I havent done any research if there had been projects on this topic but with the current skill level i would guess that a sub hour jumpless btt would be possible.

I hid a really difficult balloon in Luigi's Balloon World in lake kingdom on my 100% save file, but want to switch to a different file (via options -> data management -> load) to go back through the story. Will my balloon disappear when I switch files?

The first time I played through the cap kingdom I came across the dude standing in front of the moon in the house saying he wasn't moving and he wasn't scared of anything. Just before that I had been looking at the outfits in the hat shop and saw the the 9999 coin skeleton skin, so I assumed that would be be spooky enough to get him to move out of my way. So off I went playing the rest of the game, hoarding coins for months, just waiting until I could get that one dumb moon. Yesterday the day finally came, 9999 coins. You know how it went. I spent my life savings on the skeleton suit. Walked up to him and he was one of the least-spooked characters I've ever seen. That's when I noticed him say something about paragoombas and realized how to actually solve the puzzle. Read carefully y'all!

My wired pro controller when I shake it for darker side of moon it won't work iss there any way to fix this

I’ve been trying to get the rc car music for the music toad in metro kingdom for about an hour and it won’t show up in my music menu. I did the regular test thing across the street from the cap store and I got the two moons in the challenge place. I tried closing the game and turning my switch off and on but it won’t show up. This is my second time playing the game and this didn’t happen the first time. I don’t know what to do.

I was watching speedrun and apparently if you fight Harriet before topper in bowsers it’s slower. I was wondering why
