Okay this one ended up being more interesting than expected. I was thinking that even 0xA you could just use the boo powerup and walk all the way to the moon, and then use the gravity field while entering the moon to orbit around the planet to collect the star. What I wasn't expecting is that you couldn't actually cross the small gaps in the rotating platform with just a spin because of how fast the platforms rotate and how spinning kills your horizontal speed. So the follow up strat was to bring the Magikoopa all the way to the end of the level, and have Mario fire boost to the moon/star (Shoutouts to Annoying for pointing out that the Magikoopa lands on the moon if you manip it far enough.) The problem is that once the Magikoopa shoots the fireball, they immediately go somewhere else that's out of range of shooting starbits to manip the Magikoopa further. So the final solution was to use P2 0.5xA to interrupt the Magikoopa's post-fire-shot animation, which keeps the Magikoopa in place so they fire another shot. I was then able to use one shot to get to the moon, and then another shot to boost into this star. While this strat should work with just P2 A, I was having a hard time keeping the magikoopa on frame with 0xA on P1, so I also ended up using 0.5xA as P1. Overall, a lot cooler than expected.
(Note that I forgot to add in P2 0.5xA when making this TAS until halfway through the level so technically this TAS isn't 0.5xA because P2 holds A midway through the course but this had exactly 0 impact on the game and I already reTASed the start of this stage like 4 times so whatever)
