On Romhack Thursdays, we bring you interesting finds from the world of game modifications.
Some months ago there were the “Gigaleaks,” huge troves of internal Nintendo files and documents that revealed a lot about abandoned projects and the development history of popular games.
There was so much information in them that people are still discovering new details. One thing that was surprisingly overlooked was source code for the version of Super Mario Bros. included in the SNES remake within Super Mario All-Stars. The source contained quite a lot of interesting commented-out lines and other data, that seemed to indicate that it may have been a hacked-up version of the source to the original Super Mario Bros.
A lot (but not all!) of this has been covered on the Prerelease page for Super Mario Bros. on The Cutting Room Floor. You can go read about it there. There resides information on scrapped enemies and objects, weird modes and behaviors of existing objects, and lots of other curiosities.
For the 38th anniversary of the release of Super Mario Bros., Nimaginendo Games made a romhack that seeks to recreate many of these abandoned elements, and shows it off in a Youtube video. The hack can be downloaded from a link in the video’s description, but only for a little while! I should emphasize that it’s not a real prototype, but a speculative recreation based on information from the leaked source. It even has an older version of SMB’s title screen.
Extra! Did you know that an early working English title for Super Mario Bros. was Mario’s Adventure? And Nintendo of America even made a promotional flyer with that name! These images come from Flyer Fever:
