Boxing Legends of the Ring (known in Japan as ファイナルノックアウト (Final Knockout?)) is a boxing video game for the Mega Drive/Genesis and Super NES consoles. The boxers are represented by 2D sprites seen from over the shoulder of one of the fighters. The title of the game refers to the famous boxing magazine, The Ring, which the game is licensed to associate itself with. The following famous middleweight boxers are represented in the game: Sugar Ray Leonard, Roberto Durán, Thomas Hearns, James Toney, Marvin Hagler, Jake LaMotta, Sugar Ray Robinson, and Rocky Graziano. All of the fights in the game take place in the Las Vegas Hilton casino in the North American version. There are also advertising banners for HBO visible during fights that are not available in the Japanese version. In the Japanese version, the game takes place in a generic boxing ring using the publisher's name in place of the HBO advertisements found in the North American version. Even in the Japanese version, the options are mostly in English. A special version was released in Mexico called Chavez II; the game exchanged the English language words for Spanish and omitted some vocals.

Bugs Bunny in Double Trouble is a video game developed by Atod AB for the Sega Genesis and Game Gear, released in 1996. The game stars Bugs Bunny and features pre-rendered 3D graphics (similar to Donkey Kong Country for the Super Nintendo) Similarly to 1994's Mickey Mania: The Timeless Adventures of Mickey Mouse, the levels in this game are mainly based on individual Bugs Bunny cartoons from Warner Bros.' Looney Tunes and Merrie Melodies series, stringing them together by having Bugs trapped in a "Televisor" created by Yosemite Sam as a mad scientist. Seven of the levels are based on the Bugs Bunny cartoons Duck! Rabbit, Duck!, Bully for Bugs, Knighty Knight Bugs, Hare-Abian Nights, Spaced Out Bunny, Mad as a Mars Hare, and Hare-Way to the Stars, while the other level, entitled Haunted Hare, is based on elements of Bewitched Bunny and Hair-Raising Hare. Each level features objectives, designs, and opposing characters based on the source cartoon(s), though some levels take liberties to include plot elements, weapons, and obstacles that weren't present in the original cartoons. For example, the Hare-Abian Nights level features a duel with Yosemite Sam over a genie's lamp, and Spaced Out Bunny is essentially a race against Marvin the Martian to Mars. As well, the Duck! Rabbit, Duck! level does not have the snow present in the original cartoon, giving it a design closer to Chuck Jones' earlier "hunting trilogy" cartoons, like Rabbit Fire.
