Because sudofox's service is amazing, I wanted to share the love with 3DS users. You will need NUS Downloader, and DSi's Common Key (Hey look at this - NUSD works on Wine) make_cia for your OS An Internet Connection A CFW with sigpatches and TWL_FIRM sigpatches (listen I know I could just say Luma but some people don't use Luma OK?) Steps: Open NUS Downloader, and update database. Download Flipnote Studio for your region, and ensure decrypted is on. Use make_cia to convert the APP file to a CIA - "make_cia --srl=FILENAME.app" Install the CIA. Use the ds.sudomemo.net proxy with port 80 Yes, it's this simple. If you're a DSi Sudomemo user and you have not hacked your 3DS, use https://3ds.guide If you're looking for more than just DSi Flipnote Studio and want an alternative service for FGW, try out kaeru:world.
