if you registered to the nintendo dev portal and installed redacted then you probably checked what's in the sdk in the sdk you can find a folder named release with csu and pre made cia the cia will not work on a non devkit system but if you have a 3ds with godmode9 you can copy all the csu and using the custom firm ware you can build a cia that can be installed and then you can install them with fbi you dont need any pc converters only the csu and a 3ds with godmode9 when you go to the file that has the csu you can select them with L then pres a on one of them and select ncsd image options after that select build cia then when its done all the cias will be in the gm9/out and blam your device compiled 99% of the cias for me it failed to compile one but all the dev tools on the 3ds work btw i suggest using a new sdcard yust for the dev tools and one more thing enable dev info mode to install the cias you can do that by pressing select while turning on your 3ds and selecting dev info mode
