Wow, that's way easier than what I was doing. Thanks!

tap right for a short amount of time That's super helpful.

I'd need a video on what exactly you're doing wrong Paying attention to the flight meter is already helpful, but I can't get door 7 to be consistent for love nor money, so I recorded it:

Somehow while warming up beforehand I was getting the meter above 30 most of the time when I went through the door (on door 7), and I'm not sure what I was doing different.And is it really frames until you jump? As I could go through with like 10 on the meter, jump before it's exhausted, and not get the cape to deploy. 29 on the meter is the best I've done, and it looks like it just needs to keep the meter above 0 until the top or near top of the jump.

Thank you very much for the help

Hello! I just started learning 11 exit glitchless and I have a few questions.

Emulation: I can't use a capture at the moment, so I'm running on emulator. Unfortunately, I can't find a clean Japanese ROM, and none of them that I've found can be cleaned with romclean. Are there rules regarding unclean ROMs or ways to figure out if whatever the modified data affects the game in any significant way? Is it possible to just get a patch for a clean US ROM that'll convert it to a Japan version?

Technical stuff:

1. What exactly affects the fly speed you get? I've noticed that on Donut Plains 1 my fly speed is inconsistent, and it doesn't always seem to correlate with Mario's ground speed when I take off, but I may just not be able to read the numbers quickly (using the practice cart ROM) enough.

2. On the cape door trick in Bowser's Castle. I frequently don't get flight after going through despite having Mario in the flight animation when I enter. Even if I use room reset on the practice cart, sometimes he just won't fly no matter when I time the jump. I always hold forward and tap up to go through. Is there something I'm missing? If I'm accidentally dropping the forward input on the last frame or two, will I not be able to fly?

Thanks. I look forward to getting a halfway decent run to submit soon!
