In the newest patch if you lose Sudden Death, but you will quit the match just before the end, you will actually win.

I don't know is this in mp too, but did anyone tried kamehame while goku is super saiyan? kamehame is much shorter then his regular form

This is inconsistent - as far as we can tell, only stage hazards/items can cause this. Can you attach your replay and tell me the desync point?

You can be knocked out of Sora's (and maybe Lloyd's) Final Smashes, and they don't always pull people in if they hit. I got hit by both, on two separate occasions, and got stuck under them until they were done. Took no damage, and I was free to conterattack.
Also, there's one ledge in Skull Fortress that has the same "Can't use ledge attack" bug as in Clock Town. It's the lower right one. And the AI still doesn't know how to avoid the enemies coming out of the fortress.

In Target Test level 1 (don't know if levels 2 and 3 also have this), when I break my previous record, sometimes the timer doesn't stop right away and is late by about a second at most (I had a 0:08:21 record for one time, and broke it with something around 0:07:80, but the game shows a 0:08:70) while still saying "New record". The delayed record appears on that character's results, and doesn't change when you get a time shorter than the number written but longer than the actual time of the record.

Really salty about this since I got some good times that had this bug and can't get a picture to make proof

Lloyd's final smash also seems to freeze the enemy in a tumble state if done from some distance away (not sure if max range). It deals the damage but no knockback. No vacuum effect either, the enemy will remain in a tumble state at his original position until he's knocked out by another move/stage hazard.

This hasn't been patched since 0.8. A glitch would happen in Shadow Moses Island with Tails doing a back grab near the wall instantly K.O the player.

Before the patch, when Goku was in his Super Saiyan form and charged a Kame-hame-ha, it wouldn't fire at all, but Goku still did the firing animation. After the patch it was sort of fixed, Goku now fires the Kame-hame-ha, but the range stays the same regardless of how long you charged it and Goku won't turn into Super Saiyan 3 once he fires a fully charged one.

This, it doesn't seem to use the correctly charged attack. Same range and 15 damage always

You are right, I had a match that was desynced, where items were on. The others were fine.

Found out from a friend that this happens if you open SSF2 without first having played a match. If you start up a match, exit immediately, then view a replay, you won't get the black screen.

Don't know if someone already posted this but a very, VERY common glitch is happening when a cpu gets close to a item somtimes they keep spazzing out back and forward over and over.

Wait... Wario used a side special, and I tried to catch him with Falcon's Crest, (Lloyd's FS) but the two attacks cancelled each other out. Something isn't right here.
Also, when Wario uses a Star Rod and swings it normally, stars come out, but they don't when he smashes.

The following characters do not gain invincibility frames when they perform a tech roll.

Wario, Peach, Kirby, Mega Man, Naruto, Sonic

Characters who do not gain invincibility when they perform their get up attacks.
Sonic, Marth, Tails, Lloyd, Kirby, Mario, Donkey Kong

Very helpful, thank you.
