I'm having a slight issue with my Mr. Game & Watch. Beforehand, I downloaded a Naruto PSA for him, then later decided I didn't have any use for it. After removing the PSA and eventually the "gamewatch" folder, I started seeing some odd results when using him.
None of his items appear when he does smashes or aerials (such as his f-smash torch), his color never strays from black (so if you pick light blue, he's still black, pick red, still black). The strangest result of all is when G&W uses up special. When on the ground, he swings back and forth, as if on an axis. When you try to use his up special in the air, nothing happens. I tried downloading the default game files for G&W and setting that in a "gamewatch" folder, yet I get the same results.
Now, whenever I don't load from Homebrew, this issue never occurs. I try loading from a different SD card from Homebrew, and the results are just fine. I attempted to format this SD card, but I'm STILL not seeing anything.

tl;dr: My G&W is broken, how do I fix it?
