-The following method work on all models of the 3DS, 2DS and New 3DS handhelds.+Follow the [[https://3ds.hacks.guide/|3DS Hacks Guide]] to enable running homebrew on your 3DS and install the latest stable version of [[https://github.com/d0k3/GodMode9/releases|GodMode9]].
  
-Follow the instructions over at [[https://3ds.hacks.guide/|3DS Hacks Guide]] for more details on how to get your handheld ready, by enabling it to run 3DS-mode bare metal ARM9 homebrew, and make sure the latest stable [[https://github.com/d0k3/GodMode9/releases|GodMode9]] is installed/present (v2.0.0 or later). +You do not necessarily need to install custom firmware to run GodMode9 - you can stop following the 3DS Hacks Guide once you get to the point of being able to run a .firm file (or equivalent file for that particular exploit). But for convenience, you may want to follow the 3DS Hacks Guide to the end, so you can easily run GodMode9 at boot.

-  * General Note: If you are submitting this info to a person/group in order for them to add it to a database, you can skip the transcription of some things, and leave it to them. But it can make the process smoother if you do the transcription yourself. +
-  * Link(s): Link to release post/page, if applicable. +
-  * Decrypted ROM file info: To encrypt a copy of the ROM in order to get the encrypted hashes, use [[https://github.com/SabreTools/NDecrypt|NDecrypt]],  [[https://archive.org/details/3dsEncryptV4|3ds_encrypt_v4.py]] or GodMode9 itself (use "NCSD image options">"Decrypt file" on the copy) +

-  * Revision. You can find this at 0x312 in the ROM. +
-  * Cart Images: Back and front. +
-  * Cart ID: Get this from the .txt file provided by GodMode9 +
-    * Technical note - GodMode9 displays these in the little endian byte order (i.e. first byte is the chip manufacture byte), which makes sense as the 3DS CPU is little endian (as are the DS and DSi's CPUs). But the gbatek documentation of the [[https://problemkaputt.de/gbatek.htm#dscartridgeprotocol|cart protocol]] displays these in big endian byte order (i.e. last byte is the chip manufacture byte). +
-  * Box Barcode: Keep the spacesIt should be verified against the barcode itself by using barcode scanning software and using the check digit. +
-  * PCB Serial: Use for ''▼'' for the triangle character, one space character ('' '') for each empty "slot" and ''•'' for the small circle characters (which don't always appear). +
