- Takes damage to save time
- Heavy glitch abuse
- Genre: Platform
Arumana no Kiseki is an FDS-only platformer with an interesting grappling hook mechanic. Perhaps not surprisingly for a rather complicated mechanic like this one, it can be abused heavily to clip through walls and most of several levels.

This run is an update of the predecessor movie that aiqiyou improved by 21.03 seconds through heavier optimization and better planning.

Castlevania II: Simon's Quest (Japanese title: Dracula II: Noroi no Fuuin (ドラキュラII 呪いの封印) is the story of Simon's horrible weekend without sleep. Two years after defeating Dracula, the hero is physically weakened by Dracula's curse. He must gather Dracula's remains and incinerate them at the ruins of Castlevania in order to end the curse.

Through a death warp only present in the FDS version, Fortranm and Burb defeat Dracula in record time. Please read the authors' comments for more details.

We also have a run of the NES version (which doesn't perform the death warp) right here.

- Takes damage to save time
- Genre: RPG
Esper Dream is an action RPG for the Famicom Disk System. It stars a boy with extrasensory perception (ESP) who has been transported into a book and must save the world inside by rescuing a mayor's daughter and collecting two special items. In addition to his ESP powers, he can use projectile weapons on his quest.

This run completes the game in record time by manipulating enemy position in battles, using the weapons and ESP powers strategically, and getting a large number of esper points (EP)--necessary for using the ESP powers--via an underflow glitch.

- Genre: Shooter
Otocky was created by Toshio Iwai in 1987 and was only released in Japan for the Famicom Disk System. It is best described as a musical side-scrolling shoot 'em up where the primary weapon is a ball which, when fired in one of eight directions, plays different musical notes on the primary instrument quantized to the beat of the background music.

Needless to say, when such a weapon is put into the hands of a tool-assisted speedrunner, you might just find yourself humming along to the end result.

This run was console verified using micro500's TASLink replay device (with 1 frame per latch poll).

- Heavy glitch abuse
- Genre: Platform
This game is Super Mario Bros., the original, but on the Famicom Disk System. It is much similar to the ROM version of the game, except for one minor difference that is demonstrated here.

The -1 stage is completely different. In the NES and Unisystem versions, the -1 stage repeats infinitely and cannot be completed, but in FDS, it can be completed, and then come -2 and -3.

The -3 stage in FDS is a castle level, and completing it ends the game, even though it says "princess is in another castle". The princess is not seen in the ending, but she is sighted twice in the -1 stage, as shown in this movie.

This movie is 84 frames faster than the previous one due to the use of a "cheap trick".

Watch this run being played back on a real console.

Mario has eaten too many poisonous mushrooms and as a result, decided to go on a furious killing spree. In this berserker state he has also gained the new secret ability to walk through walls at will.

Wondering how some tricks work? Information is available at Super Mario Bros. Tricks page.

This movie is 27 frames faster than the previous version due to new improvements in 1-2 and 8-4.

Watch this run being played back on a real console.


This is the real Super Mario Bros 2. It was never officially released in the USA and Europe. It was later ported to SNES, and released as "Lost Levels" on Super Mario All-stars.

FDS means Famicom Disk System. It was a Japanese disk-unit version of the NES.

- Takes damage to save time
- Genre: Action
The Mysterious Murasame Castle, also known as its original Japanese release title Nazo no Murasamejou, is a Famicom Disk System game developed by Nintendo EAD and published in 1986, only two months after The Legend of Zelda which it bears some similarities to. The story takes place in Edo period Japan. The titular Murasame Castle is taken over by a mysterious alien creature, who extends its power to four other neighboring castles. The daimyō lords of each castle are each given an evil sphere of power, and they use this power to summon armies of ninja and monsters to terrorize the nearby villages. Shōgun Tokugawa Ietsuna sends out samurai apprentice Takamaru to investigate the castles, defeat each castle lord along the way, and stop the aliens.

J.Y and BakuLuLU defeats said alien creature and restores peace to the region in record time, saving 5.31 seconds from the previous movie. in the process!


Viewers who have photosensitivity problems may want to avoid watching as there's a high amount of flashing visuals after defeating the final boss fight which can become uncomfortable to watch.

Please read the welcome page if you haven't already done so. It explains the rules and methods that apply to all of these movies, particularly the use of savestates and frame advance. Also refer to our Glossary to understand terms we use, such as TAS or other unfamiliar terms.
