Earthworm Jim 2 (蚯蚓吉姆2) is an unlicensed port of the game of the same name, made for the Famicom by a team of (or at least related to) Ex-Sachen developers and published by Ka Sheng in 1996.

Mega Man: The Sequel Wars is a fan-made homebrew remake of Mega Man 4, 5 and 6 for the Sega Mega Drive, following in the footsteps of the officially released Mega Man: The Wily Wars. It aims to carefully recreate the NES classics while giving them a fresh 16-bit coat of paint and a rearranged soundtrack. More than that however, it also aims to bring a slew of new content, both through complete re-imaginings of the classics in EX Mode and a new gauntlet of levels in Wily Tower 2. And it all runs on the original Mega Drive hardware!

Released on Sega Mega Drive/Genesis, by Gamtec.

Released in 2000 on Game Boy Color, by Makon Soft.
