This site was founded in early December of 2003, shortly after Bisqwit discovered Morimoto's Super Mario Bros. 3 tool-assisted speedrun on the Internet.

Official Site History


Bisqwit found Super Mario Bros. 3 on the Internet. It was a low-quality Windows Media Video file (wmv). The video contained the text "super mario bross 3 time attack video" in the beginning and "Played by もりもと @やるきなす " in the end.
Intrigued, Bisqwit went to the websites mentioned in that video and discovered that Morimoto had created more videos for games such as Rockman, Rockman 2, and Gradius. Knowing some Japanese, Bisqwit studied how to play those movies, and the trails lead to the Famtasia Famicom emulator.
After finding that Famtasia could play those movies, Bisqwit discovered that those movies were not shown anywhere in the Internet, but that people would probably be interested in them. He was also bothered about the bad quality of the Windows Media Video file of Super Mario Bros. 3, so he started creating a toolset that would enable him to record those videos into AVI files and publish them.
As soon he got it working, he created the website, (an archived copy can be seen here: where he published those movies together with the AVIs, made downloadable with BitTorrent.
2003-12-06 onwards
Bisqwit spent a lot of time tracking sites that were linking to the newly created NESVideos site, and seeing what was being talked about there. He registered on boards and tried to correct misconception about the movies. He created and refined the sections on the site explaining those concepts, such as the "Myths and Facts" section.
In the meantime, he expanded the content from more of Morimoto's videos, and put an invitation for users' submissions. He also started creating a few movies on his own, such as Super Mario Bros. 2, Super Mario Bros and Castlevania.
Videos from the Doom Done Quick project were also processed and published.


Bisqwit noticed Arc had formed a site, and that it linked directly to some files provided by the NESvideos server. Bisqwit contacted him and thus began some cooperation between these two sites.
The first user submission was received from Arc. It was Ghosts 'n Goblins. It was encoded and published the same day.
The second user submission, not counting Arc's improvements to Ghosts 'n Goblins, was Contra by Mathieu Pronovost.
From here, the submission rate started increasing, soon attracting later prolific players such as Michael Fried and Jean-François Durocher (aka. Genisto).
The amount of documentation on the site had grown so much that the site had to get a dedicated URL instead of a single .html page. Bisqwit moved it to (an archived copy can be seen here:
The site was re-written using a wiki-engine.


Previously the NESVideos website had been under the domain of Bisqwit's personal website, To improve the profile of the site, Bisqwit purchased a dedicated domain name for the site, Despite the different address, it still ran on the same server.
Also, the name of the site changed. When before it was NESVideos, now it became TASVideos. The name change was mostly motivated by the increase of published movies on systems other than NES.


Bisqwit finds a higher calling and purpose, and decides to follow it. In an act of great humility, he states that he wants to see the community continue and thrive without his presence. He calls upon the long-time members to volunteer and take charge of the site over the coming year.


Bisqwit enacts a final deadline of September and states that the site must be moved by the end of the summer for to continue.
Nach and adelikat take over the server and IRC channel, and begin the transfer progress.
With the help of ShinyDoofy, adelikat and Nach have the new server up and running. has a new home, and a new future ahead of it.


BizHawk is unveiled by adelikat, as a purpose-built TAS emulator for a variety of platforms - the first emulator built from scratch to support TAS features, with development led by TASVideos staff and administration. This marks a shift away from only using open-source emulators forked to add TAS tools, allowing new TAS tool development (such as TAStudio) in a more unified way.
adelikat sets the groundworks for the tiered publication proposal, categorizing every publication in one of 3 tiers (Stars, Moons, Vault), and marking a fundamental shift in site goals from publishing only notable or entertaining TASes, to publishing any TAS speedrun record of any suitable game.
The switch to the tier system is implemented in the site over the course of the next few weeks, and dozens of submissions are unrejected and re-judged in consideration for Vault eligibility.


For the first time, TASVideos and TASing were represented at Games Done Quick with a 45-minute TAS showcase at AGDQ 2014, featuring dwangoAC, micro500 and Weatherton, and introducing TASBot for the first time. The showcase was so popular that the TASVideos site servers overloaded and briefly went offline during the block.
Many more appearances at GDQs and other speedrun/tech/charity conventions would follow.


TASVideos introduces an official Discord server, set up by Fog. At the time, it was only set up as an alternative option to the IRC channel, which was still the main hub for direct chat.


Following a general decline in activity, Fog hands over administration of the Discord server to Noxxa.


Due to controversies surrounding freenode, the IRC server which TASVideos' IRC channel resided on since 2005, the IRC channel was moved to Libera Chat. While the IRC channel had already long been overtaken in activity by the Discord server at this point, it effectively marked the end of using IRC as the "official" direct chat channel, with the Discord server becoming the primary official chat hub instead.
The tier structure is overhauled and replaced with a class system, with the Standard class for main category speedrun records and Alternative category for esoteric goals, replacing the Vault and Moon tiers respectively. Other than Stars, movies are no longer classed by entertainment value.
A change in site adminstration, as Nach is no longer Site Admin.


adelikat and site staff relaunch the website with a new open source architecture, maintaining the site's legacy by importing all existing wiki articles, forum posts, movies, submissions, and user files but with a redesign focused on modern web standards and accessibility.
adelikat announces his stepping down as admin in favor of feos and Memory taking up the Site Administrator role.
With Noxxa relinquishing several staff duties, Discord server ownership is transferred to fsvgm777.


TASVideos gains a third Site Administrator, as Samsara joins the administration team.

Emulator History

Famtasia (NES)

blip devises a patch to get Famtasia to display video at 60fps instead of its normal 20.
blip writes another patch, this one to display all 240 scanlines (instead of the 224 normally displayed by NTSC consoles).
2004-second half
As FCEU becomes accepted on the site and gradually swells in use, Famtasia starts to fall out of favor due to FCEU's superiority.
Bisqwit's Solomon's Key is published, which turns out to be the final Famtasia movie published on the site.
Famtasia is officially no longer allowed for submissions.

Snes9x (SNES)

The first SNES movie was submitted (and unofficially published) by Phil & Genisto. It was Contra 3: The Alien Wars.
A new rerecording version of Snes9x v1.43 was published and officially accepted on the site.

Runs made on Snes9x v1.43 are no longer accepted.
Runs made on any version of Snes9x are no longer accepted.

Bisqwit declares that Gens runs will be accepted on the site.
A run of Contra - The Hard Corps is accepted as the first Gens run on the site.

FCEU submissions are officially declared to be accepted on the site. Soon after, it was judged to be superior to Famtasia in every way, resulting in Famtasia's eventual obsoletion.
FCEU submissions in the form of .fcm movies are no longer accepted. However, they can still be accepted as converted FCEUX movies (.fm2).

With the release of the Mupen64Plus core of BizHawk years prior, Nach declares Mupen64-rr to be obsolete. This proves to be a divisive decision.
Movies made in the .m64 format, the movie format used by Mupen64-rr, are no longer accepted. However, movies made with Mupen64-rr for compatible games (i.e. Super Mario 64 and Mario Kart 64) and then converted into BizHawk's .bk2 format are still accepted.
