Nintendo 3DS GodMode9 Method

[todo: add ntrboothax tutorial and other methods of loading bare-metal ARM9 software]

Tools

  • A Nintendo (New) {2/3}DS with a method to run "bare-metal" ARM9 software. Methods include having a custom firmware installed or a DS flashcart with ntrboothax.
  • GodMode9 (Ensure you are using the latest so you can notate the gamecart ID.)

Dumping

  • Run GodMode9
  • Copy down the ID in brackets to the side of GAMECART (if it's not there, navigate into GAMECART then return back to the main menu)
  • Navigate into "GAMECART"
  • Copy the .3ds file [b]without the .trim[/b] to the SD card. If split files show up (for 3DS games that are >=4GB), you will need to copy those.
  • If you copied the ROM in split form, you need to combine them using copy /b part1 + part2 combined on the Windows command line or cat part1 part1 > combined on the Mac OS or Linux terminal. Otherwise, you're done.

Gathering Dump Info

  • Dumping Tool: The name and version of the tool/method use to make the dump.
  • CRC32: Generated from the ROM file using HxD, for example.
  • MD5: Ditto.
  • SHA-1: Ditto.
  • Game title: If it differs between different places (e.g. title screen, console menu banner, box, cart) then go with the one on the front of the box.
  • Region: The region the disc originated from like USA, Japan or Europe
  • ROM Revision: The revision found in the ROM data.
  • ROM Serial: The 10-character serial found at 0x1150 the ROM data, in the format "XXX-X-XXXX" with X being a letter or number.
  • Languages/Language Select: Some games either show a language selection screen at startup or in the game options. Many games will boot with different languages depending on the active language selected in the BIOS. Booting the game with each language selected in the bios is necessary to identify the supported languages for these games. Note that it is possible to submit a game without checking the languages, but this then needs to be stated in your submission.
    • Tip: Using an emulator like Citra can speed up the language checking dramatically since you can switch the system language in the emulator settings much faster than on a real 3DS.
  • Cart Serial: It is located on the label on the front of the cart the form of "LNA-CTR-AREP-EUR" (where X is a letter or number), also it may have a number (Like -1 or -2) appended.
  • Cart Additional Serial: On back of cart.
  • Box Barcode: The number on the case displayed beneath the vertical lines, see Barcode.
  • Box Serials: The serials on the case. Example: CTR P AREP, TSA-CTR-AREP-UKV, Art.-Nr.:2221246T
  • Size: The size of the ROM in bytes.
  • Chip(s) serial(s) (optional): The codes on the ROM chip inside the cart. You would need to break open the cart to see these.
  • Scans: The following scans (or photos) would be good to have: Front and back of the following items - box, cart and PCB.
