Adding Mario Kart Wii ghost file to .ISO

[exo]

I was wondering if there was a way for me to somehow insert a mkw ghost/replay file (.rkg) into my ISO of mkw. I got this replay off of a leaderboard website and I wanted to view it in the emulator.  

here is the rkg file i wish to add to my game

In the same menu as your first screenshot, right click disc and choose extract entire disc. After choosing the location, you will either need to add DATA\sys to your dolphin paths or enable search subfolders if you have extracted it inside your normal games folder. At that point, you can just modify the filesystem. IDK if the ghost numbers follow ingame order, though.
