In the run, the author makes usage of those special moves gained in-game to beat the opponents as fast as possible. He also takes advantage of an interesting quirk in the opponents' AI, ensuring that they do not get up after the first knockdown. For more details, see the run's comments.

In this run, the author drills through the ten time attack courses in slightly over seven and a half minutes. Furthermore, he aims primarily for in-game time, as it adds to the entertainment value and adds also to the strategy, as there are time bonuses in this mode which subtract time.

This movie plays the time attack mode; you won't believe the author's luck as he clears them so quickly you will wonder what is going on.

On the rare occasions we get to watch Sonic, we get to enjoy seeing him moving through walls, charging up for another dash, or making short work of bosses.

Besides the super fast speed itself, the speed also provides Sonic an ability (glitch) to pass through platforms and walls under certain conditions.

Mukki's TAS improves the previous run by 30.94 seconds, thanks to new routes and glitches explained in his comments.

Look no further! In this extremely high-speed run, Mukki demonstrates how to break the sound barrier and why Sonic is the fastest character in the video game universe.

Mukki's TAS improves the previous run by 43.18 seconds. Individual act improvements are listed in the submission text.

The author doesn't collect any of the Chaos Emeralds in this movie, but it demonstrates almost every single move that Sonic is capable of in this game.

It is recommended to read the author's novel to see why he chose to do many of the things he did.

In Kung-Fu Master, the player displays frightening reflexes that would be enough to obliterate any opponent.

In this run, the author, mugg, improves his previous run by changing the goal to getting the best in-game time, ignoring lag caused by enemy drops, among other things, in order to make for a more entertaining run. In addition, he changed the ROM used to the Japanese version, sacrificing some elements in order to make the fastest possible run. Please see the author's notes for more details.

Unlike later 8-bit Sonic games, there are significant differences in levels between the SMS version and the Game Gear version; here the latter is used primarily for faster boss fights.

If you like this run, also check out the run for SMS Sonic 2.

007 is ready for his incredibly popular first person shooter for the Nintendo 64. Rather than taking the usual stealthy strategy, secret agent 007 treats this first person shooter like any other and runs around shooting things with a complete disregard for human life, including his own.

While this run seems to be slower than the previous run, it actually plays all the regular levels faster and also plays two additional bonus levels!

Note: There are encodes of higher resolutions in the discussion thread.

Marina is quite a versatile cyborg. She can boost continuously in the air, ride vehicles, slide and jump like a maniac, and most importantly, shake. Make no mistake, you'll be seeing Comicalflop shake this thing, and even that thing quite a lot in this fast-paced run.

The game is broken down into 52 short areas, each of them having a separate timer. Because of this, the author aims to optimize the movie for shortest in-game time. Each stage is given a rank based on how fast the stage was completed; this run gets all S Ranks.

The game has some emulation errors, such as unnatural amounts of lag in some stages, and graphical glitches. See the author's comments for more details.

In this run, the author, RT-55J, tries to complete the game in the fastest in-game time. To do this, he uses many exploits that might have been removed if this game was actually released. For more details, as always, please see the author's notes.

Times for each track are:

• 0 = 36.19 (0.35 improved)
• 1 = 37.84 (0.40 -"-)
• 2 = 38.67 (0.19 -"-)
• 3 = 41.96 (0.02 -"-)
• 4 = 41.00 (0.02 -"-)
• 5 = 31.34 (0.40 -"-)

Main improvements come from taking ramps faster and a unique trick in which the author goes slower to get a better time. Look for further info in the author's comments.

Phil bested the predecessor movie by over a second thanks to better luck manipulation and decreasing the amount of jumps.

This movie aims for lowest in-game time. The completion times for each floor are: 1552, 1558, 1552, 1545, 1550.

There is more than just an appearance change to this game. Knuckles' abilities remain intact. If you haven't seen Sonic the Hedgehog completed before, you may wish to do so before seeing what a character with a spindash and gliding can accomplish.

There is also a run for a Tails hack of Sonic the Hedgehog, done by marzojr. It replaces Knuckles with Tails and gliding with flying.

Note: An IPS patch for the hack can be downloaded here: http://tasvideos-moviefiles.googlecode.com/files/ips%2Bpatcher.zip . It must be patched to REV 00.

Though, since the latter set of Emeralds isn't used for anything meaningful at all, the author has also provided a version that skips all the Super Emeralds and their respective bonus stages, which is about 9 minutes shorter. The movie files for this and other bonuses can be obtained from the author's comments.

For those that have seen the Knuckles 100% run (or just don't like waiting around), there is a second, smaller mkv that omits the emerald collection, loading/end of stage screens and removes the Hyper Sonic flash/music.

This run takes everything you know about Sonic & Knuckles and turns it upside-down. It extensively uses the "scroll objects offscreen to pass through them" trick to zip and warp to places that shouldn't be reached, break bosses, and effectively skip entire stages.

It is worth noting that nitsuja and Upthorn did not directly participate in the creation of this movie; instead, marzojr incorporated several additional tricks in several stages and spliced them in for a total improvement of 2:14.31 seconds over his last effort at doing the same.

This is the sixth run of this game, improving on the previous effort by 47.29 seconds with the use of new zips and improved precision.

To see a movie of this game that doesn't take advantage of zips, watch the "no zips" run by Aglar.

This long-awaited improvement to nitsuja's famous run saves 1:13.06 in real-time and 4418 in-game frames by general optimisation and several long-known additional glitches.

There is more than just an appearance change to this game. Tails' abilities remain intact. If you haven't seen Sonic the Hedgehog completed before, you may wish to do so before seeing what a character with flight and a spindash can accomplish.

There is also a run for a Knuckles hack of Sonic the Hedgehog, done by JXQ. It replaces Tails with Knuckles and flying with climbing and gliding.

This run is 2.73 seconds faster than the previous version. The improvements are mostly done in the Green Hill Zone, but also in the Spring Yard Zone.

Note: An IPS patch for the hack can be downloaded here: http://tasvideos-moviefiles.googlecode.com/files/ips%2Bpatcher.zip . It must be patched to REV 00.

Trivia: this game slightly predates the MegaDrive/Genesis version, so features the official first appearance of Sonic's flying mutant fox friend, Tails.

This run pauses for a few seconds between tracks to show the final track times.

Note that we do not normally accept runs starting from save states. See the Rules for more information.

This is the run where the author, Hoandjzj, clears everything about the game. If you're looking to watch a run that simply aims for the end, you can watch this run.

This movie sees the reinstatement of the in-game category, which was previously merged with the realtime run. Despite being slightly slower in terms of real time, this speedrun is both extremely optimised and breaks previous records once thought to be the limit of the game.
