TWiLight Menu++ Updater has been discontinued once again (for a while, actually). Universal-Updater 3DS has gotten better during each release, so it's now the recommended updater tool to use, with a slightly faster and stable updating experience!

TWiLightMenu Updater

TWiLightMenu Updater is an open-source updater for TWiLightMenu++
