NitroHax3DS is a tool to apply cheat codes to NTR (NDS) games on the 3DS. This tutorial guides you on how to install, add cheats, and how to deal with the 2,500kb (2.5mb) cheats.xml file size limit. This tutorial does not show you the general usage of NitroHax, as the homebrew GUI generally takes care of that for you.

Requirements

• A 3DS with Luma 6.1.2 or newer using boot9strap is the recommended setup for your 3DS and for any homebrew.
  If you are still on arm9loaderhax, pasta cfw, or anything alike, then try updating your hacks to boot9strap.
• NitroHax3DS 0.99.NTR (Final ver?) CIA file, Do not use the DSi release downloads.
• FBI 2.6.1 (Final) for installing NitroHax3DS CIA file.
• Revolution 4 Cheat Code Editor (R4CCE) for managing the cheats.xml cheats and therefore the file size.
• An Action Replay XML file (cheats.xml), e.g., DeadSkullzJr Repo (right click -> save link as), CodeJunkies EU, CodeJunkies US

NitroHax3DS Installation and Usage

Please follow the instructions on the NitroHax3DS readme for general Installation and Usage Instructions.

Lowering the cheats.xml file size

While NitroHax3DS has no actual cheats.xml file size limit, it should NOT exceed 2.5MB, nor should it really even get close to that size. NitroHax3DS loads the cheats.xml to RAM and the 3DS only has 4MB of RAM. This means you would potentially run out of ram, or leave too little amount of RAM available for the game or system to work sufficiently.

To be on the safe side I recommend lowering the cheats.xml file size to be less than 1.5MB in size. The lower it is, the better. You should only have cheat codes for games you want to use, and only have cheat codes you plan to actually use. White screens and crashes may be caused by the cheats.xml being too large (even if it's around 1.5MB).

1. Open R4CCE, click `File` -> `Open` -> And open the cheats.xml file.
2. Remove all cheats for games you do not have and/or want to use, the more you can remove the better.
3. Once you have the cheats.xml lowered as much as you can, Put it on the root of your 3DS SD Card.

F.A.Q

Q: I get a white screen when booting from Nitro but not when I boot normally;
A: The game may be unsupported, or the cheat code may be incompatible with your specific ROM region.

Q: I'm encountering a problem that happens even if I disable all cheats, yet doesn't happen if I play without NitroHax3DS;
A: It might be a NitroHax3DS problem. If you feel strongly that it could be a NitroHax3DS bug, report it on the GitHub Issues page and not here.

Q: Do DSi Enhanced Games work? What about DSi Exclusive Games?
A: No! [source] Sadly DSi Enhanced Games are not supported! This is due to NitroHax using an incredibly outdated Cart loader code that is not compatible with TWL game cartridges. This means both DSi Enhanced and DSi Exclusive games are not supported. E.g., Pokemon SoulSilver/HeartGold (DSi Enhanced), and Face Training (DSi Exclusive).

Got a question not here? Post it below.

Then its not supported I think

 

[PRAGMA]

I'm on the latest luma3ds dev version 6.0.1-DEV
The twlBg.cxi is 1,263 kb or 1.23mb and is located in luma/sysmodules on my microsd card on my new Nintendo 3ds.
Nitrohax boots and my game cart of golden sun dark dawn is not inserted until the message to insert it appears.
I insert it and press start, the cheats show up and I check one of them and then click start game.
And my game is stuck on a white screen and does not boot.
but I know nitrohax works since it booted my copy of Mario kart ds.

Its possible that the cheat is causing it, Have you tried to boot the game with no cheats selected and also tried to normally boot up the game?
If it still does the white screen and boots up fine if you load it normally then its not a supported game :/

The game boots fine from home menu.
In nitrohax trying to boot with or without cheats still lead to a white screen with the multicolored dots on the bottom screen.

You need to install DevkitPro and Python - Make sure you add it to Path in installation settings - Look at the OP to see an image showing where to enable it;
You MUST restart your PC after installing Python with the Path;

Which game is it? Seems to be unsupported with Nitrohax unfortunately D:

Uninstall Python and open the Installer again (Dont use "Repair" it only "fixes" features installed it doesnt let you add new ones)

golden sun dark dawn

Ok, Its unsupported unfortuanetely :/ You did all steps correctly
You could try one last thing, Theres a new update to NitroHax (0.93) - Download it from the OP and try using it, You never know it might fix it;

 

[WarioTails358]

Just tried, does not work.
Guess I'll have to wait for a fix/update unfortunately.

A LOT of people seem to have issue's using this script and/or NitroHax for very simple reasons, I'm here to stop you from wasting an hour trying to get around bugs

Download Centre
NitroHax (duh)
TWL_Firm_Patcher
Python2
Devkitpro
Decrypt9WIP.zip
Action Replay DSi Code Manager

You need to be using Luma 6.0.1-DEV (I recommend the Hourly DEV version)
Re-download Nitro! It is now v0.93 and you no longer need to take out the game card before booting Nitro!

Part I (Setup the Environment)
1) Install Python - Make sure you add Python to Path (Click here to see where to enable it);
2) Install DevkitPro, No special steps needed just spam Next;
3) Restart your PC - MUST! Otherwise you will get a "python" command was not found error;

Part II (Getting the un-patched TWL_FIRM.bin)
1) Open Decrypt9WIP.zip and rename `Decrypt9WIP.bin` to `x_Decrypt9.bin` and move it into `sd:/luma/payloads`;
2) Turn off your 3DS and Hold X while turning it on, You are now in Decrypt9, Go to "SysNAND Options" -> "Miscellaneous..." -> "NCCH FIRMs Dump". Wait for it to finish, Ignore the few "Failed!" messages, As long as it says Success in Green at the end you are good to go;

Part III (Patching the TWL_FIRM.bin)
1) Extract `TWL_Firm_Patcher-master.zip` to the Desktop;
2) Rename `TWL_FIRM_O/N3DS_{x}.bin` to `firmware_twl.bin` and Copy/Move `firmware_twl.bin` to `TWL_Firm_Patcher/input` finally remove the random file already in there;
3) Go back out and open `go_o3DS.bat` or `go_n3DS.bat` depending on your system;
4) It will show a bunch of text and you will see it ask you to `Press any button to continue...`, You need to do this 2 times and it will be finished and the .cxi is in the Patcher folder's root;
5) If the .cxi is roughly `1,200kb's` the .cxi was created successfully, You can now place it in `sd:/luma/sysmodules` and delete all NCCH files (AGB_FIRM, TWL_FIRM) from the SD card's root;

Part IV (Using NitroHax)
1) Install NitroHax.cia using FBI;
2) Now we need cheats, Install Action Replay DSi Code Manager, Open it and click "Reload" in the Subscriptions tab; Now right click the CodeJunkies region you wish to use -> Copy -> Paste it into "My CodeList's" Section, Right click it -> Rename -> "cheats". Now copy the "cheats.xml" file located in, Documents -> "Datel" -> "Action Replay DSi Code Manager" -> "local_codelists". Now put it in the root of your SD card.
2) Boot NitroHax with no game card inserted! You can now boot Nitro with the card inserted!
3) Once you are in Nitro it will load the Cheats, Not all game's are compatible with NitroHax, Look below to see if your game is Confirmed Supported, If it isn't listed you can test for us - Dont enable any Cheats, Click "Start" and load the Save file. If everything went well post below that "x" game is confirmed working and ill add it to the list;

Now you can enjoy using cheats!

[cearp]

I could be wrong but if its a .cia installed DSiWare doesn't NTRBoot support cheat plugins for them?
