What is homebrew?

Homebrew applications are custom, user-made software, which haven’t been authorised by Nintendo. This can include save editing tools, games, emulators, and more.

Homebrew can be run for free on any DSi system, regardless of firmware version or region.

What does this guide install?

This guide will install HiyaCFW, a custom firmware for the DSi, and/or TWiLight Menu++, a homebrew home menu replacement. TWiLight Menu++ and HiyaCFW can both be set up on any console on any version.

Custom firmware enables you to use more advanced hacks that userland homebrew can’t easily do. For instance, signature patches let you install unsigned titles that appear right on your System Menu.

TWiLight Menu++ is a homebrew that functions as a complete home menu replacement with many additional features such as rom loading and custom themes.

What should I know before starting?

  • Homebrew allows you to modify your system, which could easily result in a brick if done improperly
  • Keep your console plugged in at all times during this process to avoid sudden power loss
  • You will need an SD card to use this guide
    • Your console should come with one

Which method should I use?

There are currently two methods of running homebrew, and therefore running custom firmware:

  • Memory Pit, a DSi Camera exploit for all retail systems, firmware versions, and regions
  • Flipnote Lenny, a firmware-agnostic Flipnote exploit that can’t be used unless you already have it due to DSi Shop closure

Memory Pit is the easiest and most widely available exploit to set up, and is the default method of this guide. Continue to Installing Unlaunch

However, if for whatever reason you have a functional copy of Flipnote Studio and prefer use it instead of DSi Camera, you may proceed with Flipnote Lenny. Continue to Installing Unlaunch (Flipnote)
