Wait, homebrew works on Dolphin now?
Man, I need to get a new laptop.
Aside from emulators, I have my two cents to point out now. I know you're asking for glitches, but not many casual hackers are good at finding them, so i'll focus on gameplay. The only 'glitch' I found, per say, was that his winning-waiting animations are completely frozen. Not that it freezes the game, but rather the animation is frozen.
MASSIVE GAMEPLAY REVIEW TEXT WALL. DO NOT READ IF IRRELEVANT.
All in all, Cloud has no obvious weakness to be exploited. His worst point is getting back on stage, and it's mediocre at worst. His Side-B and Up-B are fine for recovery. His Up-B moves are also bad at hitting people.
You want to really beat Cloud? Get a character with projectiles.
There's no way to approach him without them, and when you do, it can only get worse.
From above? His Uair will juggle you, no matter how long the dodge is. For variation, try Nair instead and laugh when opponents can't get away from it's huge hitbox.
From below? Expect a Dair, Toon Link style and less lag. Or a Down-B. Slower, but great for off-stage spiking.
From the side? Cloud has two projectiles (Neutral-B and Down B) that can be predicted and dodged, but off-stage they become scary edge-guarders. His Foward Smash is fine for dealing with people that are good at spacing.
His F-tilt is mediocre, his D-tilt is better than Ike's, and his U-Tilt is magical. Compare the Utilt to Sheik's Ftilt.
Is Cloud on the ledge? His Side-Aerial move will hit anyone waiting for him, with it's massive reach.
It's so satisfying to land a full Aerial Neutral B on someone.
And there's my gameplay review on Cloud. Balanced? Nope. Legit? Yes. It's Cloud Strife, he's supposed to kick everyone's a**.
