja, Just scan the QR for your region included in the gateway download, Or OOT with the savegame exploit installed​
3. Make sure the cartridge you want the header from is inserted in the 3DS
4. Select the "Dump Cartridge" option in the gateway menu
5. Insert the 3DS's SD into your computer
6. Copy the .3ds file from your SD to your PC
7. Open the rom with Gateway Rom Patcher
8. Click "Export header to file" and save it.

2. PowerSaves 3DS

This is the most expensive option, it's best used if you don't have a GW compatible console or a friend with one.. Best for if you already own the PowerSaves device
Anyway, follow my tutorial here:

3. Buy One

Finding someone to buy one from is up to you.​


Bans

If you haven't heard, nintendo has started banning pirates.
These two lovely posts should summarize it:

Okay, I have my header.. How do I use it?

The method of use varies depending on what flashcart you have​
  • Gateway 3DS
To Patch a rom for use with gateway, we will need Gateway Rom Patcher, By PsyKo
1. Open rom file with GW rom patcher (obviously)
2. Click "Import Header From File" and select your header .bin file
3. If the program suggests a better chip value, click yes. Then be sure to click apply to apply it.
4. Your header should be patched now, and your rom safe to use with your gateway​

  • Sky3DS (and clones)
The tool we'll be using: No Ban No Sky, By hackotedelaplaqu
1. Open No Ban No Sky, and select the latest template file
2. Select your header .bin file
3. Press the "Patch all games in template file" button
4. Write the games to your micro SD using diskwriter and the template you patched​


Error 002-0123

Error 002-0123 happens when either Unique ID, or the chip manufacturer is invalid.
Discussion about error 002-0123

How to fix it: (SKY3DS Method)
We'll be using Sky Army Knife, by Foxi4
1. Open Sky Army Knife
2. Select latest template file
3. Select the rom that is giving you the error
4. In the "Cart ID" section, change the manufacturer
5. Click "Save to .txt"
6. Open diskwriter, and select our modified template
7. Delete rom from your SD with diskwriter
8. Re-write the rom with the edited template we made
9. Cycle through the games on your sky3ds so that it refreshes
10. Play Game

(If you still get the error, Repeat steps 4 to 9 but change the manufacturer to something DIFFERENT)​

How to fix it: (Gateway 3DS Method)

1. Open your rom in GW rom patcher
2. Click the blue lettering in "Enter a new chip ID or auto-detect it"
3. In the "manufacturer" drop down box, select one
4. Click apply
5. Copy rom to micro SD and try game

(If you still get the error, repeat steps 3-5... but use a different manufacturer than last time)​

F.A.Q.

Q. Do I need a different private header for each game?
A. No, you can use one header to patch all of your games.​
Q. Can I use the header from an offline game?
A. Yes, you are able to use the header from any game, wether it is online capable or not.​
Q. Can I Still Be Banned?
A. The only true way to avoid a ban is to pay for your games, but we both know that's not going to happen.​
Q. Can me and someone else share a header?
A. No.​

Jaggent360, His support thread gave me the idea for this one. (He asked for a "little credit", so i used the smallest font.)
