This beats the previous publication by 25.1 seconds. An encode with the loading screens removed can be viewed here.

This movie abuses a couple of the game bugs in a surprising way.

Note that this is a Famicom Disk System game. Read What is FDS for more information.

Also note that this movie is about 42 seconds longer than the previous movie. This is due to the inaccurate (shorter) FDS load times emulated by famtasia.

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.

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".

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

This movie is 1.68 seconds faster than the previous version due to new routes in 1-1 and 1-2.

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.

In addition to the standard encode, there is an experimental encode produced in 10-bit YUV444 h.264, providing higher visual quality. You will need a very recent codec / media player (such as LAV Filters or mplayer2) to be able to play this experimental encode back. Feedback on this encode would be appreciated - please use the discussion thread for this movie for that purpose.

This is an 85 frame improvement over the previous movie by Deign.
