Pokémon Crystal - Route 29 manip tests & new Entei step regu

Pokémon Crystal - Route 29 manip tests & new Entei step regularization attempt

-----

Optimal movement :
> Talk to Mom from above
> No additional tile anywhere alse

> Following glitchless movement, 128 steps to P3T4

Tests :
> Adding 1 tile to optimal movement (in Elm's Lab)
  - R (#6) => Rattata P2T3
  - DU(#5) => Poliwag P4T3

> Adding 3 tiles (1 Elm, 2 R29)
  - RD(#3) => Rattata P3T7
  - RL(#7) => Hoothoot P2T5
  - R (#6) => Hoothoot P1T7

NOTE : it seems that
 1) Having a different PoisonStepCount (StepCount % 4) on the saving tile for manips introduces very fast divergent RNG patterns
  >>> has been observed consistently
 2) Having a different StepCount (even with same PoisonStepCount) introduces divergences at steps k*256 and k*256 + 128 (happiness check & egg check respectively)
  >>> has been observed
 3) As long as a manip doesn't involve going through happiness or egg checks, the RNG ""should"" be consistent as far as the party count is the same (because DoPoisonStep routine goes through all the party to apply poison ticks)
  >>> not tested yet, but seems to be the expected baheviour, from the source code

Fixes for next manips :
- let 'ManipStepsTotal' be the number of steps involved in a manip
- let 'StartStepCount' and 'StartPoisonStepCount' be the value of StepCount and PoisonStepCount respectively when starting the manip

> short manip (done without going through happiness nor egg checks, i.e. ManipStepsTotal <= 127)
	1) StartPoisonStepCount should ALWAYS be the same
	2a) StartStepCount + ManipStepsTotal <= 127

> average manip (128 <= ManipStepsTotal <= 255, goes through Happiness check)
	(1)
	2b) StartStepCount should be the same as the manipped one
	3b) your party count should be the same as the manipped one (Eggs don't matter)

> average manip (128 <= ManipStepsTotal <= 255, goes through Egg check)
	(1)
	(2b)
	3c) (3b) AND the number of eggs in your party is the same

> long manips (ManipStepsTotal >=256)
	(1)
	(2b)
	(3c)

The +x are just showing how many extra tiles we're taking compared to the shortest possible movement. The values displayed as hexadecimal (and their conversion to decimal) are the values as off the current glitchless route movement.

Being seen by an NPC doesn't update the StepCounter, neither does the Repel wearing off textbox, an overworld event (phone call, door, tutorial-like movement)
If a spinner catches you, since the StepCounter won't be updated on a tile it should have been, your overall StepCounter will be 1 less than expected. Consider that for manips.

Area location		StepCount	PoisonStepCount
Route 29			0x35		0x01
(_PoY spot)			= 53
	> NOTE : safest patch movement (+4 to optimal)
Elm's call			0xF0		0x03
					= 240
Catching Tutorial	0xC7		0x03
					= 199 [256+199]
	> NOTE : safest patch movement (+4 to optimal)
After Youngster 1	0x66		0x00
					= 102 [512+102]
	> NOTE : less tiles in grass near blue-haired NPC (+2)
	> NOTE : no Mom call (we call her ourselves - optimal)
	> NOTE : taking the Potion (+4 to optimal)
Elm's call #2		0x0F		0x03
					= 15 [512+256+15]
Union Cave entr.	0xD2		0x03
	> NOTE : skipping the Full Heal saves 10 steps
Well entrance		0x93		0x03
					= 147 [1024+147]
Well exit			0xAE
					=
After Bugsy			0xDE
	> Azalea Gym movement takes the right path (fighting Al saves 4 tiles)
Bike menu 			0x36
					= [1024+512+ ?]
Whitney				0xC8
					= [2048 + ?]
	> NOTE : movement to the sister was Up, Right
After shopping		0x77
					= [2048 + 256 + ?]
	> NOTE : early Radio Card adds 8 tiles
Sudowoodo			0x4B
					= [2048 + 512 + ?]
	> NOTE : grabbing the Hyper Potion adds 10 tiles
Burned Tower entr.	0x9F
					= [2048 + 512 + ?]
After Rival			0xC4
Entei saving spot	0xEE		0x02
(ExarionU)			= [2048 + 512 + 238 = 998]

So far, if we want the StepCounter to not mess up the manip, we need to :
	1) have a consistent movement after the Rival, since it sets up PoisonStepCount to 0x02 (can search for manips with a different PoisonStepCount as well)
	2) either get Entei under 17 steps
	or 3) deliberately do 18-45 extra steps in order to have the full Repel cycle not altered by happiness check
		> these numbers are to be adapted according to how many execution errors you've made, how you adapted your overall movement (skipping Potion, not calling Mom, alternative Azalea Gym trainer fights, dodging bad Goldenrod NPC patterns, etc.) and how many spinners hit you during the run.

Trying Route 29 manip post Rival 1

205/3, need to reach 53/3
> comparing to glitchless movement, 2 extra steps before Rival 1, 102 after (25*4+2)
	> 4*24 + 6 tiles to saving spot

More notes on going up to Entei spot

Current movement ends with StepCount = 0xEE (238). The attempts will set StepCount at 0x0
This means you need to take 18 extra steps before doing Burned Tower movement to Rival 3, assuming everything went as planned below.
> If the number of steps you need to take is odd, you can exit Burned Tower once after Eusine talk to make it even.

Current movement :
> Safe Route 29 (twice)
> Near Lass, taking right path
> Call Mom on Route 30
> Grab Route 31 Potion
> Route 32 Repel from below
> Azalea : Kurt -> Mart -> Full Heal -> Well Entrance
> Azalea Gym : right path

Movement variations :
> left Route 30 near-Lass movement : +2 steps in Ecruteak
> skipping Route 31 Potion : +4 steps
> skipping Azalea Full Heal : +10 steps
> taking Ecruteak Hyper Potion : -10 steps

Trolls :
> hitting a spinner : +1 step for each hit
	- Russell : +0
	- if seen by Ivan on 1st possible tile of pass #1/#3, -2 steps
> Route 30/Azalea/Goldenrod : generally -2 steps each, exception(s) :
	- Railroad Youngster : -0 if you dodge him correctly
						   -2/-4 depending on pattern

	- Sudowoodo Sister : -0 if she walks left
						 -2 if she walks up
						 -4 if she walks right or down
