Among the files uncovered in a massive 2020 breach of internal server data from Nintendo are documents surrounding Project BB2, a never-released, iQue-branded version of the GameCube for the Chinese market. According to an executive summary from January 30, 2004, this system would've played games off of CD-ROM and DVD-ROM discs rather than the GameCube's proprietary format; consequently, it also would've been compatible with audio CDs and DVD video like the Panasonic Q. Project BB2 was also intended to feature karaoke support, owed to karaoke's high popularity in China.
