Prize Fighter: Heavyweight Edition was intended to be a Sega Saturn port of the Mega CD FMV boxing title Prize Fighter, which was originally released in North America in 1993.

As gamers who were around in the 1990s will recall, FMV (full motion video) titles were popular o the Mega CD, as the higher capacity memory of the  CD format allowed for video (albeit often grainy and low-resolution) in a way that cartridges did not.

The Saturn version of the game, titled Prize Fighter: Heavyweight Edition was in development by FMV specialists Digital Pictures from 1995 to 1996, but it never saw release due to Digital Pictures going bankrupt.

However, now, some 30 years later, a prototype version Prize Fighter: Heavyweight Edition for Sega Saturn has been uploaded to Archive.org, in both English and Japanese, along with a PDF of the North American version of the game’s manual.

The game and manual uploaded to Archive.org by Limited Run Games founder Josh Fairhurst, who now owns the back catalog of the game’s developer, Digital Pictures. In a post on X, Fairhurst stated that: “When I acquired the rights to the Digital Pictures game library, I found the unreleased SEGA Saturn version of Prize Fighter Heavyweight Edition. It’s now been preserved online and can be downloaded for free.”

Prize Fighter: Heavyweight Edition has also been made available for purchase on Steam for PC, and on the PS Store for PlayStation 4 and PlayStation 5.
