### Required Reading

Soundhax (when combined with pre9otherapp) is compatible with versions 2.1.0 through 8.1.0 in the EUR, JPN, KOR, and USA regions.

{% capture notice-1 %}

Note that cartridge updates will only deliver updates to core features, such as the System Settings, Home Menu, etc. cartridge 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 cartridge update from a version containing an older Nintendo 3DS Sound version *(<2.1.0)* to one that introduced a newer Nintendo 3DS Sound version will break Soundhax! You will need an alternate method of entering the Homebrew Launcher such as [Installing boot9strap (Browser)](installing-boot9strap-(browser)) or [Installing boot9strap (MSET)](installing-boot9strap-(mset))!
