Some Crystal ideas :

Part 1 :
* letting your mother see you in the beginning is ~0.1 seconds faster
* healed immediately after Rival 1
* renaming a Pokemon 'A' takes ~1 second
* lv4 Hoppip gives exactly 42 exp., just enough to reach lv8 before Spearow (Rage x3 can be a range, what about Leer + Scratches ?)
* lv4 Poliwag gives 48 exp. (Scratch x3 ? Leer + Scratch x2 ?)
* Fighting the first Youngster after the second one is not worth it (12 tiles + text + fight = ~47 seconds) for 48 exp.
* calling Mom is still worth it (Poliwag is unlikely to troll with extra Bubbles if going for a catch, 1-2 per Bubble)
* holding the Start button in the main menu buffers its closing (can be used after exiting the Bag)
* take the PrzCureBerry from the bottomm of the tree (3 turn frames instead of 4)
* Route 32 (north) : Repel from the left side  (17 tiles [~4.2 seconds], 11 opportunities to get an encounter)
		     Repel from the right side (26 tiles [~6.4 seconds],  7 opportunities to get an encounter)
* Route 32 (south) : Left side  (48 tiles, 15 opportunities to get an encounter)
		     Right side (58 tiles,  7 opportunities to get an encounter + 1 Spinner pass)
* don't talk to the Blue Slowpoke Tail sellor (3 turn frames instead of 4)
	=> saying "No" is 31 frames (instead of 49 frames for "Yes")
* go talk to Kurt before Mart Shopping saves 2 tiles
* Azalea shopping :
	- 2 Potions (3 if hit any spinner)
	- 3 Super Potions
	- 5 Repels
	- 2 Antidotes
	- 1 Paralyz Heal
	(remaining : 86$)
* not taking the Full Heal saves 10 tiles and the Full Heal jingle
* Slowpoke Well : 29 opportunities to get an encounter
* Walk vs. Bike : 
	- 7 steps or less : Walking is faster
	- 8 steps : very close difference (< 0.1 second)
	- 9 steps or more : Get on bike + biking is faster
* Underground : taking the safety healing items (Super Potion & Paralyz Heal) before fight the second trainer saves 1 turn frame
* Goldenrod : Bike from Center to Mart
* Goldenrod Shopping :
5F	- Sell Mud-Slap & Attract
	- TM33 Ice Punch
3F	- 1 X Speed
	- 1 X Special
	- 2 X Attacks
2F	- 6 Escape Ropes
	- 2 Repels
	- 3 Full Heals (not sure)
	- 1 Pokedoll
	(remaining : 10$)

Part 2 :
* Buying 3 X Specials instead of 1 in Goldenrod 1 allows very-late Goldenrod 2 shopping
* Bike from Chuck's Gym to the Secretpotion man (4s instead of 4.2 seconds walking)
* Bike from Mahogany Center to the Rocket HQ
* Bike from for the Rocket HQ to the Gym
* After-underground shopping saves 3 seconds (and an Escape Rope in Goldenrod 1)
  => Instead of using an Escape Rope, reach the Mart with underground elevator
* Can't escape Radio Tower by any mean
* Radio Tower 2F : talking to last Grunt (7 turn frames, 11 tiles = 183 frames)
		   seen by the Grunt     (5 turn frames, 8 tiles, 1 "!" ~= 199 frames)
* Ice Path : if a Repel wears off while sliding, the movement will continue (can't change direction when the textbox appears)
* Tohjo Falls : go the closest to the blue guy possible (saves 8 tiles)
* If lv 7 for 1st Youngster, Rage saves 5-6 seconds
* Fighting Josh in Azalea's Gym is possible, assuming hitting Anthony and survived
