Dolphin Emulator - Cheats Manager Disabled

I wanted to rape some GameCube games with Dolphin emulator as my Wii is fucked up and I don't want to mess around with it anymore, just to hack some GameCube games. Anyways, I went to the tools drop down menu in Dolphin and the Cheats Manager button is disabled. It's gray and that means it can't be used. Like, WTF?! I tried doing it on Wii games, before and after starting the game, etc. But still wouldn't allow me to use it!

If anyone could help me out, that would be great! Thanks!

Solved the issue by going to Options, Configure, ticked the "Add Cheats" check-mark box and pressing OK. I hope this helps out anyone else having this problem!
