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).

Animal Crossing wild world is not working. I am using USA 1.1. I get a white screen. Does it take a while to load or hm?

I think the latest version of luma broke something. MKDS online bypass code now results in a crash.

Hello everyone, made an account specifically so I could contribute this little bit of information:

I recently hacked my New 3DS XL SNES Edition with custom firmware, ntrboothax, Luma3DS, etc. etc., and instlaled Nitrohax. I had a few problems getting it to work, namely it will *not* load any .xml that isn't specifically named "cheats.xml", but after using the Fast Text, All Hits Are Criticals, and Stornway Armor Shop Stocks DQVC Items codes, I can confirm Nitrohax 0.99 works with Dragon Quest IX.

 

[Beerus]

thanks

 

[DwarfWarden]

Not to spam the thread but I used a lot of different codes in Dragon Quest V, so I can confirm that game's working with Nitrohax 0.99.

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

You need to be using Luma 6.0.1-DEV (I recommend the Hourly DEV version)
It now works on Luma-NORMAL, To get it, Update to Luma Hourly or wait for Release 6.0.2+
If you use Luma-NORMAL, Make sure to put twlBg.cxi in sd:/luma/ (NOT SysModules)
Yet again another big change! You no longer need to patch twlBg.cxi manually!
Hooray!

Yet ANOTHER big change!, You no longer need a patched twlBg.cxi, Update to the latest Luma and NitroHax and you will no longer need it to be patched!

Part I (Updating Luma)
1) Download the latest version of Luma3DSUpdater;
2) Open Luma3DSUpdater and update your Luma to the latest version (6.1.2 or newer required);
3) Power off your 3DS;

Part II (Turning on twlBg patches)
1) Hold select while Powering On your 3DS;
2) Select "Enable experimental TwlBg patches";
3) Press Start to save Configuration;
To be able to play games normally that dont work with Nitro, You MUST disable this to play it, Even when booting normally.

Part III (Getting cheats!)
1) Download the `cheats.xml` file from the Download Center; (Region doesn't matter)
2) Download and Open `R4CCE` (Revolution 4 Cheat Code Editor);
3) `File` -> `Open` -> `Downloaded cheats.xml`.
4) Remove all games you don't have and/or don't plan on getting as the final cheats.xml file MUST be under 2,500kb (2.5mb) or it can't load!
5) Once you have the cheats.xml and its under 2.5mb, Put it on the root of your 3DS SD Card.
Done! If any game/cheat is missing just click `Add Game` or `Add Cheat`.

Now you can enjoy using cheats!
