Note: This page is about the firmware M3 Sakura. If you were looking for the flashcart, go to M3i Zero
M3 Sakura is a loader for the M3 DS Real and M3i Zero flashcarts. It was developed by MoonLight, the creator of Moonshell. It was officially released on 30 May 2008 in Japan and 21 March 2009 in the rest of the world. The faster menu (compared to M3 Touchpod), build-in media player (including text reader, picture viewer, music and video players) and better controls (with the Unique Touch and slide navigation) make M3 Sakura the loader of choice for most M3 cart users.
One of the major downsides of M3 Sakura is it's mediocre Homebrew Compatibility. You can use the M3 Sakura Homebrew Compatibility List to check what homebrew does and does not work with M3 Sakura. You can also use Touchpod (which should be included with Sakura) to launch your Homebrew.
