This document provides a complete overview on how to hardmod your Nintendo DSi to run homebrew code using a bootrom exploit.
This guide is not aimed at total beginners. If you only want to run custom software on your DSi, I suggest you try this guide first.
Important
READ THIS GUIDE ALL THE WAY THROUGH BEFORE ATTEMPTING ANYTHING.
Note
As everything is still very much a work in progress, the installation procedure is far from being the smoothest possible. Sorry about that.
- Your DSi freezes, crashes, or shows an error screen on boot, but you still want to play games on it.
- The eMMC NAND of your DSi is corrupted, but you still want to play games on your console.
- Your DSi can't be modded using the Memory Pit, Stylehax or Flipnote Lenny exploits.
- You don't want to use Unlaunch, but still want a cold boot exploit.
- You want to dump the full, unredacted DSi boot ROMs, or want to play around with the DSi hardware at a very early boot stage.
- One of the pre-existing exploits (Memory Pit, Stylehax, Flipnote Lenny, Unlaunch) or a flashcart suit all your needs.
- You don't want to hardmod your DSi.
- You can't solder --- hardmodding your DSi means you will have to solder.
Throughout this guide, you will need to:
- Solder surface-mount components. Installing the modchip will require handling tiny SMT components. If you have never soldered using flux and tweezers, please do not attempt to install this modchip.
- Compile software from source on your computer. This means you will need to have a development environment installed.
Tip
Once the software is stable, binary releases will be provided so this second requirement can be relaxed.
