Super Mario 64 DS - Bowser in the Sky Red Coins in 0 B Presses

This strat takes 0.5 B presses on the second revision of SM64DS, v1.1, and the PAL version. This is because of how bouncing on enemies works: on v1.0 you will continue doing the action you were already doing after a bounce, e.g long jumping onto an enemy means you will stay in the long jump animation after bouncing. On v1.1 and PAL, you will always be set to a state as if you had just done a regular jump. This means that to get any significant height on v1.1 and PAL you have to hold B, while on v1.0 you get a decent amount of height from bouncing after a slidekick recover, enough for this strat to work with 0 B presses.
Super Mario 64 DS BBC made a video of the 0.5x strat:    • Bowser in the Sky: Red Coins in the Sky (0...  

For an explanation of what happens up until I enter the pipe, see my video of beating Bowser in the Sky in 0 B presses without red coins:    • Super Mario 64 DS - Bowser in the Sky in 0...  
After entering the pipe, I die and reappear outside. This is necessary as it means the goomba used to get off the pole respawns. I can't just collect all the coins on the way up because there is no way to get the coin on the wooden platform in 0 B presses without falling down from somewhere past the pole. Previously the star took 1 B press by either jumping up to the coin on the wooden platform, or using a press to jump off the pole the second time around, but my realisation that you could respawn the goomba brought it down to 0.
Getting the red coins from here is pretty simple for the most part, and I use the same trick as before to get past the rotating platforms. The last red coin is the only notable one: I need to bounce on a goomba to get back up the ledge. To get a goomba in Yoshi's mouth while next to the red coin I have to first eat it from the ledge, and the only goomba that comes close enough to be eaten is the one that I used to get into the pipe in my previous video. However it it possible to get into the pipe using a precise slidekick recover, so you can get the red coins and beat the game at the same time.
Instead of doing that I just get the star though. Dying after eating it still counts the star as collected: as you can see, the counter has already increased.

For anyone wondering, the current 150 Star B Press Total (allowing any version to be used for each star) is 39 B presses. The total only sticking to one version is 40 B presses, on the PAL version and also on the 1.1 revision.
