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".

Sega Meganet, also known as the Net Work System, was an online service for the Mega Drive in Japan. Utilizing dial-up Internet access, Meganet was Sega's first online multiplayer gaming service, and functioned on a pay to play basis. The system functioned through the use of a peripheral called the Mega Modem and offered several unique titles that could be downloaded, and a few could be played competitively with friends. In addition, it shared technology and equipment with more serious services such as the Mega Anser, used for banking purposes. Though the system was announced for North America under the rebranded name "Tele-Genesis", it was never released for that region.
