To make a LEGIT cia we need to BUILD the CIA from the pre-installed content of a hardware. I.E LEGIT CIAS where created from the Pokemon X and Y bundles from nintendo 2DS. I have a NEW 3DS LIME GREEN that came with Super Mario Bros Bundle. In order to downgrade it i've used the Plailect system transfer guide. In the process the system was formated and i "lost" the pre-installed content. After downgrading, hacking with a AL9H and update it back to 11.2, i entered ESHOP and downloaded the game again. I Wonder if i still can make a LEGIT cia from this downloaded contend, because i've tried the Decrypt9 to extract the CIA and it could not identify it as a LEGIT one.
