Sonic Jam
"Sonic Jam" is a compilation which contains the four main "Sonic the Hedgehog" games released on the Sega Genesis: "Sonic the Hedgehog", "Sonic the Hedgehog 2", "Sonic the Hedgehog 3", and "Sonic & Knuckles". Unlike future "Sonic" collections, "Sonic Jam" does not use a Genesis emulator; the games are proper ports, and all are nearly identical to the original Sega Genesis releases, with the exception of minor bug fixes. "Sonic Jam" emulates "Sonic & Knuckles" "lock-on technology"—a special feature that allows the player to merge elements of "Sonic & Knuckles" into previous games, resulting in changes to the level design as well as the choice to play as Knuckles the Echidna in "Sonic the Hedgehog 2" and Tails in "Sonic & Knuckles".

On May 22, 2006, North American company Super Fighter Team released "Beggar Prince", a game translated from a 1996 Chinese original. It was released worldwide and was the first commercial Genesis game release in North America since 1998. Super Fighter Team would later go on to release two more games for the system, "Legend of Wukong" and "Star Odyssey". In December 2010, WaterMelon, an American company, released "Pier Solar and the Great Architects", the first commercial role-playing video game specifically developed for the console since 1996, and the biggest 16-bit game ever produced at 64 Mb. "Pier Solar" is the only cartridge-based game which can optionally use the Sega CD to play an enhanced soundtrack and sound effects disc. In 2013, independent programmer Future Driver, inspired by the Disney film "Wreck-It Ralph", developed "Fix-It Felix Jr." for the Genesis.
