GLITCH HUNTING:
SIRENA1:
pianta1-style pause trick, tried to use it in sirena1 but it saves/wastes 0 frames.

There's a cutscene trick I haven't posted about yet.
Just study this video

Doing this in sirena1:

It can also be done at gelato2, bianco1 (goop piranha defeated cutscene), and possibly more instances.

RICCO2:
You can skip talking to the guy in the cave in ricco2, but the timer for the race doesn't start so you're forced to talk to him. I also noticed that pausing the game makes the timer run for an additional frame so you get worse times.

GELATO2:

Cutscene trick on mirror #2 (I name mirrors based on how many enemies are on them)
notes:
- when a cutscene gets started after each mirror, Mario is placed in a predetermined location. If you do mirror #3 first, he's placed in a location where he's on the floor, already standing.
- if you do mirrors in order #3 #2 #1, he gets placed in a different place after #1 than if you had done #1 first.
The cutscene trick makes Mario carry over momentum into a cutscene. If Mario is already standing (he's placed in a location where he's already on the floor), he can only move forward or backward. If he's placed in a location in the air, he can move wherever you want - just jump, walk, dive into whichever direction you want.

GELATO3:
Pausing just when the shine is about to appear delays the appearance by a few seconds. Can be done repeatedly. Probably there's a framerule address running through 256 frames, looping and trying to make the shine appear when it reaches zero. Doing the pause trick in Pianta1 apparently sets this address to zero instantly ?
