Yeah, I tried hyper speed wallkicks, it didn't work for me (Or required too much patience rather). The more speed i got, the longer it takes to get more speed, and the camera is all jerky making it harder to gain speed, so I gave up after it seemed unlikely.
You can BLJ from the elevator into the mansion, but there's no way you can get to the top floor and still have speed to get through that wall... One possiblilty somene thought of was getting inside a pillar in the mansion and jumping up it and appearing in the upper floor, but no one has managed this.
The star in Snowman's Land "Into the Igloo" seems impossible to me. I BLJed into everything I could with max speed, nothing worked out... Mapler90210 tried hyper speed wallkicking, it didn't work either.
In CCM, there's no way to get into that chimney with the coins in the way it seems. The only two ways would be to go through the chimney with a BLJ somehow (No one has done so) or you could get in there with 0 health, but that's useless because you would die as soon as you got inside. This makes the first two stars of CCM impossible CCCless, as well as the snowman's head one.
Dire dire docks, collect the caps, I havn't really tried myself, but we would have to find a way to get out of bounds and then go around the cage that way...
Mario Wings to the sky in Bobomb's Battlefield is impossible because the checkpoints have a coin right next to it, and it seems impossible to activate the checkpoints without collecting the coins.
Edit: Not so sure about the 0 health CCM chimney entry. Never tried myself, and I can't remember how having no health left and interacting with coins works. Does he collect them? Does it add to his counter...
