Time Diver: Eon Man is a cancelled beat ’em up developed by A.I for Taito for the NES. The game was finished, receiving a four-page strategy guide and review in issue 45 (February ’93) of Nintendo Power. Despite this, the game eventually disappeared from the Pak Watch section and was silently canceled.
According to game designer Shouichi Yoshikawa, the game was originally being developed as a sequel to Wrath of the Black Manta before being retooled.
Time Diver had 5 levels set at various points in time. These include the opening level Peaceful 1993, the Wild West, 1882, Devastated 2052, Devastated 1993, and a Peaceful Utopia version of 2052. An unusual feature (for the time) was that, with the exception of the first level, the stage order is randomized; allowing for some variation when playing through the game multiple times.

A playable ROM of Time Diver was somehow leaked online and you should be able to find it easily with google. You can read more info about the project in this article by Lost Levels’ Frank Cifaldi!
I still prefer the originals that Taito released for NES – “Power blade” and “Power blade 2”
I can’t find the rom anywhere. A google search only yields this page.
You should find it in the Lost Levels forum :) http://forums.lostlevels.org/viewtopic.php?t=1301
