I was watching the Super Metroid speed run, and I completely forgot about this glitch until now. We don't have all the details yet, but enough to start looking.
For reference, SNESlympics was a silly SNES challenge thing we did a long time ago with five games, goals, and set time limits. We would record movies to show what we did. They were sometimes funny, sometimes dumb. The person who did the best won. For Super Metroid, all there was was the .smc and the .zst. As of now, we don't know what version of the .smc it was and what version of ZSnes we used.
Apparently there is some glitch in the Space Colony scene during or after the bomb sequence that deposits Samus on Zebes. Entering Samus's ship ends the game. Here is the entirety of the conversation:
[02:48] Seppel: Since he has only 10 missiles 10 super missiles and 5 bombs.
[02:48] Seppel: No grappling hook nor speed boots
[02:48] Kavir: I got the credits where Samus only wears the skintight black bikini when SNESLympics bugged up due to my sheer incompetance
[02:49] Haze: a new speed record for SMB3
[02:49] Haze: they all follow the same path, no need to bother watching it over and over again
[02:49] Haze: KAVIR YOU SHOULD'VE SUBMITTED THAT
[02:49] Haze: HA HA
[02:49] Haze: "Super Metroid in 3 minutes"
[02:49] Kavir: I DIDN'T RECORD
[02:49] Kavir: AND IT WAS CLOSER TO 45 SECONDS
[02:50] Haze: if only we could figure out that bug.
[02:50] Seppel: Haha.
[02:50] Seppel: Mother brain is taking a long time since 10 missiles and 10 super missiles only goes so far.
[02:50] Kavir: I failed to jump out a single level up from the end of the corridor after failing to kill ridley
[02:50] Kavir: and tried to get up until the time ran out down there
[02:51] Kavir: then I wandered back and forth after respawning since I didn't know how to open doors
[02:51] Kavir: got back in the ship
[02:51] Kavir: flew off zebes exploded I won
[02:51] Seppel: haha, what the hell
[02:51] Seppel: Really?
[02:51] Kavir: yes
[02:51] Haze: Zelda: A Link to the Past in 3 minutes
[02:51] Haze: they accomplish this with some bugs in the game
[02:51] Haze: so I think Kavir's metroid record is perfectly OK.
[03:18] Seppel: KAVIR WHEN YOU BEAT SUPER METROID DID YOU ACTUALLY DIE IN THE SPACE COLONY OR WHAT?
[03:18] Seppel: Trying to do it.
[03:18] Kavir: I ran out of time
[03:18] Seppel: Then you chose to try again?
[03:18] Kavir: I may have died to Ridley one or more times
[03:18] Kavir: Yes
[03:19] Seppel: You can't die to ridley unless you're really lucky.
[03:19] Kavir: and started back on the surface on the spaceship
[03:19] Kavir: went to both sides of the screen and then jumpd back in
[03:19] Seppel: OH
[03:19] Kavir: probably didn't then
[03:19] Seppel: You mean when you actually have to fight Ridley on Zebes?
[03:19] Seppel: Not in the intro to the game?
[03:19] Kavir: I DUNNO
[03:19] Kavir: IT WAS A SAVESTATE
[03:20] Kavir: BUT HE JUST FLEW AWAY
[03:20] Seppel: HAZE ANY INPUT DID YOU DO THIS SNESLYMPICS?
[03:20] Haze: yes
[03:20] Haze: I think Misteroo made us do it
[03:20] Kavir: I thought it was Neut
[03:20] Haze: he gave us a savestate of Ridley in the intro and we had to shoot him to make him drop the Metroid
[03:20] Kavir: didn't know Misteroo ever ran one
[03:20] Haze: It was Misteroo's
[03:20] Haze: I remember.
[03:20] Kavir: okay
[03:20] Haze: it's too abstract of a challenge for Neutrino to do
[03:21] Seppel: Haha.
[03:21] Seppel: So it was at the beginning of the game.
[03:21] Haze: so if we failed, we'd just load the save state again
[03:21] Haze: recording over and over until we finally did it
[03:21] Haze: not a very good challenge.
[03:22] Kavir: but we had very little time
[03:22] Kavir: and I misunderstood the instructions or gave up or something
[03:23] Kavir: SEPPEL AFTER LEAVING THE BIG TALL ROOM WITH RIDLEY THERE IS A SHORT CORRIDOR THAT ENDS IN A WALL YOU HAVE TO JUMPKICK OFF OF TO GET UP, RIGHT?
[03:23] Seppel: NO
[03:23] Kavir: WHAT IS IT
[03:24] Seppel: THAT IS THE SECOND TIME YOU HAVE TO FIGHT RIDLEY
[03:24] Seppel: FAR, FAR INTO THE GAME
[03:24] Kavir: THEN WHAT'S THE FIRST
[03:24] Haze: the first time is this small room
[03:24] Seppel: The fight where you have no energy tanks, only 99 health, no missiles, etc.
[03:24] Haze: where he's holding the Metroid capsule
[03:25] Haze: dark blue colours
[03:25] Kavir: I remember entering and leaving from the left
[03:25] Haze: the second time is where everything is red
[03:25] Kavir: I remember it being yellow or grey.
[03:25] Kavir: huh
[03:25] Seppel: haha
[03:25] Seppel: Hmm
[03:26] Seppel: Do you remember how much life you had?
[03:26] Kavir: no
[03:26] Kavir: I remember I didn't know how to use missiles if I had them
[03:26] Haze: if it was a glitch, it should've kept him at 99 energy, no tanks
[03:26] TheLastRoboKy: I have some speedkill avis of Emerald and Ruby Boss being killed
[03:26] TheLastRoboKy: Emerald's the green one underwater right?
[03:26] Kavir: I just jumped and shot a lot
[03:27] Seppel: HAZE OR KAVIR DO YOU HAPPEN TO (for some dumb reason) STILL HAVE THE SNESLYMPICS FILES?
[03:27] Kavir: and didn't take more than 99 damage if I had multiple tanks and didn't die
[03:27] Haze: okay I took a screenshot
[03:27] Haze: no I never kept them.
[03:27] Kavir: I did until I reformatted
[03:28] Kavir: ancient history
[03:28] Haze:
http://www.lylat.net/neoguri/ridley1.png
[03:28] Haze: that is the intro fight
[03:28] Haze: the one Misteroo wanted us to do
[03:28] Haze: so can you compare what happened to that?
[03:28] Kavir: that doesn't even look like the same GAME
[03:29] Kavir: but the blocks are in the right place
[03:29] Kavir: MEMORY HAZY
[03:29] Haze:
http://www.lotusreaver.com/articles/metroid/m3_ridley.gif this is the second Ridley battle
[03:29] Haze: I think this site dislikes hotlinking
[03:29] Haze: but I just pushed enter in the address bar and it appeared
[03:30] Seppel: it works
[03:30] Kavir: okay it was definitely not the second
[03:30] TheLastRoboKy: loads fine
[03:30] Kavir: definitely no lava pit
[03:30] Seppel: Okay
[03:30] Haze: okay, it just gave me some weird message when I got it from Google
[03:30] Seppel: We've established that it is indeed the first fight.
[03:30] Haze: for that one, you entered from the top right, and fell down to the lava pit
[03:30] Kavir: I remember entering from the left though
[03:30] Haze: okay
[03:30] Kavir: and leaving that way and running down the hall
[03:31] Seppel: Yes?
[03:31] Kavir: and getting to a 'dead end'
[03:31] Haze: unless it's a really weird glitch, then it's not the second Ridley
[03:31] Kavir: and jumping a lot and not getting up
[03:31] Haze: yeah, that's the intro space station
[03:31] Kavir: the timer ran out there
[03:32] Kavir: unless there was any hazard to kill myself on without going back from the dead end
[03:32] Haze: there isn't
[03:32] Seppel: None
[03:32] Haze: there's falling blocks that slow you down, but that's it
[03:32] Seppel: They don't damage you.
[03:32] Kavir: ran out of time then
[03:32] Haze: that's the only way to die there
[03:32] Haze: okay, so what happened next?
[03:32] Seppel: Then did you see the space colony blow up, if you remember?
[03:32] Kavir: I respawned back on samus's ship
[03:33] Seppel: ...really?
[03:33] Haze: if you saw a planet blow up instead of a mechanical thing, then it'd be weird.
[03:33] Haze: do you remember if it was a planet or space donut thing?
[03:33] Kavir: I don't remember any cutscene between running out of time and respawning
[03:33] Kavir: but it could have been the space station blowing up
[03:33] Seppel: Okay...
[03:33] Haze: playing this again....
[03:34] Kavir: samus's ship was on a planet, probably zebes since when I jumped back in after going to both sides of the screen and not opening any doors the zebes blowing up animation played and the credits rolled
[03:34] Seppel: haha
[03:34] Kavir: just dirt and rocks
[03:34] Kavir: there wasn't even anything in the area
[03:35] Haze: no rain?
[03:35] Kavir: maybe
[03:35] Haze: I assume the ground wasn't blowing up around you.
[03:35] Kavir: no enemies or hazards or items
[03:35] Kavir: It was... dirt
[03:35] Haze: THE SECOND BOMB SEQUENCE
[03:35] Haze: there's never any enemies around the ship
[03:35] Seppel: Maybe something to do with the bomb sequence triggering, and possibly glitching out.
[03:35] Kavir: I think there was a door on only one side, and I think it was the right
[03:35] Kavir: unless there were more up higher
[03:35] Haze: alright
[03:36] Kavir: since I couldn't get up higher
[03:36] Seppel: Then the game thinks there's a bomb sequence going, and accepts it as the end of the game.
[03:36] Seppel: I dunno.
[03:36] Kavir: I'm pretty sure there was no rain
[03:36] Kavir: it just seemed completely static
[03:36] Haze: normally, to finish the game, you have to go back to that area and jump into the ship, then it takes off and the credits roll
[03:37] Haze: but at that time, there's a timer ticking down
[03:37] Haze: so the key here is to figure how it gets from the space colony, and somehow time warps to Zebes.
[03:37] Seppel: So something either during or right at the end of the first bomb sequence triggers a glitch that makes you respawn at the ship, while still thinking there's a bomb sequence going off.
[03:37] Kavir: hmmm
[03:38] Haze: oh yeah, one question....
[03:38] Seppel: This is a job for people who stare at thousands of memory addresses.
[03:38] Haze: when you pushed to continue, did you see any map screens pop up?
[03:38] Kavir: I don't remember that part at all
[03:38] Haze: some weird hexagonal map
[03:38] Kavir: I remember it as skipping immediately to the ship
[03:38] Kavir: I don't even remember the continue screen
[03:38] Haze: really?
[03:39] Seppel: Did Samus pop out of the ship, just appear there, or make the DOOODEEEDOOODOOO DOOOOOOOO noise?
[03:39] Kavir: not sure it wasn't there, but it feels that way
[03:39] Kavir: NO SOUNDS WITH THIS MEMORY
[03:39] Seppel: Haha.
[03:39] Seppel: Okay.
[03:39] Seppel: I think we have enough to start a wild goose chase.
[03:39] Kavir: I think it did the platform coming out of the ship thing
[03:40] Kavir: may have been a landing sequence for the ship
[03:40] Kavir: ...not really, but at a guess, it was in mid-jump while the helmet was slamming into the median
[03:41] Kavir: like hitting the floor bit on the way down from a failed jump-kick
[03:41] Haze: did you shoot Ridley at all?
[03:41] Kavir: either that or standing underneath it facing the wall
[03:41] Kavir: I tried, don't know if I hit and can't remember if I figured how to shoot before the time ran out but I think it wasn't that short
[03:42] Haze: jump kick, you mean the spinning jump?
[03:42] Kavir: the one where I have no idea what I'm doing and am pretending I'm playing Megaman X
[03:42] Seppel: Okay
[03:43] Seppel: I managed to get the space colony to explode twice (haha), but no instant win yet.
[03:43] Haze: did the screen start rotating?
[03:43] Kavir: hmm, that means you broke the bomb sequence
[03:44] Kavir: I'm pretty sure the screen didn't rotate
[03:44] Kavir: might have been shaking
[03:44] Haze: okay, then it's not the last room
[03:44] Haze: was it a horizontal room?
[03:44] Kavir: it was the first room
[03:44] Haze: or that part where you're jumping up
[03:44] Kavir: I didn't travel vertically at all
[03:44] Kavir: after leaving Ridley's room
[03:44] Haze: the room with the computers and stuff?
[03:44] Kavir: it looked very nuclear powerplanty
[03:44] Kavir: don't know about computers
[03:45] Kavir: I just ran left
[03:45] Kavir: take a screenshot if you can
[03:46] Seppel: Okay. What I did was I made it to the top of the final screen as soon as timer hit zero, since you have about one second after it explodes to reach that spot.
[03:46] Seppel: Space colony explodes once.
[03:46] Seppel: You have the option to continue.
[03:46] Seppel: If you choose yes, space colony explodes again, this time with samus escaping
[03:46] Haze:
http://www.lylat.net/neoguri/ceres0.png
[03:47] Haze: the first hallway after leaving Ridley's room
[03:47] Kavir: that's the hallway allright
[03:47] Haze:
http://www.lylat.net/neoguri/ceres1.png the computer room
[03:47] Haze:
http://www.lylat.net/neoguri/ceres2.png further into the computer room
[03:47] Kavir: don't remember that, keep going to the end
[03:47] Haze:
http://www.lylat.net/neoguri/ceres3.png the room after that, you have to start going up
[03:48] Kavir: did those doors have to be shot open?
[03:48] Haze: nope
[03:48] Kavir: okay, I think that's exactly it then
[03:48] Kavir: couldn't get up there
[03:48] Haze: they open after a second if you stand in front of them
[03:48] Haze: so it's that last room you couldn't get up
[03:49] Kavir: Yes
[03:50] Seppel: Do you remember a room that tilted left and right?
[03:50] Haze: he said he didn't get to that one
[03:50] Seppel: Like actually tilted instead of being vertical.
[03:50] Kavir: I jumped at that over and over and ran up and down the stairs
[03:50] Seppel: Oh okay.
[03:50] Kavir: for about 45 seconds
[03:50] Haze: hah, I happened to have a savestate right at the second ridley fight
[03:51] Haze: how lucky yet useless
[03:51] Kavir: it was god
[03:53] Seppel: haha
[03:53] Kavir: I may have backtracked to the other rooms, don't think so though
[03:53] Seppel: THROWING THIS AT THE NESVIDEOS FORUM TO SEE IF THEY CAN COME UP WITH ANYTHING
[03:54] Kavir: GIVE ME THE ROM AND I'LL TRY
[03:56] Kavir: oops I don't have an emulator
[03:56] Seppel:
http://zsnes.com
[03:56] Kavir: THANKS
[03:56] Haze: we were using an older version of Zsnes, but not sure if that may have had an impact
[03:56] Seppel: I gotta go to bed, but good luck from here.
[03:57] Kavir: I WONDER IF THIS IS WHAT THOSE RAPE VICTIMS ON LAW & ORDER FEEL LIKE AFTER HAVING THEIR MEMORY PRODDED
[03:57] Kavir: goodnight
[03:57] Haze: then again we also had savestates and whatever
[03:57] Seppel: I'll try to see if Misteroo still has the rom and savestates and such.
[03:57] Seppel: Haze: Regardless, that shouldn't've happened.
[03:57] Haze: you posted on their forums?
[03:57] Seppel: Not yet.
[03:57] Seppel: SHOULD I?
[03:58] Haze: oh I thought you said you did
[03:58] Haze: CAN'T LET THEM STEAL THE GLORY??!??!
[03:58] Seppel: THROWING
[03:58] Haze: I doubt they'll have any clue.
[03:58] Seppel: Yeah.
[03:58] Haze: it's too obscure.
[03:58] Seppel: This is the kind of thing that requires everyone's effort.
[03:58] Seppel: JUST TO SEE IF THIS IS REALLY A GLITCH
[03:58] Haze: somehow the only way we can "prove" it exists is that Kavir has never played the game before
[03:59] Seppel: Haha.
[03:59] Haze: and he was able to describe some of the stuff later on
[04:08] Kavir: SO HOLDING THE JUMP BUTTON MAKES YOU GO HIGHER
[04:08] Seppel: haha
[04:08] Kavir: well I continued at the entrance instead of going to the ship
[04:09] Kavir: the savestate was already at the entrance to ridley's room
[04:17] Kavir: aha, you can't die at the beginning because the faster you hurt yourself the fast he flies off
[04:17] Haze: YES
[04:17] Haze: he retreats as soon as you go below 30 energy
[04:20] Seppel: Well, maybe if you purposefully aim youself at him, you might be able to.
So there you have it. I'll get back to you on any additional information.
