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).

Phantom Hourglass works but (at least for me) only when card is inserted after nitrohax has started. Pokemon ranger works fine.

Well if you guys read the Bottom of the OP you would have your answer.

Thank you for posting the code XMLs! They work great!

No problem - Make sure they are below 2.5mb's

I just tested Need for Speed Carbon own the city (I think thats its name xD) and it kinda works. It works perfectly fine Without any codes enabled, but gets stuck on the ea Splash screen if you enable any code.
But i dont know if its just the codes i tested with.

Edit: I got it working. I Completly forgot that you can but the game in before you launch Nitro Hax.
So it wirks if the Cardridge is inserted first or it just doesent work any time you try on this game.

New Super Mario Bros didnt work for me; it might be because i used a fuckload of cheats though.

Its confirmed to work, You must have used too many cheats at once causing it to crash.

Pokémon HG doesn't load, blackscreen when loading save.

Hello, I did everything right. Created the .cxi file 1,263 KB and I put it on the sd:/luma/ folder. Then, when I try to install Nitrohax CIA it doesn't install. I mean, it says that it was installed correctly, but it doesn't appear on the home menu. What am I doing wrong? It's the first time that a "successful" install is unsuccessful, and it's not that I don't know how to install CIAs but maybe I'm doing something wrong in the process.

EDIT: Yeah I got it installed just by rebooting, thanks @ShinyMK ! The only problem is that whenever I load my Pokemon Platinum cartridge, it just loads blank on the upper screen. The bottom just has some color points, and it just freezes there.

EDIT2: It worked on Platinum! But, I think there might be something wrong with my cartridge reader, it has problems reading NDS cartridges :/, althought the nitrohax recognized them pretty fast. I mean, problems recognizing the cartridges on the home menu, but not on the nitrohax menu.

After installing, You just reboot the system.

Just curious, is there any way to do the first part (getting the cxi) on Linux?

Not that I know of no, Just google TwlBg.cxi on google and click the 2nd link

PKMN HG/SS/B&W(2) can't be booted because of the implemented IR Chip in the cartridge board.
Kinda similar situation like back in the days with woodumper, but the author manged to make a workaround

You no longer need to patch TwlBg.cxi manually
I recommend everyone who used this tutorial to remove the TwlBg.cxi from sd:/luma/ and re-do the tutorial
Its quick this time

did you try HG again? Just kidding

If you mean HeartGold, This wont make a difference. Its basically just saving you from manually making the TwlBg.cxi
