How to install HomemenuHax on O3DS and N3DS Notes: This method cannot currently run all homebrew. You need to already have a way of entry into homebrew for this.THIS WILL NOT WORK WITH CUSTOM THEMES. I didn't make this app. If you want the inverse of this (like auto booting to HBM), look here. (The inverse is by Steveice.) This is my first tutorial Okay, so to start off, we need to download the boot.3dsx file; this is the file used for the homebrew menu. You may choose to use the default boot file, found here, or a modified boot file like the homebrew launcher with the grid layout. Put this on the root of your SD card. (This should already be there if you have used homebrew before.) Next, we want to download this homebrew app. This is what will trigger the exploit upon startup if certain conditions are made. In this case, it is if the L button is pressed at startup. Put that folder after extraction into the 3DS folder. Now run the App from the 3DS homebrew exploit of your choice and then follow the on screen instructions from there. Now when you boot up your 3DS, press and hold L and the system should run the exploit!
