SOLVED Problem with ROM set

[noob]

So I downloaded a 32 gb image from the youtuber "xxx," and I am having trouble with how to get the rom sets to show. When I download the torrent it saves as an rar. After it downloads, I extract it to make it an image. What would be the steps after that? I am stuck because I can't see any rom sets or emulators. It just saves as a 26 gb image. How would I be able to get the files onto the raspberry pi so it can run on recalbox? It is recalbox compatible. Can someone help me with a tutorial with all the steps laid out? I tried to follow youtube videos, but no one has the steps to install a rom set done by We're Dirty Gaming. I am a noob, and this is my first build of a raspberry pi. I would appreciate any help I can get because I feel like I have failed.
