Note: You can use any controller, but this tutorial will only describe the steps to do it with a gamecube controller + official gamecube controller adapter. Anyway, only the first step is related with the controller. The other steps are the same for every controller.

Special thanks to Stary2001 and @KazoWAR for this awesome tool.

Requirements:

• A 3DS with CFW and a CIA installer
• Homebrew Launcher (latest version) or NTR CFW
• InputRedirection
  • for NTR (https://github.com/Kazo/InputRedirection/releases/tag/NTR-build)
  • for Homebrew Launcher (https://github.com/Kazo/InputRedirection/releases/tag/master-build)
• InputRedirection PC Client
  • for NTR (https://github.com/Kazo/InputRedirectionClient/releases/tag/NTR-build)
  • for Homebrew Launcher (https://github.com/Kazo/InputRedirectionClient/releases/tag/master-build)
• A PC with Windows
• A Gamecube controller
• Official gamecube controller adapter
• Wii U USB GCN Driver (http://m4sv.com/page/wii-u-gcn-usb-driver)
• XPadder (http://xpadder.com/) or a freeware alternative

Recomended:

• Wireless Network Watcher (http://www.nirsoft.net/utils/wireless_network_watcher.html)

Steps:
1. Install the driver of the Official gamecube controller adapter in your pc (there's a lot of tutorials on the internet, so please google) and run it.
2. Configure Xpadder (It's pretty easy with a noob-proof GUI). Remember the keys you choose for each button.

Now you have to choose an option

NTR CFW (recommended - better compatibility )
3. In your 3DS install InputRedirectionNTR.cia.
4. Run NTR CFW, press X+Y and select "Enable Debugger"
5. Run the installed CIA.

Homebrew Launcher (not recommended - worse compatibility)
3. In your 3DS install InputProc.cia and put the 3ds folder in the root of your sd card In
4. Run The Homebrew Launcher and launch input_loader.
5. Press start and then x to return to the home menu


6. Now in your PC, go to the PC Client and open InputRedirection NTR.exe (InputRedirection .exe if you chose the HBL option)
7. Press F1 to set your 3DS IP address (use wireless network watcher or ftpbrony to know it) and then ESC
8. Press F2 to set the key for each button of your 3ds (you can use Xpadder to remember what keys you used for the gamecube controller). To do it, first you have to press the pre-selected key, and then press the new key for each button. Once you're ready press ESC.
9. Test the controls (also, you can press F4 to show debug information).
10. Enjoy

I wish there were something like this for the DS.

If anyone's interested by the c-stick feature you should definitly check this guide out: http://forums.mcleodgaming.com/viewtopic.php?f=4&t=42982
It's not perfect (you can get stuck, you'll see) so we can maybe find a better way to do it with xpadder advanced functions

You just answered your question. The reboot closes NTR.

so if we wanted it to work with smash on old 3ds we would have to make it load when the cfw loads which means making it part of the cfw

Yup but is it too hard for you to launch the NTRboot everytime you want to plug your gamecube pad?

Does someone know why my Router blocks the connection between my N3DS and PC?

Ignore him.
Besides which you missed the point. Smash does a firmlaunch, which kills NTR.

well it doesn't work if I don't boot it and works if I do..

Thanks alot OP. I can finally play those circlepad games without having my finger slip over and over on the N3DSXL.

Xpadder requires payment to download it. Unless there's a free option I haven't found.

Xpadder doesn't have DRM. A terrible thing to say, but it's around. Well worth the donation as well.

Ooh gonna look into this now.

Is there a setting we can do to make it to where you can both walk and run w/t he analog stick? Right now I can only run

 

[Februarysn0w]

Finally this works!
Thank you very much.


I do not know why, but with pokemon game doesn't work.

My environment
PC:/
Windows 10 Pro 64bit
Xpadder
official GameCube adapter
GameCube Controller

3DS:/
New 3DS 11.0(J)
Corbenik CFW
NTR 3.4

 

[duffmmann]

If you're using this for Sm4sh, you may as well play the Wii U copy, since you're tethered to a PC anyway. That or Dolphin and a copy of Project M 3.6, or better yet, Smash Bros. Legacy or Legacy XP, when it releases.

Unless of course you want to play Smash Run.

mm the stick is too sensitive, I haven't noticed that, no idea how to fix it tho.

 

[cvskid]

Has anyone tried this on a O3DS with an xbox 360 wired controller and also played online to see if the input delay from this program plus the input delay from online is bad?

 

[Intronaut]

Finally this works!
Thank you very much.

It's a known-issue. An user said it can be solved connecting to internet inside the game.

I played brawl competitively so walking is huge for me lol

 

[CitizenSnips]

Could i possibly emulate the circle pad pro with this on a old 3ds? I'm using a ps4 controller right now and everything works fine but i want to use the right analog as a cirle pad pro

 

[Selim873]

Got around to using this seeing the NTR version came out. This is pretty awesome!! Do you have plans to update to add analog support? The touch screen support was a nice touch! (Press F4 to go to debug and you click on the screen with your mouse being a red dot.)
