I used the official SDK to build a Unity project of mine. I tried to switch the dev mode of my console to UNITINFO in Luma but failed to install the CIA made by Unity. I just decided to use a tool to convert my .cci(.3ds) file to .cia. I tried 3DS Simple CIA Converter, but when I select the roms folder (with the .3ds file in it) nothing happens. The built .cci file is 0key'd, so I shouldn't need to generate anything. Using 3DS Simple CIA Converter 4.3(latest).
