Watch as nitsuja completely destroys this difficult game with amazingly precise movement. This playthrough saves Curly and finishes with the best ending after beating Ballos.

The program used to make this run, Hourglass, was also developed by nitsuja—with the creation of this run in mind. As such, it is our first published run of a Windows game.

This run features commentary by the author in the form of soft subtitles. There is also an experimental 10-bit YUV444 encode available, which requires relatively recent media player software / codecs (try LAVFilters for Windows, or mplayer2).

The game is markedly different than other Sonic games; aside from "improved" graphics and sounds, each level has 2 to 4 alternate versions that correspond to different time periods. Sonic can move between them to affect the gameplay and ending.

This run is approximately 37 seconds faster than upthorn and nitsuja's previous run thanks to various optimization and minor route changes. For more information on the improvements, the BIOS files used and a run for the Japanese version of the game, please read the author's submission notes.

There are two video encode files, the first recorded with the Japanese region music and the second with the American region music.

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

This movie is a 1.5 minute improvement to the previous author's movie, due to better maneuvers, luck manipulation and other tricks such as controlling two snakes at the same time. No warps are used.

There is also a more recent one-player run available.

The author controls both players when applicable rather than letting the CPU operate the helper.

For those interested, the obsoleted movie uses only one controller. This accounts for the large time difference between the two movies.

The damage for every move was mapped out carefully by monitoring the internal values of the RAM, to be able to choose the best attack for every situation. Luck was manipulated to make some enemies appear in more convenient positions.

Nitsuja's new version here is just over 1 minute faster than the last version due to playing extremely aggressively and taking as much damage as possible. Check the author's comments at the submission page for more information.

Ecco is capable of moving at very high speed but has little in the way of brakes. Turning corners without smashing into walls is tricky to say the least.

This run takes no damage, despite the fact that this was not intended to be possible.

We apologize for the less-than-average video quality in this AVI, but this game is really unfriendly to MPEG4 compression utilized by codecs such as XviD and H.264.

This movie is about 10 seconds faster than the previous publication due to some suprising fighting strategies.

By continuously switching between the two modes, it allows the player to go as fast as possible, which makes an otherwise boring game interesting.
