(gonna continue this one for left mid after)
-> Alright, if the game does a bit check for MID LEFT, then I assume it gives left mid if 1st bit = 0, but at least one of the 2nd and 3rd bits being 1.(edited)

it is from the txt that i made manually when I was using taco´s rng hack and cheated the rng value to different values
thought i´d try to make sense of the values and the pattern, bec the samples should be many enough

and bec hackers dont wanna help me in figuring out the stuff from here https://wiki.supermetroid.run/RNG1   even though I've asked a few times by now and also asked what I could offer for them to look into it FeelsBadMan

https://www.binaryhexconverter.com/hex-to-binary-converter
using this thing atm

if anyone wants to help figuring patterns, maybe for draygon stuff
maybe if i cant ask them do figure out how phantoon does some stuff, i maybe can already give them a good shot at what to look for and what it should be so...

RIGHT FAST: Really looks like it checks for 1st bit being 1, and 2nd bit being 0.

LEFT SLOW:
result: It seems like it checks for the first 3 bits being = 0.

its not so many samples of this case in the small loop, so it might be that the actual check is a bit (hahaha, quite literally) weaker than that, but I'll take it for now.
and those are btw all different phanny patterns one can get in the small rng loop (except 1st round)
just 4 patterns

lets see draygon

SWOOP, NO TURRET SHOT (i.e. top left turret shot):
Seems to check 1st and 2nd bit to be 1.
And I think this one was wrong when i noted it: 1010 1010 0100 0001

gonna check that
so swoop might be about 1/4 chance?
also the rng hack is this one, for anyone wanna use the cheat tool to cheat values for the address 7E05E5 and 7E05E6, and check what results occur for different values.(edited)

yeah i was right
AA41 (swoop, top right)
thats how it should be in the txt
like this
now next pattern....

lets check draygon diving/gooing to the left.

SWOOP & TOP RIGHT (turret shooting):
It seems that the game checks for 1st bit being 1, and 2nd bit being 0.

Guess to know what exactly the chance is for draygon to swoop, I´d need to cover all bit check options
so 1/4 shouldnt be all of that chance but just a smaller part
actually, from my notes it seems that "dive, left" meant draygon diving generally (if left or right side), and left turret shooting
okay so draygon patterns...

goo, bottom right:

DIVE/GOO, BOTTOM RIGHT (turret shooting):
Seems that it checks 1st bit being 0, and 2nd bit being 1 for this case.

now there's a few special RNG values remaining in the small rng loop, which make draygon spit exactly 1 goo, for a few different angles:

Aran;Jaeger-Today at 9:30 AM

0000 0110 1010 0000 (diag. down 1st goo angle)
1001 0000 1000 0000 (almost hor. 1st goo angle)
1011 1011 0111 0000 (steep diag. down 1st goo angle)
XYXX XXXX XXXX YYYY
If I had to guess.... then the first 4 bits need to be all 0 for draygon to spit goo, and for the angle....
not sure how many exist, but might be 16/4 (4 vert and horizontal ones for full circle and diagonals, times 2 bec there's steep angles aswell, but then only about 1 quarter of the whole circle is used... so maybe 4 angles?)(edited)

there´s only those very few rng values in the small rng loop that make draygon spit goo
first 5 bits cant be deciding it all
because then 1st and 2nd sample would lead to same result
and if we assume it only extends checks from smallest bits to higher ones
then smallest 6 bits would make the difference
the xxxx xxxx xx01 0000 case would then be missing
okay so there´s 4 angles for the goo
and almost horizontal one, an almost vertical one, and 2 angles that are a bit off from the 45° angle
and as known, the goo cycles through those angles (from top downwards)(edited)
time to mess around with the rng hack again...

okay 00 01 = ceres ridley fireballs

Aran;Jaeger-Today at 10:00 AM

for 00 02 too
which is slightly odd
00 03 aswell, but 00 04 is ramming
checks the first 2 bits i guess
00 05 is ram aswell

The colour of a tile seems to be determined by the high byte, i.e. the value of the (unsigned) address 7E05E6:
If the value is equal to or larger than 0x80, the tile is black, otherwise it is white.

0xxx xxxx xxxx xxxx seems to correspond to a tile being white
1xxx xxxx xxxx xxxx seems to correspond to a tile being black

(There's no explicit list of RNG values in binary representation as samples and grounds for the heuristic claim other than the above values and about a dozen randomly chosen RNG values to check this claim.)

- - - - - The conclusions that I draw from the pattern given by those few samples (the first 16, and 2nd 16 RNG values, aswell as the largest 16 RNG values) is:
Ceres Ridley's next attack is determined by the first 4 bits alone, in the following way:

Fireball attack:
xxxx xxxx xxxx 0000
xxxx xxxx xxxx 0001
xxxx xxxx xxxx 0010
xxxx xxxx xxxx 0011
xxxx xxxx xxxx 1001
xxxx xxxx xxxx 1111

Ram attack:
xxxx xxxx xxxx 0100
xxxx xxxx xxxx 0101
xxxx xxxx xxxx 0110
xxxx xxxx xxxx 0111
xxxx xxxx xxxx 1000

Circle attack:
xxxx xxxx xxxx 1010
xxxx xxxx xxxx 1011
xxxx xxxx xxxx 1100
xxxx xxxx xxxx 1101
xxxx xxxx xxxx 1110

Assuming a uniform distribution, this would correspond to the chances
6/16 = 3/8 for a Fireball attack (2 sets of fireballs constitute 1 such attack)
5/16 for a Ram attack
5/16 for a Circle attack

For all these right slow patterns, the binary representation of the RNG values have 1st and 2nd digit equals 1.

The resulting Botwoon patterns (either fixed movements/actions or oscillating ones) seem to not only depend on the RNG value but also on Botwoon's previous pattern, which can lead to different results for the same RNG value!

The phantoon tests were all done from 1 same savestate when Phantoon was about to end his enraged state from getting hit by a Super Missile, and Samus had full Missiles and Powerbombs, but not full health and Super Missiles.

01FF Cycle Smallest Loop Draygon Patterns.txt
(Draygon's action (either swoop or dive) (gunk happening or not), turret shot position(s))
full spam means the turret kept charging shots and shooting even during Draygon's dives (where he'd normally spit goo in a gunk phase). And in some combination of turret that is firing and direction of Draygon diving, turrets can keep firing and will not stop (see: Left turret when Draygon dives towards the right), but those cases might be improper artificial situations. And otherwise, turrets always stop firing when Draygon comes close while diving, and in general, turrets keep always firing as long as Draygn doesn't dive.
It seems a given fixed RNG value alone doesn't fix the direction to which Draygon dives, but only if he does or not, and the direction depends on the previous situation.
Draygon (so far) seems to never dive twice in a row. And a turret shot spam always is cancelled at some Draygon-position dependent point (close enough to a turret) during dives.

My conclusion from these samples is: Crocomire's next action depends on the 1st digit of the high byte lying in the range from 0 to 3, or lying in the range from 4 to F instead.

xxxx 00xx xxxx xxxx seems to correspond to Crocomire spitting

xxxx 01xx xxxx xxxx seems to correspond to Crocomire crawling
xxxx 10xx xxxx xxxx seems to correspond to Crocomire crawling
xxxx 11xx xxxx xxxx seems to correspond to Crocomire crawling

Assuming a uniform distribution, this would result to a chance of 1/4 of Crocomire spitting instead of crawling which would happen with 3/4 chance.
