Rinka warping glitch

I just found this cool glitch yesterday. Don't know if it's known, but couldn't find anything with a quick search. Also, sorry for crappy image quality.

How to:
1. Freeze a rinka
2. Freeze a rinka next to it, but slighrly higher/lower, so that you can roll from one to another as a ball
3. Go on top of them and roll from the lower one to the higher one. If you can't, you froze them too far away from each other. If you can:
A: The game will instantly unmorph you to a standing position. If this happens, freeze the rinkas with the other one (left/right) being the higher one.
B: You'll roll inside the higher rinka's hitbox. If you roll too much into it, you'll jump on the higher rinka. Try to find a position where you are as much inside it as possible. (you can hear yourself jumping onto the higher one by listening to the morph ball jump sound.)
4. Place a bomb, unmorph to a crouching position
5. The game will warp you either up or down, even through blocks.

Things known so far

See dragonfangs' post below for more details, he figured out a lot about how this thing works.

1. Should work with most respawnable enemies. (mostly rinkas and pipe bugs. However, pipes spawning multiple bugs are another story. They work and don't work)
2. The game will warp you above the spawn point of the enemy you were standing on, regardless of your position in the room, but only vertically. Your horizontal position remains the same.
Upon killing them, the game will try to put you above the one you were standing on. But if they are respawning ones, they gain new memory values instantly after death, which results in you being put above the spawn point.
3. The placement (which enemy is higher, left or right one) depends on the enemies' memory values. The one you're standing on must be later in memory than the one you clip into.
4. Warping long distances (over one screen of height) in a tall room will cause graphical glitches that remain until you either pause or get them off-screen. (no need to leave the room)(http://i.imgur.com/u5NAdV9.jpg)
5. Tested and works on all versions of the game.

(Thanks ZX497 for the following two)
6. The glitch will trigger if both enemies are killed in the same frame, regardless of how they are killed.
7. Your pose doesn't matter. As long as you're in the "spot", touching the lower rinka and killing them at the same time, the glitch will trigger. You can be standing, crouched, running, turning or even morphed. But if you plan to use a bomb to kill the rinkas, morphing is not an option, since the frame the bomb kills the rinkas is the frame the bomb launches you, so you're no longer touching them.

Just tried on JP cart. Works on it as well. Can't figure out what to do with it, it just moves me to the ceiling then I fall.

Where did you try this, jaysee? Also, I'm currently trying to figure out how to record this thing on my computer using some emulator, but having problems finding a good one. Any suggestions? (new to emulating.)

Edit: Thanks bio. I'll get on it tomorrow, it's getting late here in Europe.

I did this in first 4 metroid rooms. I couldn't get rinkas to frozen at the right spots afterwards. I would say I would record this on Amarec, but that would include like 20 mins of me trying to set it up.

This is a really cool glitch. I've doing some TAS testing of this, and other enemy types don't seem to work... not sure about what in particular makes rinkas special, but yea. Here's some extra info:

- the glitch triggers when you kill both rinkas on the same frame, regardless of how you kill them.

- pose you're in doesn't matter. As long as you're in the "spot" and touching the lower rinka, this will work. So, you can be standing, crouched, running, turning, in the middle of a shinespark or even morphed. If you plan to use a bomb to kill the rinkas, morphing is not an option, since the frame the bomb kills the rinkas is the frame the bomb launches you, so you're no longer touching them.

Not too much add, I haven't figured out anything particularly interesting outside of the things Scrooge already posted about. If this doesn't work outside of using rinkas, there's not much you can do with this.

You can do this but there's no point.

west furnace access why

Can you go through doors when this glitch is active?

ZX497

2015-03-16 10:48:12 am

What do you mean, exactly? This glitch isn't "active" per se, it's just a one time teleport to a new vertical location... the game works just the same.

If you're wondering about the Out of Bounds, you can't get back in-bounds, because you're stuck above the ceiling. The OoB area is like a huge vertical shaft, with thin roof / floor separating you from the play area, and absolely MASSIVE walls on both left and right sides.

What did you hit in the video that ended your shinespark? Was it one of the rooms above or something?

west furnace access why

I was just thinking we might be able to skip mother brain with this, but by the sounds of it that's not possible. I was under the impression that samus falls through the floor, reappears above the ceiling, then falls through again indefinitely.

I hit the bottom of the room. There's nothing out there, I just shinesparked high enough that I wrapped around the entire area, and thus just collided with the floor... then I fell back down far enough to end up back on top.

And yeah, this doesn't actually warp you multiple times or anything, but I can definitely see why you'd think that from this video, heh. The reason it looks that way, is because the camera doesn't follow you to OoB areas, it's basically stuck on the room level. There's several camera lock glitches in the game like this, and they all look kinda funky unless you know what's going on.

I don't know how the game decides whether to teleport you up or down, but I tried it a few times in mother brain's room and it seemed to teleport you down with every rinka. I also tried to tp right below mother brain's glass thing in hopes of getting the power bomb, but the two rinkas in the MB fight get destroyed when you kill MB

ZX497

2015-03-16 11:27:54 am

Yeah I don't know how the game decides where to put you exactly, but minor variations in your height (about one map screen worth of height) do not make any difference: you get to the exact same subpixel. For example in the first metroid room, you can activate this glitch as close to the ceiling or close to the floor as possible, and you get to the exact same spot in the ceiling regardless.

Also, the PB tank doesn't actually exist in this Tourian: the pre-explosion and after-explosion Tourians are two different areas.

So I did some research (with helpful suggestions from Pyrq and Mobius) and I found the following:

- For this to work, the enemy you are standing on has to be later in memory than the enemy you clip into. Trying to do it unassisted this doesn't change much from it essentially being random, but with some useful scripts you can tell what will work on emulator.
- The "warp" is setting your vertical position to be on top of the enemy you are "standing" on, but the enemy is dead and has already respawned(memory values for the next enemy to appear get set instantly, but the enemy doesn't actually spawn until certain conditions are met). So essentially you get transported to the spawn point of the frozen enemy.
- This SHOULD work on most respawning enemies, a very notable exception seems to be pipes that spawn multiple enemies, where it is not possible using only the bugs from the same pipe. I haven't looked too much into exactly why so I might be wrong, but only the first bug actually respawns instantly, and it's already the first of the bugs(see my first point).

That's really cool info... I think my tests with pipe bugs failed cause of the triple pipe thing. Although, this said those pipes also DO work just by using enemies from the same pipe: you just gotta make sure all three are dead when when you activate the glitch. So, kill the extra one before doing the trick.

This will actually probably make Early Ice optimal for both TAS and RTA.

EDIT: ok, seems like you don't actually even have to kill all three from the same pipe.

Alright here we go, some sort of explanation. When you first get to that triple bug area in ridley, that pipe will NOT work. It has something to do with enemy priorities or something like that, I dunno exactly. However, there is a very easy fix for this: kill one of the orbs, and collect whatever it drops (if anything). And bam, just like that, the pipe will start working for this clip.

This is absolutely consistent for RTA. You don't need to time your shots to freeze the enemies, since the second bug that spawns has a freeze priority over the first one. Secondly, you don't have to roll from one bug to another, you can just land anywhere there, as long as you're on top of both, and it works.
