List of Wario Land II pre-release and unused content
From the Super Mario Wiki
This is a list of pre-release and unused content for the game Wario Land II.
Wario Land II was originally scheduled to be released on November 10, 1997, seemingly under the title Wario Land 2. A screenshot released in that year depicts an underground area not seen in the final game. Broken ledges were found in the early version, and the chain of the grindstone carried by the D-Bat was longer than any chain in the released version. Breakable jars were also found in the underground area, which is not the case for similar places in the final version. The amount of Wario's coins is not seen in the screenshot.
In Japan, the Game Boy version of Wario Land II was planned to be released in February 1998. The game's Japanese website formerly used screenshots of the unreleased Japanese Game Boy version. Among them was a screenshot of the Japanese title screen, which resembles the Japanese Game Boy Color version except it did not have the border around the logo like the Western Game Boy version. Furthermore, the copyright date was still 1997, and the trademark symbol was a placeholder. An early gameplay screenshot with what looks like a different amount or placement of coins was replaced with a color comparison, but the title screen screenshot was not replaced until well after the release of the game.
