Homebrew [Release] FirmwareDownloader

[admin]

This is a small app i've been working on as a side project. It downloads firmware files from NUS and packages them as CIAs for ease of upgrading/downgrading.

NOTE: since many factory installed titles (and some older titles) aren't available on NUS anymore, this cannot download all titles needed for a complete downgrade or a complete region change.

Attempts to download all available titles for chosen firmware. 404s are skipped. Firmwares are downloaded to /3ds/FirmwareDownloader/updates/<system>_<region>/<firmware_version>.
ctr = Old3DS, ktr = New3DS.

Controls: LEFT/RIGHT move cursor. UP/DOWN change value. START exit from menu.
When downloading, the app doesn't check input again until all titles have been downloaded, so the only way to exit is L+R+DOWN+B (on hax versions that support this).
