The Wario Land 2 Famiclone, often referred to simply as Wario Land 2, is an unofficial bootleg game. It is primarily a hack of Nintendo's Kirby's Adventure, made and released by J.Y. Company in late 1998 for the Famicom console. While named after Nintendo's Wario Land II for the Game Boy, this version adapts the gameplay and engine of Kirby's Adventure to the 8-bit NES architecture. Despite some glitches that occur in this particular bootleg, the only significant changes are graphical details. Almost all of the sprites of Kirby have now been changed to that of Wario. These cartridges often feature simplified graphics and sound.
