All game carts contain a copy of the required system version to play it, allowing anyone on a lower version to use the cartridge to update to that version (even without an internet connection).

{% capture notice-1 %}
Note that Cart Updates will only deliver updates to core features, such as the System Settings, Home Menu, etc. Cart Updates will not deliver updates to Nintendo 3DS Sound and Network features, such as System Transfer, Internet Browser, StreetPass Mii Plaza, or eShop.
This means that using a Cart Update from a version containing an older Nintendo 3DS Sound version *(<7.0.0 (EUR, USA) or <10.6.0 (JPN) or <4.0.0 (KOR))* will break [Soundhax](homebrew-launcher-(soundhax))! You will need an [alternate method](homebrew-launcher-(alternatives)) of entering the Homebrew Launcher!
