This is an unreleased prototype for the N64 which was recently dumped.

I decided that timing should end on the first frame on which the camera changes, because this is the point where it freezes if this game is played on console.

The first character is chosen (there are three) because she has a much higher maximum speed. The speed can be increased by sliding against walls and rock and whitewater currents and appears to have no cap (much like BLJing in Super Mario 64). Unfortunately, the speed does have to be reduced at some points to ensure that the kayaker does not go flying off the map and can actually "finish" the level.

I achieved a final time of 1:26.36 (it should be noted that this is game time and not real time).

This run takes advantage of the fact that the TAS input plugin does not have a limitation on the range of the analogue stick, meaning that I can extend it well beyond the intended maximum. This is what allows the kayak to move at hyperspeed. On console, due to the N64 controller's limitations, only a fraction of this speed can be achieved (to put this into perspective, the best time recorded on console is 3:36, using this character).

The YouTube video was created using screen capture software because Mupen's built-in capturer crashes every time you try to capture a video because it can't tell what framerate the game is supposed to run at (the ROM has no region identity despite the fact that it is clearly a USA ROM).

This run might be improvable but it probably isn't because although some of the movement in it looks questionable, the viewer must remember that there are a lot of turns in the level and if the speed isn't reduced then the kayaker will simply fly into oblivion.

Hack to fix Mupen64 builtin capture

  • Change byte at 0x00003E of the ROM from 0x00 to 0x45.
  • Change byte at 0x0000E8 of the M64 from 0x00 to 0x45.

This should make Mupen64 builtin AVI capture work on this movie (by setting the region correctly).

With thanks to aleckermit for testing a bunch of stuff for me on console, and Ilari for figuring out how to make the ROM play at fullspeed and the m64 be capturable in Mupen.


adelikat: Claimed for judging.
adelikat: Replaced submission file at the request of the author. This is a 966 frame improvement, from various improvements throughout the movie.
adelikat: Accepting the movie for publication. (Note about the vote count: While the yes % is lower than most pulblications, I counted no less than 3 votes that were based on misinformation that were later retracted).

Note to publishers: This movie should be tagged with both Unofficial Game, and Single Level


natt: Will be working with our new publisher in training on this one
