(Link to video)
This is my first submission !
This movie is a 956 frames (about 16 seconds) improvement over the current published run.

Game objectives

  • Emulator used: FCEUX 2.10.20
  • Aims for fastest time
  • Heavy death abuse
  • Abuses programming errors
  • Manipulates luck

About the game

Spelunker is a simple adventure game, but a difficult one. Much of the game's difficulty arises from the fact that the explorer cannot jump high or fall far, and therefore dies extremely easily. In Japan, this game's explorer is known as the most weakest hero in all action games. Among Internet users in Japan, the word "Spelunker" is used to mean " too weak" or "injure oneself frequently".

Sumarry

I gave up saving time before Level 4 because boat in Level 3 moves by 17 seconds frame rules, so you need 10 seconds or more improvements to take eariler boat.
All improvements comes from speed upgrades and lag reduction in Level 4.

Tricks

"jumping up the ropes" glitch
If you jump at the moment you catch the ropes(ladders) before descending, you can jump up the ropes(ladders).This is mere techniques, but surprisingly, this weak hero never dies unless you fall below the point you start to jump ! I used this trick to ride barrel in Level 3.
"jumping over the stones" glitch
you can jump over the stones by pressing left+right and jumping.You can use this tricks only in "left to right" direction because you always jump to right by this method.
Endless speed upgrade glitch
Generally, When you take drags in red vials, you get speed upgrades until remainig time of drug effect(RAM Address 0x00A5) become 0. However, if you take second drags when remaining time is 1, you can get Endless speed upgrade. Details of this glitch is here (Japanese) http://www.spelunker.jp/okure2.htm
Death management
When you die, you are respawned to the location of the last item you picked up or last vehicle you took, or starting point of level. So, you can manipulate your location after death by avoiding items. This is abused quite heavily in this movie.

Lag reduction

Large difference of Y positon after you die generates Lags.
This lags leads to delay of boats in Level 3 or elevators and poison gas in Level 4, so you need minimize these lags.

Stage by stage comments

  • Level 1
In the current published run, author get the endless speed upgrades in this level.
However, I didn't do that beacause that makes it impossible to maintain speed upgrades till level 4.
First blue key - I jumped up the ropes and died after I got the key in order to prevent lags after death.
Second blue key - manipulates Miracles(random item) to get 1UP for death abuse.
  • Level 2
In this level, I get endless speed upgrades. However, you can't go up the staris with speed upgrades.
Therefore, I got the blue key on the stairs before getting endless speed upgrades.
First blue key - I jumped and died by Flash (item like firworks) after getting the key.This is lag reduction, but still 26 frames lag occured.
Second blue key - manipulates Miracles(random item) to get 1UP for death abuse.
Third blue key - After getting the key and dying, 3 frames lag occured though I made effort to minimize lags by manipulating location after death.
  • Level 3
Second blue key - Normally, you can't ride barrel with speed upgrades because of jumping too far,but I could ride by using "jumping up the ropes" glitch!
you can't go up the stairs, so can't get the key directly. I got the coin and died to respawn to the coin and get the key.
  • Level 4
All improvements comes from this level as I noted, but this level is pretty simple, so no need to plan route or death management.

Special thanks and references

I hope you enjoy my run !

Yes vote. I found this a bit hard to follow, but likely because of the game; I could tell that a lot of effort went into the routeplanning, though. And you really show off how weak the hero is with the death abuse.

The game itself is pretty simple, see Randil's explanations because my English isn't good. As for this run, yeah...,it may be a bit hard to follow because of route planning and lag reduction, so I added stage by stage comments.

This game was released in 1985 (NES JPN version),so music is enough good,taking it to consideration :)

Wow, this feels noticeably faster than the previous run. Nice job, and welcome to TASVideos!
Used to be a frequent submissions commenter. My new computer has had some issues running emulators, so I've been here more sporadically. Still haven't gotten around to actually TASing yet... I was going to improve Kid Dracula for GB. It seems I was beaten to it, though, with a recent awesome run by Hetfield90 and StarvinStruthers. (http://tasvideos.org/2928M.html.) Thanks to goofydylan8 for running Gargoyle's Quest 2 because I mentioned the game! (http://tasvideos.org/2001M.html) Thanks to feos and MESHUGGAH for taking up runs of Duck Tales 2 because of my old signature! Thanks also to Samsara for finishing a Treasure Master run. From the submission comments:
Shoutouts and thanks to mklip2001 for arguably being the nicest and most supportive person on the forums.

Hadn't seen the original; I'm really glad you improved this and brought it to my attention! I love short little runs like this that still pack in a couple really surprising moments (setting the bomb so you could die on it later; standing right on the bomb and not dying) and good variety. Also, your technical improvements sound like they were quite solid too. Easy yes!

This video has an amusing (and well-made!) remix of the Spelunker music, which seems apropos.

The stream on the submission text doesn't seem to be HD, regardless of the 1080p included, and it surely doesn't have a logo or subs, so we need an encode. I'll take it.
All the best, Brandon Evans

Yeah, my youtube encode wasn't intended for TASvideo's encode. I have few knowleges about encode, especially HD or TASvideo's official one.

This is effect of item like star in SMB. It isn't time savers, but mere demonstration, so I'm glad this surprised you ;)

I have never played MSX version, but as far as I watched this, MSX version is almost the same as NES version, but very slow-paced...

The truly sad thing is this could easily have been the definitive version of spelunker. THe two button control scheme is perfect. But they made the controls really unfair to make up for what they toned down. The atari original played much better. But Japan is for th emost part only aware of the NES version. I think the original 8 bit one needs more love, especially in Japan. The best example of the difference between the two is that on the original versions you can jump off a ladder or rope every time by holding the button first, then tapping the stick. If you are jumpin gto another rope you should let go the stick, release the button, then pres it again if you need to jump again. With practice it becomes second nature, and you will be jumping nimbly from rope to rope to platform and back. Also, the falls that are less than a man height in the NES version are more like twice your height in the original. You can fall at leas 1.5 times your height and not die, and in fact have to.
