No, I did not turn on the (M) Code (I even removed it) and I made sure that the cheats I wanted to use were enabled. The cheats I used were the Max/Infinite Badge Points and the Infinite Gold. When I start the game, the yellow text on top of the screen says that those codes are active (that should mean Dolphin is not at fault), but the game itself does not recognize that they are and just runs normally, as if I didn't put any codes in. Am I missing something, like a file, or is the game just being 'cheat-ignorant'?
Also, when I do enable the cheats. the textures of both Mario and his partners' faces are messy.
