An all-in-one solution to your GodMode9 scripting needs!

How to use:

For normal gm9 usage:

  1. Download the GM9Megascript.gm9
  2. Move or copy it to SDMC\gm9\scripts
  3. Run godmode9 on your 3ds and press the home button.
  4. Select scripts, and select the GM9Megascript. For use with PCLess b9s install:
  5. Download the in-files.7z
  6. Open it and extract the gm9 folder to the root of SD card.
  7. Run godmode9 in any possible way you can and execute the GM9Megascript. Or Download and run the GM9Megascript-standalone.firm in any possible way you can.
  8. Choose Hax Options > Install Boot9strap > PC-Less Boot9strap.

What is PC-Less Boot9strap?

Here's a long explanation on what it does.

  1. First, it checks the system if sector0x96 is genuine (usually the check will fail if a9lh is installed in the system). If the check fails, the script will prompt the user if they want to attempt to fix it. Fixing it, the user should have the secret_sector.bin file inside SDMC/gm9/in/boot9strap folder.
  2. Once confirmed that sector0x96 is genuine, it'll then check if the required files are present in the SDMC/gm9/in folder. Here's the branches of the folder that it checks: SDMC
  • gm9
  • ** in
  • ** *** boot9strap
  • ** *** Luma3DS
  • ** *** sdcompiled
  1. If everything is in check, it'll then backup your boot9.bin and boot11.bin.
  2. The script will now install boot9strap.
  3. after boot9strap installation, it'll set up Luma3DS to your CTRNAND.
  4. Now there is a folder named sdcompiled, inside this are all the necessary files we need to have on our sd card after we install boot9strap. Think of this as the finalization proccess on plailect's guide. But since this is a 'PC-Less' installation, this is done purely on the 3ds.
  5. The script will copy all the files from sdcompiled folder to the RAM of the 3DS, then it'll prompt the user to swap the sd card to whichever sd card the user wants to use. Once sd cards are swapped, the script will then move the files from the RAM to the newly inserted sdcard.
  6. After all that, you're done but you'll be given the option to inject FBI to H&S or not before finishing. tl;dr
  • The script installs boot9strap
  • The script sets up the SD Card and ctrnand for CFW use
  • The script injects FBI to H&S (optional)

  • 8bitwonder - got most of the script from his megathread
  • emillois - helping me test and provide info for Old 3/2ds model
  • TurdPooCharger - he's the one who figured out how to inject apps to system apps. Inject FBI to H&S is all him.
