some games don't need CFW to be played, if the game is sold in physical disks and you're not trying to install their DLCs, then you don't even need CFW.
now to install this game, u have to create a folder in your sd card root directory called 'install'
create a new folder inside the install directory with your game name .. and then install normally using Wup installer, if the game is only available on Eshop, you will need to run CFW first before running Wup installer.
