I checked the timing for the lightning bug using default combos.
Gulliver Pokeby's deck is the fastest so far.
The following combos do not flicker the screen:
Sickle Seek
Snitch Streak
The following combos causes flicker:
Deflect
Poison Immunity
Summon Umbrella
Conjure Snack
Drone
Tempest
I know a way to jump to almost any address in System Bus:

1. buy a chocolate frog
2. get to the upper left of the stage by pressing start as you enter a boss fight
3. move left until 0xCABC is a value where your payload is located
4. pause the game, use frog by Right + A to jump to 0xC970, nop slide to CABB, which jumps to wherever 0xCABC pointed to
5. Credits I guess? Haven't gotten anything interesting except not crash. Crashes almost all the time however.
The input file uses BizHawk 2.8. I can't figure out where to jump to do anything interesting yet; stuff such as item, card amounts, etc are all located in WRAM, so I don't know where else to go. If anyone knows, please help.
To prevent myself from accidentally losing it:

Sanqui realized using the Chocolate Frog puts you to WRAM bank 6, which is where items are located. They came up with a payload that took 47k sickles worth of items to setup, which gradually got bought down to 8k.
Rather than use Hogwarts dungeon, I realized I can leave battles using "yes" item, so I warped to the forbidden forest to get OoB, then executed the payload to credits warp.
It beats the game in 36,122 frames, or 10:02.03. I need to check something a bit more before submitting.

I was trying to improve it, and managed to get a whole bunch of glitched items without crashing.
Some discoveries:
1. It turns out that getting OoB from the troll in washroom doesn't mess with position address, so it can be used for ACE. This means RTA-wise, there's more items available for payload.
2. I investigated the stores. Weasley Twins Bargain stocks the following when you first arrive at Hogwarts:
Superior Work Robe
Superior Gloves
Dragonclaw Gloves
Superior Pointed Hat
Lined Hat
Fine Fettle Belt
Stamina Belt
Superior Boots
Hardened Boots
Copper Cauldron
Brass Cauldron
After one of the 5 classses post potions is done, it changes to
Superior Work Robe
Buckram Robe
Dragonclaw Gloves
Sorcerous Gloves
Lined Hat
High Hard Hat
Stamina Belt
Robust Belt
Hardened Boots
Brass Cauldron
Silver Cauldron
That means there's only a short opportunity to obtain Superior Gloves, Superior Pointed Hat, Fine Fettle Belt, Superior Boots.
On the 2nd visit to Diagon Alley, Potage's Cauldrons stocks the following:
Brass Cauldron
Self-stirring Cauldron
Madamn Malkin's stock the following:
Leather Belt
Plain Boots
Superior Winter Cloak
Nimble Gloves
Superlative Hat
Vigorous Belt
Superlative Boots
This makes it very difficult to stock them before you can't buy them again. I'm thinking duping money drops from blue turtle in 6th Floor Secret Hallway https://alpha.vgatlas.net/hp1/enemies/49
These drop 250-500 sickles per fight.
3. You can't sell Bastion Belts to stores. Wandwaving Gloves, Optimum Hat, Blizzard Cloak, Optimum Boots only appear as drop near the very end.
4. You can grind herbs by pausing right infront of respawn points for it. There's 16 herbs, so 16 bytes for payload.
5. 0E01 WRAM is recipies flag
6. 0DDF WRAM is minigames
7. House points are strange. It appears while there are certain points it awards all houses randomly, by the end, it is hardcoded so that either Ravenclaw would be ahead, or Hufflepuff. It doesn't seem possible for Slytherin to win. The shortest dialogue for any% no ACE would be to have Ravenclaw still be ahead after rewarded 170 points at the end.
I mentioned 2 of the card combos weren't obtainable; I think they can be obtained now.
Edit: Used BizHawk 2.8
