Realtec (和眾科技有限公司), also known as BIC (Brasil International Taiwan Corp, 八齊實業有限公司), is a Taiwanese company best known for publishing a number of unlicensed Sega Mega Drive/Genesis games mostly by AV Artisan.

They also released several of Codemasters' NES games in 60-pin Famicom format, along with a 60-pin version of the Game Genie. They are also believed to have been the original PCB manufacturer for Codemasters' NES games, based on their having "BIC" PCB codes. Other Famicom releases included Videomation by Western Technologies (a licensed game in the US) and Fire Dragon by Gamtec.

Realtec was also the parent company of Super Game, although these games were released under the name "Sugar Softec", presumably as a way to distance them from Realtec's more legitimate activities.
