RAM addresses (possibly useful for brute-forcing)
----------------------------
It seems each of the two flippers can have one of 10 possible altitudes when colliding with the ball.
The transition mode address could be used as a finishing point.
This list will be updated as I make more findings. Needed:
- collision/hitbox related addresses or anything that can be used for figuring out if the ball is touching a flipper,
- "star get" delay or anything that tells us we are getting a star / starkey
- anything related to "if a star exists", "if a star is descending or ascending", "if a star is grabbable", "star position"
- yellow coins / blue coins

$14AC Left Flipper Altitude (4-Byte)
$14B0 Right Flipper Altitude (4-Byte)
$14BC Left Flipper rising speed or something? (4-Byte)
$14C0 Right Flipper rising speed or something? (4-Byte)
Somewhere around here is also an address for each flipper that makes the ball receive speed if non-zero, but it is always zero. Maybe written to and cleared in-between frames.

$0200 1 Byte Cannon is pulling your ball?
Possible values:
0: No
1: Yes
$000C 1 Byte Current Blue Coins
(On the first room,
$0200 must be frozen to 0 and $000C to 0 to make L+R presses not reset the cannon and make the ball not enter the toad's tent,
if running Basic Bot in Bizhawk.)
Get key while dropping down.
Unfortunately, you won't get the Yoshi egg, so it's too slow.
Doing it like in the gif is only 20-30 frames faster exit than Save&Quit.
I found a suitable route change, see below.
I'm a good 2 seconds ahead in the TAS.
______
Old route:
- Ice (get Yoshi egg - used in Desert)
- Desert (get Lightning - used in Fun Fair)
- Fun Fair (get Lightning - used in Grass)
- Grass
- Bowser's Castle
New route:
- Ice (get Yoshi egg - used in Desert)
- Grass
- Desert (get Lightning - used in Fun Fair)
- Fun Fair (get Lightning - used in Bowser's Castle 3 fly-guys room)
- Bowser's Castle
Not using Fun Fair's Lightning in Grass costs 2.5 seconds, but you will get the 3-fly-guys star immediately, which should save 7 seconds back.
