    I would like to install the Pokémon Neo X rom hack but it will conflict with the already installed Pokémon X game I have. Can I edit the title ID and game serial of the ROM/CIA to be able to install the game side by side with Pokémon X?

    But it's cooler to have those side by side on the home menu. :D

    yes, decrypt, extract romfs, rebuild .3ds using 3dsbuilder with a different title id and unique id, convert in .cia
